Hibernate, as an ORM solution, effectively "sits between" the Java application and the Relational
Database, as can be seen in the diagram above. The Java application makes use of the Hibernate APIs
to load, store, query, etc its domain data. Here we will introduce the essential Hibernate APIs.
This will be a brief introduction; we will discuss these contracts in detail later.
<variablelist spacing="compact">

<section xml:id="architecture-current-session" revision="2">
<title>Contextual sessions</title>
<para>
Most applications using Hibernate need some form of "contextual" session, where a given
session is in effect throughout the scope of a given context. However, across applications
the definition of what constitutes a context is typically different; different contexts
define different scopes to the notion of current. Applications using Hibernate prior
to version 3.0 tended to utilize either home-grown <literal>ThreadLocal</literal>-based
contextual sessions, helper classes such as <literal>HibernateUtil</literal>, or utilized
third-party frameworks, such as Spring or Pico, which provided proxy/interception-based contextual sessions.
</para>
<para>
Starting with version 3.0.1, Hibernate added the <literal>SessionFactory.getCurrentSession()</literal>
method. Initially, this assumed usage of <literal>JTA</literal> transactions, where the
<literal>JTA</literal> transaction defined both the scope and context of a current session.
Given the maturity of the numerous stand-alone
<literal>JTA TransactionManager</literal> implementations, most, if not all,
applications should be using <literal>JTA</literal> transaction management, whether or not
they are deployed into a <literal>J2EE</literal> container. Based on that, the
<literal>JTA</literal>-based contextual sessions are all you need to use.
</para>
<para>
However, as of version 3.1, the processing behind
<literal>SessionFactory.getCurrentSession()</literal> is now pluggable. To that
end, a new extension interface, <literal>org.hibernate.context.spi.CurrentSessionContext</literal>,
and a new configuration parameter, <literal>hibernate.current_session_context_class</literal>,
have been added to allow pluggability of the scope and context of defining current sessions.
</para>
<para>
See the Javadocs for the <literal>org.hibernate.context.spi.CurrentSessionContext</literal>
interface for a detailed discussion of its contract. It defines a single method,
<literal>currentSession()</literal>, by which the implementation is responsible for
tracking the current contextual session. Out-of-the-box, Hibernate comes with three
implementations of this interface:
</para>
<itemizedlist>
<listitem>
<para>
<literal>org.hibernate.context.internal.JTASessionContext</literal>: current sessions
are tracked and scoped by a <literal>JTA</literal> transaction. The processing
here is exactly the same as in the older JTA-only approach. See the Javadocs
for details.
</para>
</listitem>
<listitem>
<para>
<literal>org.hibernate.context.internal.ThreadLocalSessionContext</literal>:current
sessions are tracked by thread of execution. See the Javadocs for details.
</para>
</listitem>
<listitem>
<para>
<literal>org.hibernate.context.internal.ManagedSessionContext</literal>: current
sessions are tracked by thread of execution. However, you are responsible to
bind and unbind a <literal>Session</literal> instance with static methods
on this class: it does not open, flush, or close a <literal>Session</literal>.
</para>
</listitem>
</itemizedlist>
<para>
Typically, the value of this parameter would just name the implementation class to
use. For the three out-of-the-box implementations, however, there are three corresponding
short names: "jta", "thread", and "managed".
</para>
<para>
The first two implementations provide a "one session - one database transaction" programming
model. This is also known and used as <emphasis>session-per-request</emphasis>. The beginning
and end of a Hibernate session is defined by the duration of a database transaction.
If you use programmatic transaction demarcation in plain JSE without JTA, you are advised to
use the Hibernate <literal>Transaction</literal> API to hide the underlying transaction system
from your code. If you use JTA, you can utilize the JTA interfaces to demarcate transactions. If you
execute in an EJB container that supports CMT, transaction boundaries are defined declaratively
and you do not need any transaction or session demarcation operations in your code.
Refer to <xref linkend="transactions"/> for more information and code examples.
</para>
<para>
The <literal>hibernate.current_session_context_class</literal> configuration parameter
defines which <literal>org.hibernate.context.spi.CurrentSessionContext</literal> implementation
should be used. For backwards compatibility, if this configuration parameter is not set
but a <literal>org.hibernate.engine.transaction.jta.platform.spi.JtaPlatform</literal> is configured,
Hibernate will use the <literal>org.hibernate.context.internal.JTASessionContext</literal>.

<title>Preface</title>
<para>
Developing Object-Oriented software that deals with data from Relational Databases can be cumbersome and
resource consuming. Development costs are significantly higher due to a paradigm mismatch between how data is
represented in objects versus relational databases. Hibernate is an Object/Relational Mapping (ORM) solution
for Java environments. ORM refers to the technique of mapping data between an object model representation to
a relational data model representation. See
<link xlink:href="http://en.wikipedia.org/wiki/Object-relational_mapping">Wikipedia</link>
for a good high-level discussion. Also, Martin Fowler's
<link xlink:href="http://martinfowler.com/bliki/OrmHate.html">OrmHate</link> article takes a look at many of
the mentioned mismatch problems.
</para>
<para>
Although having a strong background in SQL is not required to use Hibernate, having a basic understanding of the
concepts can help you understand Hibernate more quickly and fully. An understanding of data modeling principles
is especially important. Both <link xlink:href="http://www.agiledata.org/essays/dataModeling101.html"/> and
<link xlink:href="http://en.wikipedia.org/wiki/Data_modeling"/> are good starting points for understanding these
data modeling principles.
</para>
<para>
Understanding the basics of transactions and design patterns such as "Unit of Work"<citation>PoEAA</citation>
or "ApplicationTransaction" are important as well. These topics will be discussed in the documentation, but
a prior understanding will certainly help.
</para>
<para>
Hibernate not only takes care of the mapping from Java classes to database tables (and from Java data types to
SQL data types), but also provides data query and retrieval facilities. It can significantly reduce
development time otherwise spent with manual data handling in SQL and JDBC. Hibernate’s design goal is to
relieve the developer from 95% of common data persistence-related programming tasks by eliminating the need for
manual, hand-crafted data processing using SQL and JDBC. However, unlike many other persistence solutions,
Hibernate does not hide the power of SQL from you and guarantees that your investment in relational technology
and knowledge is as valid as always.
</para>
<para>
Hibernate may not be the best solution for data-centric applications that only use stored-procedures to
implement the business logic in the database, it is most useful with object-oriented domain models and business
logic in the Java-based middle-tier. However, Hibernate can certainly help you to remove or encapsulate
vendor-specific SQL code and will help with the common task of result set translation from a tabular
representation to a graph of objects.

<para>
This documentation is intended as a reference manual. As such, it is very detailed and great when you
know what to look for.

<para>
If you are just getting started with using Hibernate you may want to start with the
<citetitle pubwork="article">Hibernate Getting Started Guide</citetitle> available from the
<link xlink:href="http://hibernate.org/documentation">documentation page</link>. It contains quick-start
style tutorials as well as lots of introductory information. There is also a series of topical guides
providing deep dives into various topics.

"One of the first things that new users want to do with Hibernate is to model "

"One of the selling points of Hibernate (and really Object/Relational Mapping "
"as a whole) is the notion of database portability. This could mean an "
"internal IT user migrating from one database vendor to another, or it could "
"mean a framework or deployable application consuming Hibernate to "
"simultaneously target multiple database products by their users. Regardless "
"of the exact scenario, the basic idea is that you want Hibernate to help you "
"run against any number of databases without changes to your code, and "
"ideally without any changes to the mapping metadata."

"The first line of portability for Hibernate is the dialect, which is a "
"specialization of the <classname>org.hibernate.dialect.Dialect</classname> "
"contract. A dialect encapsulates all the differences in how Hibernate must "
"communicate with a particular database to accomplish some task like getting "
"a sequence value or structuring a SELECT query. Hibernate bundles a wide "
"range of dialects for many of the most popular databases. If you find that "
"your particular database is not among them, it is not terribly difficult to "
"write your own."

"Originally, Hibernate would always require that users specify which dialect "
"to use. In the case of users looking to simultaneously target multiple "
"databases with their build that was problematic. Generally this required "
"their users to configure the Hibernate dialect or defining their own method "
"of setting that value."
msgstr ""
#. Tag: para
#: portability.xml:69
#, no-c-format
msgid ""
"Starting with version 3.2, Hibernate introduced the notion of automatically "
"detecting the dialect to use based on the <interfacename>java.sql."
"DatabaseMetaData</interfacename> obtained from a <interfacename>java.sql."
"Connection</interfacename> to that database. This was much better, expect "
"that this resolution was limited to databases Hibernate know about ahead of "
"time and was in no way configurable or overrideable."
msgstr ""
#. Tag: para

#, no-c-format

"Starting with version 3.3, Hibernate has a fare more powerful way to "
"automatically determine which dialect to should be used by relying on a "
"series of delegates which implement the <interfacename>org.hibernate.dialect."
"resolver.DialectResolver</interfacename> which defines only a single method:"
"<programlisting role=\"JAVA\"><![CDATA[public Dialect resolveDialect"
"(DatabaseMetaData metaData) throws JDBCConnectionException]]></"
"programlisting>. The basic contract here is that if the resolver "
"'understands' the given database metadata then it returns the corresponding "
"Dialect; if not it returns null and the process continues to the next "
"resolver. The signature also identifies <exceptionname>org.hibernate."
"exception.JDBCConnectionException</exceptionname> as possibly being thrown. "
"A JDBCConnectionException here is interpreted to imply a \"non transient"
"\" (aka non-recoverable) connection problem and is used to indicate an "
"immediate stop to resolution attempts. All other exceptions result in a "
"warning and continuing on to the next resolver."
msgstr ""
#. Tag: para

"The cool part about these resolvers is that users can also register their "
"own custom resolvers which will be processed ahead of the built-in Hibernate "
"ones. This might be useful in a number of different situations: it allows "
"easy integration for auto-detection of dialects beyond those shipped with "
"HIbernate itself; it allows you to specify to use a custom dialect when a "
"particular database is recognized; etc. To register one or more resolvers, "
"simply specify them (seperated by commas, tabs or spaces) using the "
"'hibernate.dialect_resolvers' configuration setting (see the "

"When considering portability between databases, another important decision "
"is selecting the identifier generation stratagy you want to use. Originally "
"Hibernate provided the <emphasis>native</emphasis> generator for this "
"purpose, which was intended to select between a <emphasis>sequence</"
"emphasis>, <emphasis>identity</emphasis>, or <emphasis>table</emphasis> "
"strategy depending on the capability of the underlying database. However, an "
"insidious implication of this approach comes about when targtetting some "
"databases which support <emphasis>identity</emphasis> generation and some "
"which do not. <emphasis>identity</emphasis> generation relies on the SQL "
"definition of an IDENTITY (or auto-increment) column to manage the "
"identifier value; it is what is known as a post-insert generation strategy "
"becauase the insert must actually happen before we can know the identifier "
"value. Because Hibernate relies on this identifier value to uniquely "
"reference entities within a persistence context it must then issue the "
"insert immediately when the users requests the entitiy be associated with "
"the session (like via save() e.g.) regardless of current transactional "
"semantics. <note> <para> Hibernate was changed slightly once the implication "
"of this was better understood so that the insert is delayed in cases where "

<title>Preface</title>
<para>
Developing Object-Oriented software that deals with data from Relational Databases can be cumbersome and
resource consuming. Development costs are significantly higher due to a paradigm mismatch between how data is
represented in objects versus relational databases. Hibernate is an Object/Relational Mapping (ORM) solution
for Java environments. ORM refers to the technique of mapping data between an object model representation to
a relational data model representation. See
<link xlink:href="http://en.wikipedia.org/wiki/Object-relational_mapping">Wikipedia</link>
for a good high-level discussion. Also, Martin Fowler's
<link xlink:href="http://martinfowler.com/bliki/OrmHate.html">OrmHate</link> article takes a look at many of
the mentioned mismatch problems.
</para>
<para>
Although having a strong background in SQL is not required to use Hibernate, having a basic understanding of the
concepts can help you understand Hibernate more quickly and fully. An understanding of data modeling principles
is especially important. Both <link xlink:href="http://www.agiledata.org/essays/dataModeling101.html"/> and
<link xlink:href="http://en.wikipedia.org/wiki/Data_modeling"/> are good starting points for understanding these
data modeling principles.
</para>
<para>
Understanding the basics of transactions and design patterns such as "Unit of Work"<citation>PoEAA</citation>
or "ApplicationTransaction" are important as well. These topics will be discussed in the documentation, but
a prior understanding will certainly help.
</para>
<para>
Hibernate not only takes care of the mapping from Java classes to database tables (and from Java data types to
SQL data types), but also provides data query and retrieval facilities. It can significantly reduce
development time otherwise spent with manual data handling in SQL and JDBC. Hibernate’s design goal is to
relieve the developer from 95% of common data persistence-related programming tasks by eliminating the need for
manual, hand-crafted data processing using SQL and JDBC. However, unlike many other persistence solutions,
Hibernate does not hide the power of SQL from you and guarantees that your investment in relational technology
and knowledge is as valid as always.
</para>
<para>
Hibernate may not be the best solution for data-centric applications that only use stored-procedures to
implement the business logic in the database, it is most useful with object-oriented domain models and business
logic in the Java-based middle-tier. However, Hibernate can certainly help you to remove or encapsulate
vendor-specific SQL code and will help with the common task of result set translation from a tabular
representation to a graph of objects.
</para>
<para>
See <link xlink:href="http://hibernate.org/orm/contribute/"/> for information on getting involved.
</para>
<tip>
<para>
This documentation is intended as a reference manual. As such, it is very detailed and great when you
know what to look for.
</para>
<para>
If you are just getting started with using Hibernate you may want to start with the
<citetitle pubwork="article">Hibernate Getting Started Guide</citetitle> available from the
<link xlink:href="http://hibernate.org/documentation">documentation page</link>. It contains quick-start
style tutorials as well as lots of introductory information. There is also a series of topical guides
providing deep dives into various topics.

<appendix xml:id="appendix-legacy-bootstrap" xmlns="http://docbook.org/ns/docbook">
<title>Legacy Bootstrapping</title>
<para>
The legacy way to bootstrap a SessionFactory is via the <classname>org.hibernate.cfg.Configuration</classname>
object. Configuration represents, essentially, a single point for specifying all aspects of building
the SessionFactory: everything from settings, to mappings, to strategies, etc. I like to think of
Configuration as a big pot to which we add a bunch of stuff (mappings, settings, etc) and from which
we eventually get a SessionFactory.
</para>
<note>
<para>
There are some significant draw backs to this approach which led to its deprecation and the development
of the new approach, which is discussed in <xref linkend="bootstrap-native"/>. Configuration is
semi-deprecated but still available for use, in a limited form that eliminates these draw backs.
"Under the covers", Configuration uses the new bootstrapping code, so the things available there as also
available here in terms of auto-discovery.
</para>
</note>
<para>
You can obtain the Configuration by instantiating it directly. You then specify mapping metadata (XML
mapping documents, annotated classes) that describe your applications object model and its mapping to a
SQL database.
</para>
<example>
<title>Configuration usage</title>
<programlisting role="JAVA">Configuration cfg = new Configuration()
// addResource does a classpath resource lookup
.addResource("Item.hbm.xml")
.addResource("Bid.hbm.xml")
// calls addResource using "/org/hibernate/auction/User.hbm.xml"
.addClass(org.hibernate.auction.User.class)
// parses Address class for mapping annotations
.addAnnotatedClass( Address.class )
// reads package-level (package-info.class) annotations in the named package
.addPackage( "org.hibernate.auction" )
.setProperty("hibernate.dialect", "org.hibernate.dialect.H2Dialect")
.setProperty("hibernate.connection.datasource", "java:comp/env/jdbc/test")
.setProperty("hibernate.order_updates", "true");</programlisting>
</example>
<para>
There are other ways to specify Configuration information, including:
<itemizedlist>
<listitem>
Place a file named hibernate.properties in a root directory of the classpath
</listitem>
<listitem>
Pass an instance of java.util.Properties to Configuration#setProperties

Hibernate, as an ORM solution, effectively "sits between" the Java application and the Relational
Database, as can be seen in the diagram above. The Java application makes use of the Hibernate APIs
to load, store, query, etc its domain data. Here we will introduce the essential Hibernate APIs.
This will be a brief introduction; we will discuss these contracts in detail later.

<varlistentry>
<term>Transaction (<interfacename>org.hibernate.Transaction</interfacename>)</term>
<listitem>
<para>

</varlistentry>
</variablelist>
</para>
</section>
<section xml:id="architecture-current-session" revision="2">
<title>Contextual sessions</title>
<para>
Most applications using Hibernate need some form of "contextual" session, where a given
session is in effect throughout the scope of a given context. However, across applications
the definition of what constitutes a context is typically different; different contexts
define different scopes to the notion of current. Applications using Hibernate prior
to version 3.0 tended to utilize either home-grown <literal>ThreadLocal</literal>-based
contextual sessions, helper classes such as <literal>HibernateUtil</literal>, or utilized
third-party frameworks, such as Spring or Pico, which provided proxy/interception-based contextual sessions.
</para>
<para>
Starting with version 3.0.1, Hibernate added the <literal>SessionFactory.getCurrentSession()</literal>
method. Initially, this assumed usage of <literal>JTA</literal> transactions, where the
<literal>JTA</literal> transaction defined both the scope and context of a current session.
Given the maturity of the numerous stand-alone
<literal>JTA TransactionManager</literal> implementations, most, if not all,
applications should be using <literal>JTA</literal> transaction management, whether or not
they are deployed into a <literal>J2EE</literal> container. Based on that, the
<literal>JTA</literal>-based contextual sessions are all you need to use.
</para>
<para>
However, as of version 3.1, the processing behind
<literal>SessionFactory.getCurrentSession()</literal> is now pluggable. To that
end, a new extension interface, <literal>org.hibernate.context.spi.CurrentSessionContext</literal>,
and a new configuration parameter, <literal>hibernate.current_session_context_class</literal>,
have been added to allow pluggability of the scope and context of defining current sessions.
</para>
<para>
See the Javadocs for the <literal>org.hibernate.context.spi.CurrentSessionContext</literal>
interface for a detailed discussion of its contract. It defines a single method,
<literal>currentSession()</literal>, by which the implementation is responsible for
tracking the current contextual session. Out-of-the-box, Hibernate comes with three
implementations of this interface:
</para>
<itemizedlist>
<listitem>
<para>
<literal>org.hibernate.context.internal.JTASessionContext</literal>: current sessions
are tracked and scoped by a <literal>JTA</literal> transaction. The processing
here is exactly the same as in the older JTA-only approach. See the Javadocs
for details.
</para>
</listitem>
<listitem>
<para>
<literal>org.hibernate.context.internal.ThreadLocalSessionContext</literal>:current
sessions are tracked by thread of execution. See the Javadocs for details.
</para>
</listitem>
<listitem>
<para>
<literal>org.hibernate.context.internal.ManagedSessionContext</literal>: current
sessions are tracked by thread of execution. However, you are responsible to
bind and unbind a <literal>Session</literal> instance with static methods
on this class: it does not open, flush, or close a <literal>Session</literal>.
</para>
</listitem>
</itemizedlist>
<para>
Typically, the value of this parameter would just name the implementation class to
use. For the three out-of-the-box implementations, however, there are three corresponding
short names: "jta", "thread", and "managed".
</para>
<para>
The first two implementations provide a "one session - one database transaction" programming
model. This is also known and used as <emphasis>session-per-request</emphasis>. The beginning
and end of a Hibernate session is defined by the duration of a database transaction.
If you use programmatic transaction demarcation in plain JSE without JTA, you are advised to
use the Hibernate <literal>Transaction</literal> API to hide the underlying transaction system
from your code. If you use JTA, you can utilize the JTA interfaces to demarcate transactions. If you
execute in an EJB container that supports CMT, transaction boundaries are defined declaratively
and you do not need any transaction or session demarcation operations in your code.
Refer to <xref linkend="transactions"/> for more information and code examples.
</para>
<para>
The <literal>hibernate.current_session_context_class</literal> configuration parameter
defines which <literal>org.hibernate.context.spi.CurrentSessionContext</literal> implementation
should be used. For backwards compatibility, if this configuration parameter is not set
but a <literal>org.hibernate.engine.transaction.jta.platform.spi.JtaPlatform</literal> is configured,
Hibernate will use the <literal>org.hibernate.context.internal.JTASessionContext</literal>.

<title>JDBC batching</title>
<para>
JDBC offers support for batching together SQL statements that can be represented
as a single PreparedStatement. Implementation wise this generally means that drivers
will send the batched operation to the server in one call, which can save on network calls
to the database. Hibernate can leverage JDBC batching. The following settings control this
behavior.
</para>
<itemizedlist>
<listitem>
<para>
<literal>hibernate.jdbc.batch_size</literal> - Controls the maximum number of
statements Hibernate will batch together before asking the driver to execute
the batch. Zero or a negative number disables this feature.
</para>
</listitem>
<listitem>
<para>
<literal>hibernate.jdbc.batch_versioned_data</literal> - Some JDBC drivers
return incorrect row counts when a batch is executed. If your JDBC driver
falls into this category this setting should be set to <literal>false</literal>.
Otherwise it is safe to enable this which will allow Hibernate to still
batch the DML for versioned entities and still use the returned row counts for
optimitic lock checks. Currently defaults to false to be safe.
</para>
</listitem>
<listitem>
<para>
<literal>hibernate.jdbc.batch.builder</literal> - Names the implementation class
used to manage batching capabilities. It is almost never a good idea to switch from
Hibernate's default implementation. But if you wish to, this setting would name the
<interfacename>org.hibernate.engine.jdbc.batch.spi.BatchBuilder</interfacename>
implementation to use.
</para>
</listitem>
<listitem>
<para>
<literal>hibernate.order_update</literal> - Forces Hibernate to order SQL updates by the
entity type and the primary key value of the items being updated. This allows for more batching
to be used. It will also result in fewer transaction deadlocks in highly concurrent systems.
Comes with a performance hit, so benchmark before and after to see if this actually helps or
hurts your application.
</para>
</listitem>
<listitem>
<para>
<literal>hibernate.order_inserts</literal> - Forces Hibernate to order inserts to allow for
more batching to be used. Comes with a performance hit, so benchmark before and after to see

<title>Bootstrap</title>
<para>
The term <firstterm>bootstrapping</firstterm> refers to initializing and starting a software
component. In Hibernate we are specifically talking about the process of building a fully functional
SessionFactory instance or EntityManagerFactory instance for JPA. The process is very different for
each.
</para>
<note>
<para>
This chapter will not focus on all the possibilities of bootstrapping. Those will be covered
in each specific more-relevant chapters later on. Instead we focus here on the API calls needed
to perform the bootstrapping.
</para>

<!-- todo : point to "integrator guide" in regards to its effect on both forms of bootstrapping -->
<section xml:id="bootstrap-native">
<title>Native Bootstrapping</title>
<para>
This section discusses the process of bootstrapping a Hibernate SessionFactory. Specifically it discusses
the bootstrapping APIs as redesigned in 5.0. For a discussion of the legacy bootstrapping API, see
<xref linkend="appendix-legacy-bootstrap"/>
</para>
<section xml:id="bootstrap-native-registry">
<title>Building the ServiceRegistry</title>
<para>
The first step in native bootstrapping is the building of a ServiceRegistry holding the
services Hibernate will need at bootstrap and run time.
</para>
<!-- todo : point to the discussion about service registries, whether that remains as a topical guide or as a chapter in the "integrations guide" -->
<para>
Actually we are concerned with building 2 different ServiceRegistries. First is the
<interfacename>org.hibernate.boot.registry.BootstrapServiceRegistry</interfacename>. The
BootstrapServiceRegistry is intended to hold services that Hibernate needs at both bootstrap and
run time. This boils down to 3 services:
<itemizedlist>
<listitem>
<para>
<interfacename>org.hibernate.boot.registry.classloading.spi.ClassLoaderService</interfacename> -
which controls how Hibernate interacts with ClassLoaders
</para>
</listitem>
<listitem>
<para>
<interfacename>org.hibernate.integrator.spi.IntegratorService</interfacename> -
which controls the management ands discovery of
<interfacename>org.hibernate.integrator.spi.Integrator</interfacename> instances.
</para>
</listitem>
<listitem>
<para>
<interfacename>org.hibernate.boot.registry.selector.spi.StrategySelector</interfacename> -
which control how Hibernate resolves implementations of various strategy contracts. This
is a very powerful service, but a full discussion of it is beyond the scope of this guide.
</para>
</listitem>
</itemizedlist>
</para>
<para>
If you are ok with the default behavior of Hibernate in regards to these BootstrapServiceRegistry
services (which is quite often the case, especially in SE environments), then building the
BootstrapServiceRegistry can be skipped.
</para>
<para>
If you wish to alter how the BootstrapServiceRegistry is built, that is controlled through the
<interfacename>org.hibernate.boot.registry.BootstrapServiceRegistryBuilder</interfacename>:
</para>
<example>
<title>Controlling BootstrapServiceRegistry building</title>
<programlisting role="JAVA"><xi:include href="extras/native1.java" parse="text"/></programlisting>
</example>
<para>
The services of the BootstrapServiceRegistry cannot be extended (added to) nor overridden (replaced).
</para>
<para>
The second ServiceRegistry is the <interfacename>org.hibernate.boot.registry.StandardServiceRegistry</interfacename>.
You will almost always need to configure the StandardServiceRegistry, which is done through
<classname>org.hibernate.boot.registry.StandardServiceRegistryBuilder</classname>:
</para>
<example>
<title>Building a BootstrapServiceRegistryBuilder</title>
<programlisting role="JAVA"><xi:include href="extras/native2.java" parse="text"/></programlisting>
<programlisting role="JAVA"><xi:include href="extras/native3.java" parse="text"/></programlisting>
</example>
<para>
A StandardServiceRegistry is also highly configurable via the StandardServiceRegistryBuilder API.
See the StandardServiceRegistryBuilder javadocs for full details. Some specific methods of interest:
</para>
<example>
<title>Controlling StandardServiceRegistry building</title>
<programlisting role="JAVA"><xi:include href="extras/native4.java" parse="text"/></programlisting>
</example>
</section>
<section xml:id="bootstrap-native-metadata">
<title>Building the Metadata</title>
<para>
The second step in native bootstrapping is the building of a <interfacename>org.hibernate.boot.Metadata</interfacename>
object containing the parsed representations of an application's domain model and its mapping to
a database. The first thing we obviously need to build a parsed representation is the source
information to be parsed (annotated classes, `hbm.xml` files, `orm.xml` files). This is
the purpose of <classname>org.hibernate.boot.MetadataSources</classname>:
</para>
<example>
<title>Configuring a MetadataSources</title>
<programlisting role="JAVA"><xi:include href="extras/native5.java" parse="text"/></programlisting>
</example>
<para>
MetadataSources has many other methods as well; explore its API and javadocs for more information.
Also, all methods on MetadataSources allow for chaining should you prefer that style:
</para>
<example>
<title>Configuring a MetadataSources with method chaining</title>
<programlisting role="JAVA"><xi:include href="extras/native6.java" parse="text"/></programlisting>
</example>
<para>
Once we have the sources of mapping information defined, we need to build the Metadata object. If
you are ok with the default behavior in building the Metadata then you can simply call
MetadataSources#buildMetadata.
</para>
<note>
<para>
Notice that a ServiceRegistry can be passed at a number of points in this bootstrapping process.
The suggested approach is to build a StandardServiceRegistry yourself and pass that along to the
MetadataSources constructor. From there, MetadataBuilder, Metadata, SessionFactoryBuilder and
SessionFactory will all pick up that same StandardServiceRegistry.
</para>
</note>
<para>
However, if you wish to adjust the process of building Metadata from MetadataSources you will need
to use the MetadataBuilder as obtained via MetadataSources#getMetadataBuilder. MetadataBuilder
allows a lot of control over the Metadata building process. See its javadocs for full details.
</para>
<example>
<title>Building Metadata via MetadataBuilder</title>
<programlisting role="JAVA"><xi:include href="extras/native7.java" parse="text"/></programlisting>
</example>
</section>
<section xml:id="bootstrap-native-sessionfactory">
<title>Building the SessionFactory</title>
<para>
The final step in native bootstrapping is to build the SessionFactory itself. Much like
discussed above, if you are ok with the default behavior of building a SessionFactory from a Metadata
reference, you can simply call Metadata#buildSessionFactory.
</para>
<para>
However, if you would like to adjust that building process you will need to use
SessionFactoryBuilder as obtained via Metadata#getSessionFactoryBuilder. Again, see its
javadocs for full details.
</para>
<example>
<title>Building SessionFactory via SessionFactoryBuilder</title>
<programlisting role="JAVA"><xi:include href="extras/native8.java" parse="text"/></programlisting>
</example>
<para>
The bootstrapping API is quite flexible, but in most cases it makes the most sense to think of
it as a 3 step process:
<orderedlist>
<listitem>
Build the StandardServiceRegistry
</listitem>
<listitem>
Build the Metadata
</listitem>
<listitem>
Use those 2 things to build the SessionFactory

<section xml:id="bootstrap-jpa">
<title>JPA Bootstrapping</title>
<para>
Bootstrapping Hibernate as a JPA provider can be done in a JPA-spec compliant manner or using a proprietary
bootstrapping approach. The standardized approach has some limitations in certain environments, but aside
from those limitations, it is *highly* recommended that you use JPA-standardized bootstrapping.
</para>
<!-- todo : pointer to integration guide -->
<section xml:id="bootstrap-jpa-compliant">
<title>JPA-compliant bootstrapping</title>
<para>
In JPA we are ultimately interested in bootstrapping an javax.persistence.EntityManagerFactory instance.
The JPA specification defines 2 primary standardized bootstrap approaches depending on how the
application intends to access the javax.persistence.EntityManager instances from an
EntityManagerFactory. It uses the terms "EE" and "SE" for these 2 approaches, but those terms are very
misleading in this context. What the JPA spec calls EE bootstrapping is cases where a container
(EE, OSGi, etc) will manage and inject the persistence context on behalf of the application.
What it calls SE bootstrapping is everything else. We will use the terms
container-bootstrapping and application-bootstrapping in this guide.
</para>
<sidebar>
<para>
If you would like additional details on accessing and using EntityManager instances, sections 7.6
and 7.7 of the JPA 2.1 specification cover container-managed and application-managed EntityManagers,
respectively.
</para>
</sidebar>
<para>
For compliant container-bootstrapping, the container will build an EntityManagerFactory for each
persistent-unit defined in the deployment's META-INF/persistence.xml and make that available to the
application for injection via the javax.persistence.PersistenceUnit annotation or via JNDI lookup.
</para>
<example>
<title>Injecting a EntityManagerFactory</title>
<programlisting role="JAVA"><xi:include href="extras/jpa1.java" parse="text"/></programlisting>
</example>
<para>
For compliant application-bootstrapping, rather than the container building the
EntityManagerFactory for the application, the application builds the EntityManagerFactory itself
using the javax.persistence.Persistence bootstrap class. The application creates an entity manager
factory by calling the createEntityManagerFactory method:

<title>Application bootstrapped EntityManagerFactory</title>
