The term bootstrapping 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.
@ -19,143 +22,6 @@ Instead, we focus here on the API calls needed to perform the bootstrapping.
During the bootstrap process, you might want to customize Hibernate behavior so make sure you check the <<appendices/Configurations.adoc#configurations,Configurations>> section as well.

[[bootstrap-jpa]]
=== JPA Bootstrapping
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, it is *highly* recommended that you use JPA-standardized bootstrapping.
[[bootstrap-jpa-compliant]]
==== JPA-compliant bootstrapping
In JPA, we are ultimately interested in bootstrapping a `javax.persistence.EntityManagerFactory` instance.
The JPA specification defines two 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 two approaches, but those terms are very misleading in this context.
What the JPA spec calls EE bootstrapping implies the existence of a container (EE, OSGi, etc), who'll 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.
For compliant container-bootstrapping, the container will build an `EntityManagerFactory` for each persistent-unit defined in the `META-INF/persistence.xml` configuration file
and make that available to the application for injection via the `javax.persistence.PersistenceUnit` annotation or via JNDI lookup.

[[bootstrap-jpa-xml-files]]
==== Externalizing XML mapping files
JPA offers two mapping options:
- annotations
- XML mappings
Although annotations are much more common, there are projects were XML mappings are preferred.
You can even mix annotations and XML mappings so that you can override annotation mappings with XML configurations that can be easily changed without recompiling the project source code.
This is possible because if there are two conflicting mappings, the XML mappings takes precedence over its annotation counterpart.
The JPA specifications requires the XML mappings to be located on the class path:
[quote, Section 8.2.1.6.2 of the JPA 2.1 Specification]
____
An object/relational mapping XML file named `orm.xml` may be specified in the `META-INF` directory in the root of the persistence unit or in the `META-INF` directory of any jar file referenced by the `persistence.xml`.
Alternatively, or in addition, one or more mapping files may be referenced by the mapping-file elements of the persistence-unit element. These mapping files may be present anywhere on the class path.
____
Therefore, the mapping files can reside in the application jar artifacts, or they can be stored in an external folder location with the cogitation that that location be included in the class path.
Hibernate is more lenient in this regard so you can use any external location even outside of the application configured class path.

[[bootstrap-jpa-metadata]]
==== Configuring the `SessionFactory` `Metadata` via the JPA bootstrap
As previously seen, the Hibernate native bootstrap mechanism allows you to customize a great variety of configurations which are passed via the `Metadata` object.
When you Hibernate as a JPA provider, the `EntityManagerFactory` is backed by a `SessionFactory`. For this reason, you might still want to use the `Metadata` object to pass various settings which cannot be supplied via the standard Hibernate <<appendices/Configurations.adoc, configuration settings>>.
For this reason, you can use the
https://docs.jboss.org/hibernate/orm/{majorMinorVersion}/javadocs/org/hibernate/boot/spi/MetadataBuilderContributor.html[`MetadataBuilderContributor`] class as you can see in the following examples.
[[bootstrap-jpa-compliant-MetadataBuilderContributor-example]]

====
[source, JAVA, indent=0]
----
include::{boot-spi-sourcedir}/metadatabuildercontributor/SqlFunctionMetadataBuilderContributor.java[tags=bootstrap-jpa-compliant-MetadataBuilderContributor-example]
----
====
The above `MetadataBuilderContributor` is used to register a `SqlFuction` which is not defined by the currently running Hibernate `Dialect`, but which we need to reference in our JPQL queries.
By having access to the
https://docs.jboss.org/hibernate/orm/{majorMinorVersion}/javadocs/org/hibernate/boot/MetadataBuilder.html[`MetadataBuilder`] class that's used by the underlying `SessionFactory`, the JPA bootstrap becomes just as flexible as the Hibernate native bootstrap mechanism.
You can then pass the custom `MetadataBuilderContributor` via the `hibernate.metadata_builder_contributor` configuration property as explained in the <<appendices/Configurations.adoc#configurations-bootstrap, configuration chapter>>
