The Open Services Gateway initiative (OSGi) specification describes a dynamic, modularized system. "Bundles"
|
||||||
|
(components) can be installed, activated, deactivated, and uninstalled during runtime, without requiring
|
||||||
|
a system restart. OSGi frameworks manage bundles' dependencies, packages, and classes. The framework
|
||||||
|
is also in charge of ClassLoading, managing visibility of packages between bundles. Further, service
|
||||||
|
registry and discovery is provided through a "whiteboard" pattern.
|
||||||

|

|
|

<para>
|
||||||

OSGi environments present numerous, unique challenges. Most notably, the dynamic nature of available
|
||||||
|
bundles during runtime can require significant architectural considerations. Also,
|
||||||
|
architectures must allow the OSGi-specific ClassLoading and service registration/discovery.

Hibernate targets the OSGi 4.3 spec or later. It was necessary to start with 4.3, over 4.2, due to our

dependency on OSGi's <literal>BundleWiring</literal> for entity/mapping scanning.

Rather than embed OSGi capabilities into hibernate-core, hibernate-entitymanager, and sub-modules,
|
||||||
|
hibernate-osgi was created. It's purposefully separated, isolating all OSGi dependencies. It provides an
|
||||||
|
OSGi-specific ClassLoader (aggregates the container's CL with core and entitymanager CLs), JPA persistence
|
||||||
|
provider, SF/EMF bootstrapping, entities/mappings scanner, and service management.

The Enterprise OSGi specification includes container-managed JPA. The container is responsible for

discovering persistence units and creating the <literal>EntityManagerFactory</literal> (one EMF per PU).
|

It uses the JPA provider (hibernate-osgi) that has registered itself with the OSGi

<literal>PersistenceProvider</literal> service.

No Enterprise OSGi JPA container currently supports JPA 2.1 (the spec is not yet released). For

testing, the managed-jpa example makes use of

Typical Enterprise OSGi JPA usage includes a DataSource installed in the container. The client

The easiest, and most supported, method of obtaining an <literal>EntityManager</literal> utilizes OSGi's

<literal>blueprint.xml</literal>. The container takes the name of your persistence unit, then injects

an <literal>EntityManager</literal> instance into your given bean attribute. See the

|
<literal>dpService</literal> bean in the managed-jpa QuickStart's

As of ORM 4.2, Envers is fully supported. Support for C3P0, Proxool, EhCache, and Infinispan were added in

4.3, however none of their 3rd party libraries currently work in OSGi (lots of ClassLoader problems, etc.).

We're tracking the issues in JIRA.

Multiple contracts exist to allow applications to integrate with and extend Hibernate capabilities. Most

apps utilize JDK services to provide their implementations. hibernate-osgi supports the same

extensions through OSGi services. Implement and register them in any of the three configurations.
|

hibernate-osgi will discover and integrate them during EMF/SF bootstrapping. Supported extension points

are as follows. The specified interface should be used during service registration.

Technically, multiple persistence units are supported by Enterprise OSGi JPA and unmanaged
|
||||||
|
Hibernate JPA use. However, we cannot currently support this in OSGi. In Hibernate 4, only one
|
||||||
|
instance of the OSGi-specific ClassLoader is used per Hibernate bundle, mainly due to heavy use of
|
||||||
|
static TCCL utilities. We hope to support one OSGi ClassLoader per persistence unit in
|
||||||
|
Hibernate 5.

Scanning is supported to find non-explicitly listed entities and mappings. However, they MUST be
|
||||||
|
in the same bundle as your persistence unit (fairly typical anyway). Our OSGi ClassLoader only
|
||||||
|
considers the "requesting bundle" (hence the requirement on using services to create EMF/SF),
|
||||||
|
rather than attempting to scan all available bundles. This is primarily for versioning
|
||||||
|
considerations, collision protections, etc.

Currently, Hibernate OSGi is primarily tested using Apache Karaf and Apache Aries JPA. Additional
|
||||||
|
testing is needed with Equinox, Gemini, and other container providers.

Hibernate ORM has many dependencies that do not currently provide OSGi manifests.
|
||||||
|
The QuickStart tutorials make heavy use of 3rd party bundles (SpringSource, ServiceMix) or the
|
||||||
|
<literal>wrap:...</literal> operator.

As previously mentioned, bundle activation is currently order specific. See the QuickStart

tutorials' <literal>features.xml</literal> for example sequences.

The environment should be considered STATIC. Hibernate currently does not support the ability
|
||||||
|
to dynamically add and remove client bundles during runtime. Doing so is typically
|
||||||
|
catastrophic. We hope to better support at least partially-dynamic environments in
|
||||||
|
Hibernate 5.

No Enterprise OSGi JPA container currently supports JPA 2.1 (the spec is not yet released). For
|

|
testing, the managed-jpa example makes use of

<link xl:href="https://github.com/brmeyer/aries/tree/jpa21">Brett's fork of Aries</link>. To work

with Hibernate 4.3, clone the fork and build Aries JPA.
