[jboss-user] [EJB 3.0] - Persisting POJO entities defined in a different jar
I have an existing jar file containing POJO entities (no JPA annotations, no
persistence.xml). I would like to persist there entities using a new EJB jar file which
contains a persistence.xml and a mapping file. Is this possible? I tried it, but I am
getting a InvalidMappingException:

Here are the relevant files in my ear. estore-common-1.0.jar contains the POJO entities.
estore-server-1.0.jar is the EJB jar that contains persistence.xml, mappings.xml and and a
stateless session bean called OrderServiceBean. I was hoping that the POJO entity classes
would be visible when parsing persistence.xml because they are in the classpath, but that
does not seem to be true.
| estore-1.0.ear
| |---estore-common-1.0.jar
| |---estore-server-1.0.jar
| | |---mappings.xml
| | |---META-INF
| | | |---ejb-jar.xml
| | | |---jboss.xml
| | | `---persistence.xml
| | `---samples
| | `---estorejpa
| | `---service
| | |---OrderService.class
| | `---OrderServiceBean.class
| `---META-INF
| application.xml
|
Here's my persistence.xml:
| <persistence>
| <persistence-unit name="EstorePersistenceUnit">
| <jta-data-source>java:/estore</jta-data-source>
| <mapping-file>mappings.xml</mapping-file>
| <properties>
| <property name="jboss.entity.manager.factory.jndi.name"
value="java:/persistence-units/EstorePersistenceUnit"/>
| </properties>
| </persistence-unit>
| </persistence>
|
Here's my mappings.xml:
| <entity-mappings>
| <description>eStore JPA Mappings</description>
| <package>samples.estorejpa.domain</package>
| <entity class="samples.estorejpa.domain.Customer"
name="Customer">
| <table name="CUSTOMER"/>
| <attributes>
| <id name="id">
| <generated-value/>
| </id>
| <basic name="version"/>
| <basic name="name"/>
| </attributes>
| </entity>
| ...
| </entity-mappings>
|
Any help would be much appreciated.
Thanks.
