There may be an issue with entity search in WebLogic 10.3.4.0 when using a separate <jar-file> for entities. On Glassfish 3, specifying only <jar-file> is sufficient, on WebLogic we need to also specify <class> - this should not be necessary for a managed @PersistenceContext. In my Java EE 5 projects I always run with explicit <class> elements - whether i am using a managed @PersistenceContext or an un-managed @PersistenceUnit. I have 2 nearly identical projects that use an external jar to contain the entity classes - that are referenced from a persistence.xml in the separate ejb-jar file. I turned off <class> elements and deferred to <jar-file> and/or manifest entry - as instructed by the Java EE 5 spec -and our own "Pro JPA 2 p.413". Note: I do not directly reference the EM from the WAR - so I don't need a ref there. On GlassFish V3 via NetBeans 6.9 I run fine with the following (no class elements as per spec = OK) <jar-file>CollatzModel-jar.jar</jar-file> <!--class>org.dataparallel.collatz.business.ActiveProcessor</class> <class>org.dataparallel.collatz.business.CollatzRecord</class> <class>org.dataparallel.collatz.business.Parameters</class> <class>org.dataparallel.collatz.business.UnitOfWork</class--> <!--exclude-unlisted-classes>false</exclude-unlisted-classes--> FINER: Class [org.dataparallel.collatz.business.CollatzRecord] registered to be processed by weaver. However on WebLogic 10.3.4, I have tried everything, relative paths ../lib, /lib, lib etc (there seems to be some difference on whether to state the path to the default EAR/lib dir) and I can only get WebLogic to find the entities if i also list them as class elements. The jar is being found evidently on the classpath - it is just that the entities are not processed unless also listed - which should not be necessary as they are annotated. Need to check an older JPA 1.0 server that does not use the patch jar. <jar-file>org.eclipse.persistence.example.distributed.CollatzModel.jar</jar-file> These should not be required <class>org.eclipse.persistence.example.distributed.collatz.model.ActiveProcessor</class> <class>org.eclipse.persistence.example.distributed.collatz.model.CollatzRecord</class> <class>org.eclipse.persistence.example.distributed.collatz.model.Parameters</class> <class>org.eclipse.persistence.example.distributed.collatz.model.UnitOfWork</class> <!--exclude-unlisted-classes>false</exclude-unlisted-classes--> >with <class> elements [EL Finer]: 2011-03-08 21:47:06.796--ServerSession(5694614)--Thread(Thread[[STANDBY] ExecuteThread: '3' for queue: 'weblogic.kernel.Default (self-tuning)',5,Pooled Threads])--Class [org.eclipse.persistence.example.distributed.collatz.model.CollatzRecord] registered to be processed by weaver. I will need to get the source for the WLS patch jar [com.oracle.jpa2support_1.0.0.0_2.0.jar]? It may be my MANIFEST - but likely not because when entity names are specified - they are found and processed in the jar lib. The issue may be in Both of the calls [getManagedClassNames() and getJarFileUrls()] to the server class PersistenceUnitInfoImpl return nothing. A later excludeUnlistedClasses() call is expected to be empty.
