Subject [jira] [Commented] (ARIES-933) IllegalStateException when the peristence bundle gets resolved.

Emily Jiang commented on ARIES-933:
-----------------------------------

I posted in the forum for this jira, but it looks like you did not follow up that thread.


Hi Ioannis,
We have attempted this before. However, this will cause some other app server to fail as they
need EMF to perform entity enhancement using a mechanism other than using ByteCodeWeaving.
See jira https://issues.apache.org/jira/browse/ARIES-832 for more details.
Thanks
Emily

> Aries JPA tries to create the entity manager factories when the persistence bundle gets
in resolved state.
> With some persistence providers this can cause issues. For example Hibernate will try
to access the datasource via jndi when creating the EMF, causing the IllegalStateException
due to the fact that the persistnce bundle still has not context (is in resolved state).
> Even worse it will leave the EntityManagerFactoryManager is a wrong state, preventing
it to create the EMF when the bundle is created.
> There are two ways of approaching this issue:
> i) Don't try to create EMF when the persistence bundle gets resolved.
> ii) Catch possible errors and cleanup, so that EMF can be created when the bundle gets
started.
> I am going to attach a patch for the first appraoch, unless there is a good way for creating
EMF when the bundle gets resolved.
