Entities in .par files and session beans in .ejb3

faelin Nov 8, 2005 3:17 AM

Hi. I was thinking of puttin my persistence entities is a .par file, while the session beans that interact with them in another one - an .ejb3 archive. Yet, the session beans seem not to be able to find the persistant entities. I'm using pretty much the "default" server configuration. The exception I get goes "UnknownEntity: my.entity.here". and is a javax.ejb.EJBException.

I know that this would probably work if I put both files is an .ear archive, but what I want to be able to change them file by file in development time. Any ideas how could I do that?:D

Well, by me it was similar. According to the EJB3 trailblazer, only persistent entity beans should be in the .par file, and session beans in the .ejb3 file. The .par file contained /WEB-INF/persistence.xml, the .ejb3 file not. I had only one entity bean in .par and one stateless session bean in .ejb3. That stateless bean was DAO for the entity bean and when placed in the .ejb3, jboss was unable the inject persistent context to my DAO session bean.
Now I placed the session bean in the .par file and it's working,but it is in conflict with the recommandation, that only entity beans should be in .par archive.
So what is right approach. In the .par file should be all classes, which need acces to persistence context (typically including DAO stateless session beans)??? Or should I place DAO beans in the .ejb3 file together with WEB-INF/persistence.xml same as in .par file??? Currently it is not clear for me, the difference between the .par and .ejb3 files...
Thanks for any clarification.

The configuration settings for the persistence context should be specified in the META-INF/persistence.xml file in the .par archive not the WEB-INF as you've stated.

The rest should work as you've stated and as laid out in the walkthrough...

Sorry for confusing. The persistent.xml was in all my experiments placed in the META-INF directory...
