one persistence.xml multiple jars with entity beans

[pmadzik]

Hello,

Is any way to have multiple jars with entity beans and with single persistence.xml file in one EAR?

Only solution i found is "class" element in "persistence-unit", but necessity to explicitly list every entity bean is not satisfying.

Regards,

According to specs you can also lists jars. Lasst time I cheked this was not implemented (yet).

I tried "jar-file" element as well but it seems to be buggy because it seek for jar in $JBOSS_HOME/bin rather than in EAR

It is jira issue http://jira.jboss.com/jira/browse/EJBTHREE-560 but with resolution "Cannot Reproduce Bug".

It is http://jira.jboss.com/jira/browse/EJBTHREE-724. Unfortunately it is not fixed yet.

Is there a workaround ???

It's fixed in AS 4.2. Try it out on the latest version.

I'm afraid it has not been fixed in 4.2.

I've just download it. I still have the exception:

10:25:07,787 WARN [ServiceController] Problem starting service persistence.units:ear=itests-ear-1.0-SNAPSHOT.ear,unitName=audittrail

My persistence.xml is:

?xml version="1.0" encoding="UTF-8"?>
<persistence>
 <persistence-unit name="demo">
 ...
 </persistence-unit>
 <persistence-unit name="audittrail">
 <jta-data-source>java:/MyDS</jta-data-source>
 <properties>
 <property name="hibernate.hbm2ddl.auto" value="update"/>
 </properties>
 <jar-file>babar.j2ee-1.0-SNAPSHOT.jar</jar-file>
 </persistence-unit>
</persistence>

Is there a workaround for that ?

[wolfc]

Ah, the unit tests are wrong. They have ../ in front of the jar file. I've added this as a workaround in http://jira.jboss.com/jira/browse/EJBTHREE-724.

[jc7442]

OK, with the workaround it works.

Thanks
