Thomas,
did you try something like that ?
<ejb-jar>
<enterprise-beans>
<session>
<ejb-name>myJar.jar#mypackage.MyManager</ejb-name>
<ejb-class>mypackage.impl.MyManagerImpl</ejb-class>
<persistence-context-ref>
<persistence-context-ref-name>mypackage.impl.MyManagerImpl/em</persistence-context-ref-name>
<persistence-unit-name>PU</persistence-unit-name>
</persistence-context-ref>
</session>
</enterprise-beans>
</ejb-jar>
Regards,
Jean-Louis
