David, thanks so far. I tried the same thing and set up a simple test-project to play with the ejb-jar.xml My result is as follows:
Everything works as expected if I override the settings within the same jar. If I try to override the settings from the referenced jar, it does not work. Do you have any idea about this? I had to adjust the ejb-jar.xml as follows, so that the entityManager is injected correctly. I use the ejb-jar.xml within my original project. The referenced jar only has an ejb-jar with an empty <ejb-jar />-tag ---------------------------------------------------------------- <?xml version="1.0" encoding="UTF-8"?> <ejb-jar xmlns="http://java.sun.com/xml/ns/javaee"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd"; version="3.0" metadata-complete="true" > <enterprise-beans> <session> <ejb-name>CustomerManager2Impl</ejb-name> <business-local>company.CustomerManager2</business-local> <ejb-class>company.CustomerManager2Impl</ejb-class> <session-type>Stateless</session-type> <persistence-context-ref> <persistence-context-ref-name>em2</persistence-context-ref-name> <persistence-unit-name>IisTestPU2</persistence-unit-name> <injection-target> <injection-target-class>company.CustomerManager2Impl</injection-target-class> <injection-target-name>em</injection-target-name> </injection-target> </persistence-context-ref> </session> <session> <ejb-name>CustomerManagerImpl</ejb-name> <business-local>company.CustomerManager</business-local> <ejb-class>company.CustomerManagerImpl</ejb-class> <session-type>Stateless</session-type> <persistence-context-ref> <persistence-context-ref-name>em</persistence-context-ref-name> <persistence-unit-name>IisTestPU</persistence-unit-name> <injection-target> <injection-target-class>company.CustomerManagerImpl</injection-target-class> <injection-target-name>em</injection-target-name> </injection-target> </persistence-context-ref> </session> </enterprise-beans> </ejb-jar> ---------------------------------------------------------------- So if I copy the CustomerManager2Impl into the same jar, everything works fine, but as soon as I copy this into another jar and reference this jar, the deployment does not work anymore. Here comes the output: ---------------------------------------------------------------- 2009-02-23 12:58:10,141 INFO OpenEJB.startup:70 - openejb.home = C:\01-development\06-workspace\simpleEjbTest 2009-02-23 12:58:10,141 INFO OpenEJB.startup:70 -

So there must be something else going on here. When we process annotations we actually update the descriptor that comes with the application and it is possible to set a flag so that it will be written back to disk allowing you to see the final and definitive set of metadata. Set the 'openejb.descriptors.output' flag to 'true' and scan the log output for the paths to the update ejb- jar.xml file(s). If what is going on doesn't become obvious, post the log output as well as the generated ejb-jar.xml. -David > > This is my business class from the referenced jar (where > CustomerManager is it´s local interface annotated with @Local): > ---------------------------------------------------------------------- > ------- > package company; > > @Stateless > public class CustomerManagerImpl implements CustomerManager { > > ... > @PersistenceContext > private EntityManager entityManager; ... > } > > ---------------------------------------------------------------------- > ------- > > Now I included an ejb-jar.xml in my /classes/META-INF directory within > my local project and redefined the EntityManager as follows: > > > ---------------------------------------------------------------------- > ------- <?xml version="1.0" encoding="UTF-8"?> <ejb-jar > xmlns="http://java.sun.com/xml/ns/javaee"; > xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; > xsi:schemaLocation="http://java.sun.com/xml/ns/javaee > http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd > " > version="3.0" > metadata-complete="true" > > <enterprise-beans> > <session> > <ejb-name>CustomerManagerImpl</ejb-name> > <business-local>company.CustomerManager</ > business-local> > <ejb-class>company.CustomerManagerImpl</ejb- > class> > <session-type>Stateless</session-type> > <persistence-context-ref> > <persistence-context-ref- > name>company.CustomerManagerImpl/entityManager</persistence-context- > ref-name> > <persistence-unit-name>IisTestPU</ > persistence-unit-name> > </persistence-context-ref> > </session> > </enterprise-beans> > </ejb-jar> > ---------------------------------------------------------------------- > ------- > > If I put anything wrong in this ejb-jar.xml I always receive an error. > So I assume, that the ejb-jar is interpreted correctly, but anyways I > receive an error when booting openEJB. > > ERROR - FAIL ...
