Re: Tomcat - Injection: No such property

I am having the same problem with Jetty. I am using the maven jetty:run plugin and when I put my SSBs in a separate EJB jar openEJB starts up fine. The EJBs are loaded correctly and I can get the local interface from JNDI, however when I call any method I get a NPE because nothing is injected. When I take the SSBs and place them in my WAR project everything works fine.

I am going to create an example app that demonstrates this problem. If someone could let me know where to upload it I would appreciate it.

Here is the output of the failed run:

I'm trying to run my application with Tomcat+openEJB, but I can't figure out why the EntityManager isn't injected correctly into the EAO sessionbean.
My war file is packed with the ejb.jar in \WEB-INF\lib.

The client is able to lookup the facade, but when the facade delegates the EntityManager actions to the EAO a null pointer exception is thrown.

Here's the log.

WARN  - Injection: No such property 'no.uib.gyro.domain.classification.TaxaEAOBean/em' in class no.uib.gyro.domain.classification.TaxaEAOBean

The @PersistenceContext annotation is inside the TaxaEAOBean, so it's not past to the EAO from the facade.

The strange thing is that when I put the EJB's in the war archive, it all works fine. Is there a difference to openEJB between adding ejb.jar in WEB-INF\lib or to put the beans directly in the WEB-INF\classes?

Thanks.
