EJB dependency injection

[pesho4uka]

Hello I have a "small" problem with the @EJB anotation.
I have created the following Bean:

@Stateless
public class CathegoryFacadeBean implements CathegoryFacadeRemote {
@PersistenceContext(type=PersistenceContextType.TRANSACTION) EntityManager em;

public List getAllCathegories() {
List cats = em.createNamedQuery("findAllCathegory").getResultList();

return null;
}

}

I am then using

@EJB CathegoryFacadeRemote cathegories;

from a JSF Backing bean. But the cathegories is null! I also tried to specify the "name" attribute of the anotation but no success. Can you tell me what to do in order to use the dependency injection?
Thank you in advance

You didn't say what version of JBoss you were using, but dependency injection for JSF managed beans is only available for JBoss 5 and JBoss 4.2.

http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossWithJSFCDDL

This is a feature that has to be enabled by the container, so just using JSF 1.2 alone isn't enough. If you are already using JBoss 5 or JBoss 4.2, post a reply here.

Regards,

Stan

Hello, sory for the delayed replay but i am still interested in how to do this
dependency injection. I am using jboss 4.0.5 and also Myfaces last version i think 1.1.4. Is this dependency injection specifict to JSF 1.2?

Yes, it is part of the JSF 1.2 spec. And actually, it is an optional feature. The only time it is required is for a JEE 5 compliant application server.

It won't work with JSF 1.1.

The feature will be available in JBoss 4.2 and JBoss 5.0.
