Access SipFactory from EJB

Question

I'm using Mobicents SipServlets 2.1.547 with JBoss AS 7.2.0. I need to inject the SipFactory into an EJB and I'm using the @Resource annotation, which always results in a NullPointerException when I try to access the SipFactory. At this point I have @Resource SipFactory sf in my bean. Is there any reason why this wouldn't work? What would be the correct way to inject the SipFactory so I can access it from my bean?

UPDATE: I set the mapped name in the @Resource annotation, and now JBoss is giving me the following error on deployment:

JBAS014775:    New missing/unsatisfied dependencies:
  service jboss.naming.context.java.jboss.java:sip."com.mycompany.testproject.testapp".SipFactory (missing) dependents: [service jboss.naming.context.java.module.test."test-sip-1.0.0-SNAPSHOT".env."com.mycompany.testproject.testapp.ManagerBean".sf] 

ManagerBean.java:

@Resource(mappedName="java:sip/com.mycompany.testproject.testapp/SipFactory")
private SipFactory sf;

sip.xml:

Answer 1

Did you try with setting the mapped name ? Something similar to this piece of code below where you replace the appname part with your appname from sip.xml deployment descriptor.

@Resource(mappedName="java:sip/appname/SipFactory")
private SipFactory sipFactoryResource;
