--------------------------------------------------------------
My Project structure is as follows
JBoss AS 7.1.3.Final-redhat-4
A war VWeb.war which contains an EJB , when VWeb is deployed I get the following

java:global/VWeb/QServiceImpl!com.vi.qciapi.QService
java:app/VWeb/QServiceImpl!com.vi.qciapi.QService
java:module/QServiceImpl!com.vi.qciapi.QService
java:global/VWeb/QServiceImpl
java:app/VWeb/QServiceImpl
java:module/QServiceImpl

I have got another war (ControlWeb-portlet.war) which is a liferay project and I am trying to access the above EJB within a bean from ControlWeb-portlet . The bean is @ViewScoped This has been done based on a link found http://www.verborgh.be/articles/2010/01/06/porting-the-viewscoped-jsf-annotation-to-cdi here
I have tried all these combinations but nothing seems to work

@Inject
QService qService;

@EJB
QService qService;

@EJB(mappedName="java:global/VWeb/QServiceImpl!com.vi.qciapi.QService")
QService qService;

@EJB(beanInterface=QService.class)
QService qService;

@EJB(mappedName="java:global/VWeb/QServiceImpl!com.vi.qciapi.QService")
QService qService;


I kept an EJB in the same project ControlWeb-portlet which is deployed as follows

    java:global/ControlWeb-portlet/CdiServiceImpl!com.clink.cdi.CdiServiceImpl
    java:app/ControlWeb-portlet/CdiServiceImpl!com.clink.cdi.CdiServiceImpl
    java:module/CdiServiceImpl!com.clink.cdi.CdiServiceImpl
    java:global/ControlWeb-portlet/CdiServiceImpl
    java:app/ControlWeb-portlet/CdiServiceImpl
    java:module/CdiServiceImpl

and I am able to inject the EJB with

@EJB
CdiServiceImpl cdiServiceImpl;

Is there anything specific that I have to while accessing an EJB from a different WAR

Thanks in advance
Charlie

I got it to work using the following approach:

1. Define EJBs as resources using the @Produces annotation:

public class Resources {
          @Produces
          @EJB(lookup = "java:global/.../WhateverService")
          private WhateverService whateverService;
}




# Inject the EJB resources in your bean using the @Inject annotation: {code}// ...

@Inject
private WhateverService whateverService;

// ...
{code}

Works like a charm. I'm also using a similar CDI view scope approach.
