Calling EJB3 from a Faces BackingBean

Question

I have a simple web application, packed as an EAR, deployed on Glassfish. The EAR has a web module and an EJB module. The web module has a faces page, and a ManagedBean. The Faces page only has a button on it, and the button is tied to a method in the ManagedBean, and clicking the button does indeed fire the method.

The managed bean:

public class Bar {

    public Bar() {
    }

    @EJB StudentProfileFacade f;

    public void hello(ActionEvent evt) {
        System.out.println("*** f: " + f);
    }
}

The EJB is not getting injected, the error I get is:

Exception attempting to inject Unresolved Ejb-Ref com.web.Bar/f@jndi: com.StudentProfileFacade@[email protected]@Session@null into class com.web.Bar

What do I need to do so that the web module will find the EJB module, and the EJBs in it?

Hi,

try to do jndi lookup instead of di. It could look like:

private StudentProfileFacadeInt getStudentProfileFacade() { try { InitialContext ctx = new InitialContext(); return (StudentProfileFacadeInt) ctx.lookup("/StudentProfileFacade/local"); } catch (Exception e) { e.printStackTrace(); throw new RuntimeException("couldn't lookup StudentProfileFacade", e); } }

Where StudentProfileFacadeInt is a local interfejs for StudentProfileFacade.
