Remote access works fine, but local injection does not – any ideas?

randahl Mar 26, 2012 12:33 PM

I have created a business interface called SurveillanceFunctionality which is implemented by an EJB called SurveillanceBean. I am able to invoke the bean through the business interface from a remote, standalone application, but for some reason I cannot invoke the very same bean locally from a managed bean in my web war, which is deployed in the same EAR has the ejb.jar where the SurveillanceBean resides.

In my web app, I am trying to inject the EJB like this

@RequestScoped

@ManagedBean

public class AlarmEventView {

@EJB

SurveillanceFunctionality surveillanceFunctionality;

...

}

But when I do this, I get the exception shown at the bottom of this post, saying "Can not set com.wefend.services.surveillance.SurveillanceFunctionality field com.wefend.web.events.AlarmEventView.surveillanceFunctionality to com.wefend.services.surveillance.SurveillanceFunctionality$$$view19"

As I understand the specs, injecting an EJB which is part of the same App should work like a breeze, so I am a bit puzzled here. If anyone has any ideas to things I could try out, I would be grateful.

-----------------------------

My SurveillanceBean looks like this

@Stateful

public class SurveillanceBean implements SurveillanceFunctionality {

...

}

The business interface looks like this

public interface SurveillanceFunctionality {

public List<AlarmEvent> findRecentAlarms();

...

}

Note: I have tried declaring the SurveillanceFunctionality interface as @Local – that gives me the exact same exception.
