<div class="jive-rendered-content"><p>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.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>In my web app, I am trying to inject the EJB like this</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>@RequestScoped</p><p>@ManagedBean</p><p>public class AlarmEventView {  </p><p>          @EJB</p><p>          SurveillanceFunctionality surveillanceFunctionality;</p><p>...</p><p>}</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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"</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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.
