Hi, I use JBoss 4.2.2 on Mac OS with JDK 1.5. First, I created a Session: @Stateful(name="ViewerBean") | public class ViewerBean implements Viewer, | ViewerLocal{ | Then I want to call the bean from a servlet: | public class ViewerServlet extends HttpServlet { | | //inject EJB | @EJB(mappedName="ViewerBean") | private ViewerBean bean; | | private static final long serialVersionUID = 1L; | | | /** | * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response) | */ | protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { | try { | List events = bean.getEvents(); | ... | I haven't added anything to the ejb-jar.xml as the annotations should be sufficient. But everytime I want to call bean.getEvents() I get a NullPointerException. I have an EJB3 project created in eclipse, as well as an EAR project. Both are deployed on the same server and the EAR client program references the EJB3 project, so I can use the ViewerBean in the client. Is this correct? Could you give me any hints on what I'm actually missing? Best regards, Andreas View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4216791#...
