    EJB injection issue - Can not set field to org.javassist.tmp

    Rafael Ribeiro Novice

      I am trying to inject an EJB inside a Seam component using the @In annotation.
      I've already tried a few combinations:
      - having the components class= set as the Usual java interface (IWebUIFacade)
      - having the components class= set as the Remote EJB interface (IWebUIFacadeRemote)
      - having the components class= set as the bean itself
      - I also tried combinations of the attribute on the action (java interface, ejb interface, EJB Bean class...)

      But none of them is working. I am posting the stacktrace for the exception that is thrown
      with the configuration that seems to be the correct one.

      May be someone has any clue what I might be doing wrong.

      best regards,

      Code, configuration and stacktrace:

      foo.bar.server.facades.webui.IWebUIFacade

      package foo.bar.server.facades.webui;
      
      import foo.bar.server.model.user.User;
      
      public interface IWebUIFacade {
       public void saveUser(User user);
      }
      


      foo.bar.server.facades.webui.IWebUIFacadeRemote
      package foo.bar.server.facades.webui;
      
      import javax.ejb.Remote;
      
      @Remote
      public interface IWebUIFacadeRemote extends IWebUIFacade {
       String JNDI_NAME = "WebUIFacadeBean/remote";
      }
      


      foo.bar.server.facades.webui.impl.WebUIFacadeBean

      public class WebUIFacadeBean implements IWebUIFacadeRemote {
      
       @EJB
       private IUserManagerRemote userManager;
       public void saveUser(User user) {
       userManager.save(user);
       }
      
      }
      


      components.xml
       <component name="webUIFacade"
       scope="SESSION" jndi-name="WebUIFacadeBean/remote" auto-create="true"
       class="foo.bar.server.facades.webui.impl.WebUIFacadeBean">
       </component>
      


      foo.bar.web.business.user.UserAction
      [...]
      @Name("users")
      @Scope(ScopeType.EVENT)
      public class UsersAction extends StandardAction {
       @In
       IWebUIFacadeRemote webUIFacade;
      
       public IWebUIFacadeRemote getWebUIFacade() {
       return webUIFacade;
       }
      
       public void setWebUIFacade(IWebUIFacadeRemote webUIFacade) {
       this.webUIFacade = webUIFacade;
       }
      [...]
