    Help me ! How to get UserModule throuth the Injecting Servic

    wang wei Newbie

      Hi all,

      Today I want to do a example of get UserModule from the protal, so I do like the reference do :
      Injecting Services in the portlet context
      1.add the service in the jboss-portlet.xml

      <portlet-app>

      <service-name>UserModule</service-name>
      <service-class>org.jboss.portal.identity.UserModule</service-class>
      <service-ref>:service=Module,type=User</service-ref>

      </portlet-app>

      2.I use the HelloWorld example:
      so I change
      public class HelloWorldPortlet extends GenericPortlet
      {
      protected void doView(RenderRequest rRequest, RenderResponse rResponse) throws PortletException, IOException, UnavailableException
      {
      rResponse.setContentType("text/html");
      PrintWriter writer = rResponse.getWriter();
      writer.write("Hello World!");
      writer.close();
      }
      }
      to:
      public class HelloWorldPortlet extends JBossPortlet
      {
      protected void doView(JBossRenderRequest req, JBossRenderResponse resp) throws PortletException, IOException, UnavailableException
      {
      try {
      UserModule userModule = (UserModule) getPortletContext().getAttribute("UserModule");
      String userId = req.getParameters().getParameter("userid");
      User user = userModule.findUserById(userId);


      System.out.print(":::::::::::::::::::::::::::::::::::::::::::::::::::"+user.getUserName());
      }catch(Exception e){
      e.printStackTrace();
      }
      }
      }

      but when I start the server , it throw exception like:
      13:50:25,998 ERROR [PortletAppDeployment] Was not able to create service proxy
      java.lang.ClassNotFoundException: org.jboss.portal.identity.UserModule

          wang wei Newbie

          HI all,

          I add the jboss-portlet.xml file;

          <portlet-app>

          <service-name>UserModule</service-name>
          <service-class>org.jboss.portal.identity.UserModule</service-class>
          <service-ref>:service=Module,type=User</service-ref>

          </portlet-app>


          and use
          UserModule userModule = (UserModule) getPortletContext().getAttribute("UserModule");
          String userId = request.getParameters().getParameter("userid");
          User user = userModule.findUserById(userId);

          in the portlet, but it throw many exceptions.
          so I try to print out what's userModule.
          it's print [service=Module,type=User], how I can use UserModule in the portlet? can you example that to me? Thanks very much!
