    Seam exception handling failing

    zzzz8 Newbie

      I've had a short history and issue in getting Seam exception handling working for me. It's important because I truly want to get this working since I would really want to handle exceptions the Seam way. I previously had issues that I thought might be due to Tiles eating the exceptions, so I switched to Facelets. Unfortunately, I'm seeing similar problems right now - i.e. the user is not redirected to the specified exception handling page.

      My current configuration is JBoss AS 4.0.5, Seam 1.1 CR1, and Facelets 1.1.11.

      Here is the stack trace I receive (the normal Tomcat stack trace) in the logs:

      2006-11-25 14:15:11,406 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/myapp].[Faces Servlet]] Servlet.service() for servlet Faces Servlet threw exception

      In terms of my code, I just simplified it (for testing) so that if the retrieveStatus method is called, it just throws an exception:

      @Stateful
      @Name("statusData")
      public class StatusBean implements StatusLocal {
      @DataModel("status")
      private List status = null;

      @Create
      @Factory("status")
      public final void retrieveStatus() throws ConnectionException {
      throw new ConnectionException();
      }

      @Remove
      @Destroy
      public final void destroy() {

      }
      }
