    inifinite redirects

    Bill Levitt Newbie

      Hi,


      I've got a very basic Seam, Facelets, and EJB 3.0 application written based on the jee5/booking example. When I visit http://localhost/myContextRoot, I'm sent an infinite stream of HTTP 302 redirects to the debug.seam page. The debug page never appears, nor does anything else. I don't even know why the debug page is trying to display. What could I be doing wrong?


      Thanks in advance for any help.

          Probably you are executing an action on /home.xhtml view-id and that action redirects to view-id /home.xhtml. If this is true - change your implementation of this method to return nothing (e.g. public void execute()), if not - please post more info.

            Hi Goldmann,


            Thanks for the reply. No actions are executed because nothing renders to the screen for me to click/submit. The redirect to debug.seam is infinite.

              I don't know if I could help you more - I haven't run Seam on WebSphere...

                Bill Levitt Newbie

                Thanks, but this isn't related to Websphere because I have the Hotel Booking jee5 example application running just fine on the exact same Websphere server. It is something wrong with my configuration, I imagine.


                Anyone else have any ideas?

                  Bill,


                  Have you tried simplifying the application even further.


                  For instance, don't have home.xhtml extend template.xhtml to eliminate one piece of the puzzle.  And keep the content ultra simple like a Hello World :)


                  Also, eliminate the ejbs from the application and see what that does.


                  At this point if its still occurring, remove the context-param for Facelets.DEVELOPMENT.  When this is turned on and page rendering blows up, it will write a bunch of stuff to the screen.  This can be helpful at times, but based on my experience it can sometimes interfere with finding the root cause of a problem.


                  At this point, is there anything else you can remove from the mix?


                  Keith

                    Hi Keith,


                    Many thanks for the tips. I'll try your three suggestions. In the meantime, I made a few modifications to get the EAR to deploy on jboss 4.2.2 since jboss has better error logging :)


                    The ear deploys with no errors on jboss, but all requests to the application result in the same infinite redirect... just like on Websphere. However, I do get a stack trace this time. Yay!


                    So as to not clutter this post with too much noise, I've posted a trimmed version of the log with stacktrace here:


                    http://pastebin.mozilla.org/365789


                    The root cause of the problem appears to be javax.naming.NameNotFoundException expressionbuilder not bound
                    ...which points to a configuration error, no?


                    I'll try your suggestions and reply back.

                      seems like you jndi pattern is not correct, could you check that it was right?

                        Hi Srinivasan,


                        Yes, that the jndi pattern was wrong. However, when I fix the jndi pattern to what you suggest, the seam EJB in jboss-seam.jar cannot be found:


                        Name "comp/env/expressionbuilder/EjbSynchronizations" not found in context "java:".



                        jboss-seam.jar is in the root of my EAR, and application.xml defines it as an ejb jar:


                        <module>
                             <ejb>jboss-seam.jar</ejb> 
                        </module> 



                        Any ideas?

                          p.s. if i remove transaction:ejb-transaction
                          from components.xml, everything works just fine. But I don't want to remove this.

                            Seems like you missed a step in configuration:


                            http://docs.jboss.com/seam/2.0.1.GA/reference/en/html/websphere.html


                            resources/WEB-INF/web.xml


                              <ejb-local-ref>
                                <ejb-ref-name>websphere_example/EjbSynchronizations</ejb-ref-name>  
                                <ejb-ref-type>Session</ejb-ref-type>

                            this is need for servlet 2.4 containers..
