    Started with fresh cvs checkout of jbpm.3 and got this error

    David Sanchez Novice

      Happens when I do a "save and close." I even think I fixed this before but can't remmeber how. Many thanks if you can help!

          In most cases there is another error below this. Can you post the whole stacktrace?

            That was it actually.. Here is the whole page. Below that is some errors I got from a log I produced from starting up JBoss with jBPM for the first time.

            type Exception report

            message

              Tom and I struggled with this problem during the plane trip from Brussels to JBoss World in Barcelona a couple of hours before our demo... :-))
              The correct versions are on Tom's machine, but if I remember correctly you should make a change in the jboss-service.xml file in the conf folder of the jbpm configuration. Look for the mbean named "jboss:service=WebService" and comment the attribute named "DownloadResources". But beware, I could be completely wrong on this one. My memories have been poisoned by a lot of alcohol in the meantime ;-)
              Anyway, if you manage to fix this, you may have another problem with the webapp. But this last one was maybe due to the fact that we had no internet connection on the plane. It may have been an xsd download issue or something like this, but again not sure anymore.

              Hope this helps a little,
              Koen

                That helps a little. I actually tried that and the nasty message on startup went away. However my original problem of crashing on "Save and Close" didn't go away.

                I'll try to hunt down a solution for this since I may have fixed it in the previous version. It may have had to do with replaceing the "&" with "&" or perhaps changing the connection URL.

                Dave

                PS If you come up with somthing please let me know.

                  Can you post the stacktrace of the server at the moment of doing the "Save and Close"?

                    Thanks for helping out..

                    I'm only getting the file "boot.log" at jbossX/server/jbpm/log not the file "server.log" that would have that stack trace.

                    Is there property to change so that file is created?

                      Okay, figured out how to reconfigure Log4j to give debug level output.

                      Started jbpm using ./run.sh -c jbpm >> errorlog
                      I clipped the text below started from where the errors started to where they ended. I'm starting to look over it now to see if I can figure out what is going on.

                          Got the very latest jbpm.3 to work with my .par file but not with Websale. Not sure what is going on there but I'm able to move forward with my workflow.

                          Dave

                            Weekend does not count in opensource :-)

                            Is the error with the long stacktrace solved? The one that contains Caused by: java.lang.NullPointerException
                            at org.jbpm.db.save.UpdateTimersInterceptor.begin(UpdateTimersInterceptor.java:36)
                            at org.jbpm.tc.ContextBuilder.begin(ContextBuilder.java:132)

                            if not, this nullpointer is probably the cause of the error while submitting the form

                              We are working on this thing as I write. The webapp was apparently broken due to some architectural change in jbpm's configuration mechanism.
                              Please bear with us...

                              Cheers,
                              Koen
