    everything blocked after trying to edit from Guvnor

    Renzo Tomaselli Novice

      Hi, sequence was:

       

      - add "evaluation" process to Guvnor from inside Eclipse.

      - open Guvnor default package, list processes, select evaluation.

      - web editor shown, however no diagram appears.

      - close evaluation tab e open again.

      - designer blocked forever in "loading assets".

      - try to open the jBPM console: no way, everything blocked forever.

      - try running "ant stop.demo": no way, got stuck in "stop.jboss".

      - the last option: reboot.

          ... and to complete - after rebooting:

           

          - restarted ant start.demo.

          - run Guvnor application till clicking on defaultPackage: then got "400 Sorry, a technical error occurred. Please contact a system administrator."

          - logged out (seems nop).

          - tried again: now it seems to run fine.

          - the console runs as well.

            Try to tail -f the server.log in $jbpm_installer/$jboss/server/default/logs to see what errors you are actually getting so there is no guessing going on.

             

            *web editor shown, however no diagram appears  -> what oryx designer version are you using? There is an information button in the toolbar which should give you the version. Both of the evaluation processes open without issues with designer-1.0.0.053 and should also with designer-1.0.0.052

             

            *designer blocked forever in "loading assets". -> parsing error when opening the bpmn2 of your process, again server log should show you what happened

             

            *try running "ant stop.demo": no way, got stuck in "stop.jboss" -> whats stuck mean? Looking at server and boot logs will allow you not to have to guess

             

            *the last option: reboot - seriously?

             

            Please prodive more info. Thanks.

              I cannot see such a button ("about" says Version 5.2.0 final). Anyway from the lib dir I see designer-1.0.0.052-jboss.war (reinstalled jBpm yesterday).

              Server log, many errors:

               

              2011-07-19 15:03:46,151 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/drools-guvnor].[PackageDeploymentServlet]] (http-localhost%2F127.0.0.1-8080-5) Servlet.service() for servlet PackageDeploymentServlet threw exception

                  at org.drools.repository.RulesRepository.getAreaNode(RulesRepository.java:209)

               

              Many of:

              A couple of:

               

              ERROR 19-07 17:25:33,804 (UserInfo.java:<init>:51) Unable to init UserInfo

              at org.apache.jackrabbit.core.NodeImpl.resolveRelativePath(NodeImpl.java:249)

               

              and the final killer:

               

              2011-07-19 17:43:11,910 ERROR [org.apache.catalina.connector.CoyoteAdapter] (http-localhost%2F127.0.0.1-8080-2) An exception or error occurred in the container during the request processing

                  at java.util.LinkedHashMap.createEntry(LinkedHashMap.java:424)

               

              By "stuck" I meant never returning.

              I don't know jboss enough to be selective in killing its processes (Win7 64 bits), so rebooting was my last chance.

                Weird errors, does your user have permissions to edit directories in the $jbpminstaller directory or are they set to read-only?

                Guvnor uses apache Jackrabbit as the default JCR impl and it reads/writes your repository data in the installer by default to $installerdir/repository directory

                 

                How much memory are you running with? You may need more because of the OOM.

                  There are no permission problems, I installed all twice by unzipping jbpm-5.1.0.Final-installer-full.zip and running ant as described in install page. Home is c:/users/Sperkmandl/jbpm-installer

                   

                  I'm running win- 64 bits with 4 GB. And of course now (after yesterday reboot) everything seems running fine, except about the (XSRF attack?) log error, which appears often in today log (whatever it means).

                    The XSRF attack errors seems valid - see https://issues.jboss.org/browse/GUVNOR-1272. This is still an open issue. Please read comments in Jira for more info.
