    drools-guvnor: build package failures

    Renzo Tomaselli Novice

      Hi, I imported several process definition examples from Eclipse into Guvnor: Looping, HumanTask, BPMN2-ExclusiveSplit, BPMN2-gatewayTest, besides having already my own test example.

       

      First of all, this was a two step sequence since after a couple of imports, processes were listed but their opening showed an empty panel till I got a jboss outOfMemory error. Then the usual jboss stop/restart.

       

      Then I run build package for the defaultPackage and I got several errors for all processes.

      The common one is "unable to parse xml : Exception class java.lang.IllegalArgumentException : No interfaces found".

      Another one is "unable to parse xml : Exception class org.drools.RuntimeDroolsException : invalid package name".

       

      Indeed the package property was com.sample, so I turned it into defaultPackage. This raised other errors, such as "Parser returned a null Package", and "[ERR 102] Line 12:13 mismatched input 'true' in rule "RuleFlow-Split-com.sample.looping-4-5-DROOLS_DEFAULT"".

       

      Basically I'm totally lost with the designer.

          Hi Renzo, what version of Designer are you deploying? I just opened all the above mentioned processes with latest Designer version 1.0.0.054 which you can get from sourceforge: http://sourceforge.net/projects/jbpm/files/designer/ and all of them open up fine in guvnor and also fully round-trip.

          Most likely you are using an older Designer version. If you are using jbpm-installer you can change the version of designer in build.properties:

           

          designer.version=1.0.0.054-jboss

          designer.url=http://sourceforge.net/projects/jbpm/files/designer/designer-1.0.0.054/

           

          then delete the designer war in $jbpm-installer-dir/lib directory and run

          ant clean.demo

          ant install.demo

          ant start.demo

           

          Hope this helps.

            In order to build the package your processes are in (in Guvnor) you have to set the correct package attribute to your process, otherwise the package will not build. Since your Guvnor package you are uploading the processes into is most likely not the same name as what the processes you are uploading have defined (since they are from jbpm examples module) you would need to open the process in Designer, locate the packages attribute for the process and change it to the name of the guvnor package it is in now.

              I'm using designer 1.0.0.0.54  (25.579.520 bytes).

              Imported processes open ok, it's just that building the package that raises errors.

              Also I guess that installing an update requires changing designer.version/url in build.properties.

               

              Btw, the "no interfaces found" error occurs also for a simple test process created by the designer itself.

               

              About the package name: should it be "defaultPackage" (to have console visibility) or anything else ? I tried that name (since it's where I imported processes) but I got even more errors as reported in my initial post.

                Can you paste the bpmn2 of your simple process you created with Designer that creates the "no interfaces found" error (while working on the process you can view it's source in the Guvnor tab go to Source->View Source)?

                 

                jbpm-console currently looks at defaultPackage only. You would have to put all your processes in Guvnor's defaultPackage and make sure your processes specify the same in the package attribute. Ability for jbpm-console to look up processes in all packages has just been added in master via https://issues.jboss.org/browse/JBPM-3320.

                      Regarding the build errors. Processes tha cause the build problems you are seeing are examples that use XPath dialect, but we have not added out-of-the-box support for XPath expressions yet.

                      Any way you could upload the raw bpmn2 of your simple process or pastebin/gist it somewhere?

                        Renzo Tomaselli Novice

                        Not sure I understand what "raw bpmn2" is, I thought that the xml source I posted is complete and self-containing.

                        Btw, I did not use XPath expressions.

                        Also all imported examples raise the "no interfaces found" error.

                          Tihomir Surdilovic Master

                          Was hoping I would not have to get rid of the line numbers in the bpmn2 you pasted, but did anyways now. I see the issue, it is the Designer currently does not give you a way to declare an interface for service tasks. I will raise a jira and fix it for the next Designer version.

                          • 10. Re: drools-guvnor: build package failures
                            Tihomir Surdilovic Master

                            As a workaround until this is fixed in Designer, if you use service tasks you can create your process in Eclipse and upload it to guvnor. Just do not open it in designer and save it because it will change the bpmn2, getting rid of the interface definition(s).

                            Hope this helps.

                              Ok, many thanks, that was the first point.

                              Next one is about why errors become worse when I rename the package name of Looping to defaultPackage.

                              • 12. Re: drools-guvnor: build package failures
                                Tihomir Surdilovic Master

                                https://issues.jboss.org/browse/JBPM-3321 - watch it if you want.

                                 

                                Regarding the other errors, I was getting things like:

                                Unable to Analyse Expression $startMessage[@subject = 'foobar']: [Error: reference to undefined interceptor: subject] [Near : {... $startMessage[@subject = 'foobar'] ....}] ^ [Line: 1, Column: 16]

                                These types of build errors go back to what I was saying about no out-of-the-box support in jbpm for XPath expressions (those examples seem to use the XPath dialect).

                                • 13. Re: drools-guvnor: build package failures
                                  Renzo Tomaselli Novice

                                  How to proceed then ?

                                  The package does not build with these errors.

                                  As a consequence (I guess) the console process list shows just Evaluation and nothing else, while this process does not appear in Guvnor defaultPackage.
