    Invoking JBPM business process from Seam pageflow

    Aniket Nakhate Newbie

      Hi,

      I'm trying to invoke my business process from seam pageflow example. I have implemented NumberGuess pageflow example. I added myprocess.bpmn2 in component.xml file and myproject.jar file from JBPM into WEB\INF\lib of deployed war file.

       

      <bpm:jbpm>

            <bpm:process-definitions>

              <value>myprocess.bpmn2</value>

            </bpm:process-definitions>

            <bpm:pageflow-definitions>

               <value>pageflow.jpdl.xml</value>

            </bpm:pageflow-definitions>

         </bpm:jbpm>

       

      In pageflow.jpdl.xml, It is written as sub process.

       

      <process-state name="Invoke">

            <sub-process name="myprocess"/>

            <transition to="displayGuess"/>

         </process-state>

       

       

      Using: jboss-seam-2.3.1.Final,jbpm-6.1.0.Final,wildfly-8.1.0.Final as AS.

      I'm not sure whether I'm on the right track. Can someone please help me invoke the business process from Seam pageflow.?

          Please be warned that Seam 2.x doesn't work (actually nobody has tried that but it is almost true) with the latest JBPM 6.x or with 5.x or 4.x.

           

          Community Seam 2.3.x was using my updated fork of JBPM 3.2.10.SP3 to Hibernate 4 API (jboss-seam/pom.xml at Seam_2_3 · seam2/jboss-seam · GitHub) but that was just a quick hack to use higher Hibernate 4 API instead of Hibernate 3 API.

           

          If you would like to use JBPM 6 your path is Java EE 7 and CDI APIs.

            Just to let you know: you can give it a try: jBPM 3 -> Hibernate 4.3 Migration: petrandreev/jBPM3 at hib43 · GitHub

            (contains fixes for two forgotten JIRA issues, tests passed)

            Unfortunately I`ll stick to jBPM3 too until all my processes are migrated to BPMN.

              Hi Morek,

              I am using 2.3.1 and JBPM 3.2 on Jboss 5.1 and now I am migrating to WildFly 8.2, as per my analysis wildfly 8.2 supports JBPM6.2 so I am planning to migrate from JBPM 3.2 to 6.2. As per above comments I understood that seam 2.3.1 will not support JBPM 6.

               

              Is there any way to migrate my application to WidFly8.2.

               

              Thanks,

              Sreenath

                Hi, you can use Seam 2.3.x with JBPM 3.2 on Wildfly with bundled Hibernate libs in your application.

                 

                If you need to use higher version of JBpm like 4/5/6 you should refactor your application and replace Seam 2 with CDI.

                  Hi Marek,

                  Thank you for your response, Is there any hibernate bundle lib which is already developed ?.If there is no such bundle,could you please share the classes which need to change and what is the impact on the existing hibernate,

                    Hi Petr,

                    Do you mean those fixes are missing on top of this my fork mareknovotny/jbpm3-seam at development · GitHub ? That is possible.

                      Hi Sreenath,

                       

                      We are not on the same page , what I meant by bundling of hibernate jars is that you should include hibernate libs in your application deployment instead of relying on server runtime libraries. See an example in my older blog Seam 2 JPA example on JBoss AS7 in step 3 how to bundle hibernate jars in WAR type deployment. Similar way is when you need them in EAR deployment.

                       

                      Hope that helps!

                        Hi Marek,

                         

                        Thanks for your post, now we are on same page I guess. However I tried as you mentioned in the above link, but I am facing UserTransaction exception, please find the below error log.

                          you still are using hibernate at this error Validator 5.1.3 from server runtime as in your log is:

                          I should referenced DvdStore than the JPA example as there is also jbpm used anyway, read this Dvdstore example migration for JBoss AS 7.x too and what is important is addig exclusions for hibernate in jboss-deployment-structure.xml and set up transaction.manager_lookup_class property. Additionally set jboss.as.jpa.providerModule property in persistence.xml. As that DvdStore blog is for JBoss AS 7.0 there could be some small differences, but you should get the way how to solve it

                            Hi Marek,

                             

                            Do I need to specifically exclude the hibernate validator or excluding hibernate is sufficient, I have my Jboss deployment Structure file under ear/META-INF folder and I have excluded hibernate. Still it is loading the hibernate validator 5.1.3. Below is my deployment Structure file

                              I am getting the below exception.

                              java.lang.ClassNotFoundException: org.jboss.seam.pdf.DocumentStoreServlet.

                               

                              I identified this Jar exists in jboss-seam-pdf.jar and I added this Jar in project.war/WEB-INF/lib, still I am getting the ClassNoTFound Exception.

                               

                              Below is my stack trace

                                I guess you still have included above the dependencies to hibernate. Just remove these 2 lines and it should be done. And certainly you need hibernate-validator.jar in META-INF/lib of your ear.

                                  Are you sure you have updated war in your EAR deployment?

                                    Hi Marek,

                                     

                                    Thanks for the reply, I added the jboss-seam-pdf jar which is in Seam2.2.0 lib, but the class DocumentStoreServlet is not available in that Jar. I have added the appropriate jar and the issue was resolved. Bus still my jars are loading from hibernate 5.1. I and I am facing an issue while checking for Named queries, created a seperate thread for this

                                    Hibernate NamedQuery Exception while migrating from Jboss 5.1 to WildFly 8.2

                                    Please have a look at this issue and let me know if I am missing anything.
