Hi,

I'm having some trouble while running my jBPM project on jboss 5. Just before the server starts, I get an error:

DEPLOYMENTS IN ERROR:
     Deployment "persistence.unit:unitName=myProj.ear/#BPM-DB" is in error due to the following reason(s): java.lang.ClassNotFoundException: org.jbpm.persistence.ProcessInstanceInfo from BaseClassLoader{jboss_project_path/jboss-service.xml}

I really can't understand why this happens, since I have the orm.xml, persistence.xml and ProcessInstanceInfo.hbm.xml. Can anyone help me with this? Google has not been my friend on this subject.

looks like you have a mix of JPA 1 and 2 and I don't think JBoss 5 supports JPA 2. You have persistence.xml configured with jpa2 but orm with JPA1, I would suggest to aligned both to be at JPA1 version level and try again.

Hey, thank you for replying.

I did as you sugested, but it's the same. The problem is those persistence classes aren't being found for some reason...even when I map the log ones, I get the same error. Got any idea what I'm missing here?

how do you deploy your application? is it war or ear? or maybe you use eclipse wtp to deploy from workspace?

basic question are you sure that all jbpm classes (especially drools-persistence-jpa.jar and jbpm-persistence-jpa.jar) are on the class path? What looks odd is this: jboss_project_path/jboss-service.xml have not seen this before...

I have solved my issue. As you said, the jpa jars were not all on the class path. Very basic problem, and I have no idea why the error mentioned jboss-service.xml...

So, *the solution*:

Download jbpm-persistence-jpa-x.x.x.Final.jar and drools-persistence-jpa-x.x.x.Final.jar and add them to your class path! In my case, I had to add them to my .ear manually, and later on will have to add the new stuff on Maven.

Thank you for the help, Maciej :)
