Exception when completing a task in websale example

[khamburg]

I downloaded jbpm-jpdl-3.2.GA and installed the jbmp-console.war on Tomcat. I deployed the websale example process. I was able to log in to the console, initiate a new process instance, and move it through states until I got to "evaluate web order". When I clicked OK to advance to the fork node, I got an exception:

java.lang.NoSuchFieldError: FORCE
org.jbpm.graph.node.Join.execute(Join.java:105)

Can anyone shed any light on this? Should I submit a bug on JIRA for this?

[kukeltje]

please provide a full stacktrace and maybe even some debug logging. That would make it easier for us to help you.

[kukeltje]

if you look in the source the FORCE has something to do with hibernate. What version do you run on tomcat? maybe you need a newer version

[zipwow]

I discovered this problem myself when trying to run against a Hibernate version < 3.2
