[jboss-user] [JBoss jBPM] - Re: LinkageError
I'm wandering if I'm ending a task instance correctly since I can figure out
the problem.
| engine.openSession();
| JbpmContext jbpmContext = engine.getJbpmContext();
|
|
| TaskInstance taskInstance =
jbpmContext.getTaskInstance(taskInstanceId);
|
| if (map != null map.size() 0) {
| taskInstance.setVariables(map);
| }
|
|
| taskInstance.end(transition);
|
| engine.closeSession();
|
|
Is this code correct? is it usual to use it like this?
This only gives me problem's when the next node is a decision node.
thanks in advance

Ricardo, I'm no expert, but I'd be looking at your database and transaction configurations. What database are you using? It looks like you're running in Tomcat - yes? At the point that you're failing, you're probably opening a Job session for the first time. Jobs are interesting because they run on a different Hibernate session (and hence transaction and database connection) from the rest of JBPM. This probably has something to do with your problem - like for some reason I can't think of, you can't have two transactions open at once. On second thought... this is the only spot in the code that I see a session.getTransaction() call to Hibernate. You might look at the transaction-related properties in hibernate.cfg.xml and see if they make sense in your context. You might search around on them to get some guidance. -Ed View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4064970#4064970 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4064970 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

Here's my definition:

|decision name=decision
| transition name=to right to=right
| condition expression=#{ path == 'right' } /
| /transition
| transition name=to left to=left
| condition expression=#{ path == 'left' } /
| /transition
|/decision
|node name=left
| event type=node-enter
| action name=action1 class=actions.NotifyLeft/action

|node name=right
| event type=node-enter
| action name=action1 class=actions.NotifyRight/action
| /event
| transition name=from right to=end/transition
|/node
| /process-definition
|
When I come to task node and enter a value like right or left, I run a
TaskInstanceEndCommand to end the task and continue, when I do that the
considtino is evaluated and the correct node is called (which prints a line on
the console), then the Linkage Error pops up.
Debugging the application the error is raised on node.leave()
I'm trying to get a bit more detail where the error is raised, so clues and
hints are welcome meantime :)

Is it happening consistently? What is your environment? Can you describe this a bit more specific please?

apparently when i add a task to confinuar the problem vanish, still the error that jbpm gives in the absence of task's is a bit odd.

I'll change the schema to at least require 1 task as a child of task-node View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4063444#4063444 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4063444 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
