[JBoss jBPM] - Re: Stateless Process Engine executor threading issues
by jorgemoralespou_2
Thanks Ronald,
But actually I pasted an old version of the code.
| try {
| // Fetch JbpmContext
| ctx = getJbpmConfiguration().createJbpmContext();
|
| // Get process definition
| ProcessDefinition processDefiniton = null;
| processDefiniton = ctx.getGraphSession()
| .findLatestProcessDefinition(processName);
| if (processDefiniton == null) {
| throw new ProcessDefinitionNotFoundException(processName);
| }
|
| // Create instace, add input params as context variables
| ProcessInstance instance = new ProcessInstance(processDefiniton);
| instance.getContextInstance().setTransientVariable(
| "REQUEST", req);
|
| // Execute process
| do{
| instance.getRootToken().signal();
| } while (!EndState.class.isAssignableFrom(instance.getRootToken().getNode().getClass()));
|
| // Get output parameters
| Map<String, Serializable> response = (Map<String, Serializable>) instance.getContextInstance().getTransientVariable("RESPONSE");
| return response;
| } catch (Exception e) {
| throw new JbpmEngineException("Unexpected error", e);
| } finally {
| if (ctx != null) {
| ctx.close();
| }
| }
| }
|
This code, as I think obtains a context, and signals every token in the execution path right through the end. I don get hold to a context.
I'm not sure if your answer is still aplicable. I'll try what you suggest though.
Also, is there any way of not using services like Messaging, Authentication and Logging? I've read that commenting the code in jbpm.cfg.xml should do the work, but it? actually doing all the work but persisting to database.

[JBoss Seam] - Seam Remoting Dependency?
by bsmithjj
Hello,
I just tried to upgrade my project to Seam 1.2.0 (PATCH) - I got this:

does this mean that Seam core requires seam remoting? if so, why put them in separate jars?
Thanks,
