[jboss-user] [JBoss jBPM] - Starting Process Instance and Webapp
Hi,
I start an process instance from a mdb via the following code:
| private void kickOffProcess(String processname, String [] attrnames,
java.io.Serializable[] attrvalues) {
| try {
| // Logging
| log.info("!!! MDB: KickOff "+processname);
| for (int i=0;i<attrnames.length;i++)
| log.info("!!! MDB: Parameter "+attrnames);
|
| log.info("!!! MDB: Initialisize jBPM");
| org.jbpm.JbpmConfiguration jbpmConfiguration =
org.jbpm.JbpmConfiguration.parseXmlString(
| "<jbpm-configuration>" +
|
| // A jbpm-context mechanism separates the jbpm core
| // engine from the services that jbpm uses from
| // the environment.
|
| " <jbpm-context>" +
| " <service name='persistence' " +
| "
factory='org.jbpm.persistence.db.DbPersistenceServiceFactory' />" +
| " </jbpm-context>" +
|
| // Also all the resource files that are used by jbpm are
| // referenced from the jbpm.cfg.xml
|
| " <string name='resource.hibernate.cfg.xml' " +
| " value='config/hibernate.cfg.xml' />" +
| "</jbpm-configuration>"
| );
| org.jbpm.JbpmContext jbpmcontext =jbpmConfiguration.createJbpmContext();
|
|
| log.info("!!! MDB: Create Instance");
|
|
| org.jbpm.graph.exe.ProcessInstance pi = jbpmcontext.newProcessInstance(processname);
|
| log.info("!!! MDB: Set Parameter");
| for (int i=0;i<attrnames.length;i++)
| pi.getContextInstance().setVariable(attrnames,attrvalues);
| log.info("!!! MDB: Signall");
| pi.signal();
| log.info("!!! MDB: Signal");
| jbpmcontext.close();
|
| } catch (Exception ex) {
| log.info("!!! ERROR MDB: Unknown Exception. Reason: "+ex);
| ex.printStackTrace();
| }
|
|
| }
|
|
|
| }
|
It starts the process and tasks are assigend to the user "ernie" (according to
the log).
| DEBUG [GraphElement] event 'task-create' on 'Task(Check Customer)' for
'Token(/customer)'
| DEBUG [TaskInstance] assigning task 'Check Customer' to 'ernie'
The task-code
| <swimlane name="Worker">
| <assignment expression="user(ernie)"></assignment>
| </swimlane>
|
| [..]
|
| <task-node name="Check Customer">
| <task swimlane="Worker">
| </task>
| <transition name="Check done"
to="join1"></transition>
| </task-node>
|
|
The Problem is: In the Webapp (jBPM 3.2 alpha 2) it does not appear on ernies tasklist.
Don't know whats wrong.
