Starting Process Instance and Webapp
nib Jan 7, 2007 5:57 PMHi,
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.
