Delegation Class Problems (Repost)
I have desgined a very small workflow using eclipse. I have incorporated an assignment class to delegate a task to a particular user. All micky mouse stuff but I am getting the following in JBOSS log
ERROR [Delegation] couldn't load delegation class ''
and this from the web page :-
Error starting process: An exception of type "org.jbpm.graph.def.DelegationException" was thrown.
Now this is my processdefinition.xml
<?xml version="1.0" encoding="UTF-8"?> <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="IT01"> <swimlane name="initiator"> <assignment class=""></assignment> </swimlane> <swimlane name="ITManager"> <assignment class=""></assignment> </swimlane> <start-state name="start"> <transition name="transition1" to="getDetails"></transition> </start-state> <end-state name="end"></end-state> <task-node name="getDetails"> <task name="getDetails" swimlane="initiator"></task> <transition name="Transition2" to="Check Form"> </transition> </task-node> <task-node name="Check Form"> <task name="ITManagerFormCheck"> <assignment class="uk.gov.torbay.it01.jbpm.ITManagerAssignment"> <actor>manager</actor> </assignment> </task> <transition name="Transition3" to="end"></transition> </task-node> </process-definition>
and this is the source of my uk.gov.torbay.it01.jbpm.ITManager Assignment class.
package uk.gov.torbay.it01.jbpm;
import org.jbpm.graph.exe.*;
import org.jbpm.taskmgmt.def.*;
import org.jbpm.taskmgmt.exe.Assignable;
public class ITManagerAssignment implements AssignmentHandler {
private static final long serialVersionUID = 1L;
private String actor;
public ITManagerAssignment()
{
}
public void assign(Assignable assignable, ExecutionContext executionContext) {
assignable.setActorId("manager");
}
public String getActor() {
return actor;
}
public void setActor(String actor) {
this.actor = actor;
}
}
From the above error It would appear I have a parsing problem with the processdefinition.xml file since it seems to be trying to load a null class path/name.
Anyone got any ideas where I am going wrong here ?
The Eclipse deploy seems to indicate everything is ok so I am not sure whate to believe here.
Appologies for repost I quoted the code instead of coding it and it didnt like it, price you pay for not previewing things in the first place.
