Delegation Class Problems

[tombrough]

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.
