Classloader problem
Hi All
I'm having trouble with the load of an assignment class,
this is the class
package br.com.glr.populis.model.workflow.common.handler;
import org.jbpm.graph.exe.ExecutionContext;
import org.jbpm.taskmgmt.def.AssignmentHandler;
import org.jbpm.taskmgmt.exe.Assignable;
public class PessoaAssignmentHandler implements AssignmentHandler {
public void assign(Assignable assignable, ExecutionContext executionContext) throws Exception {
assignable.setActorId("1");
}
}
processdefinition.xml
<?xml version="1.0" encoding="UTF-8"?> <process-definition name="teste-swinlane"> <swimlane name="pessoa"> <assignment class="br.com.glr.populis.model.workflow.common.handler.PessoaAssignmentHandler"/> </swimlane> <start-state name="start"> <transition name="tr1" to="task1"></transition> </start-state> <task-node name="task1"> <task name="task1" swimlane="pessoa"> </task> <transition name="tr1" to="node1"></transition> <transition name="tr2" to="node2"></transition> </task-node> <end-state name="end1"></end-state> <node name="node1"> <transition name="tr1" to="end1"></transition> </node> <node name="node2"> <transition name="tr1" to="end1"></transition> </node> </process-definition>

and this class is located in a EJB project and the jbpm jar is located in the application server lib directory.
My question is: Why jbpm put "classes" string at the begin of the class name? And if exists an alterante config to tell to jbpm to load classes using its own name?
i'm not using the class inside the .par archieve, couse i dont need it versioned and so more reasons!
i need to use the class inside the ejb!
how could i do this work fine?
Thanks
