i got a simple class implementing the actionhandler.
but when i try to execute it i got
WaitAndSignal cannot be cast to org.jbpm.graph.def.ActionHandler
code is
|
| import org.jbpm.graph.def.ActionHandler;
| import org.jbpm.graph.exe.ExecutionContext;
|
|
| public class WaitAndSignal implements ActionHandler{
|
| private final static long serialVersionUID=1l;
|
| public void execute(ExecutionContext executionContext) throws
Exception {
| // TODO Auto-generated method stub
| try {
| System.out.println("Begin WaitAndSignal");
| long dauer = System.currentTimeMillis()% 100000;
| Thread.sleep(dauer);
| executionContext.getProcessInstance().signal();
| System.out.println("pid is = "
+executionContext.getProcessInstance().getId() );
| }
| catch(Exception e ) {
| e.printStackTrace();
| }
| System.out.println("end WaitAndSignal");
|
| }
|
| int wait =100;
|
| public int getWait() {
| return wait;
| }
|
| public void setWait(int wait) {
| this.wait = wait;
| }
|
| }
|
the processdefinition is
| <?xml version="1.0" encoding="UTF-8"?>
|
| <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="autokette">
|
|
| <start-state name="start-state1">
