Hi All,

    My Test.java source code is :

package org.test;

import org.activiti.engine.delegate.DelegateTask;
import org.activiti.engine.impl.pvm.delegate.TaskListener;



public class Test implements TaskListener {

public void notify(DelegateTask delegateTask) {
     delegateTask.setAssignee("fozzie");
   }
}


waiting your help .
Thanks.

Looks like you are using a TaskListener where a JavaDelegate is expected (in a service-task eg.). Can you post your process-definition as well?

Hi ,

   Thanks for your reply. I have work out the function .

Thanks again.

Evan.

Evan did not post his solution and I am having a similar problem.  The exception (listed first below) says that the class CreditChecker does not implement the org.activiti.engine.delegate.JavaDelegate interface.  The source code (shown below) shows the implementation (which Eclipse inline help resolves to the correct type).  I included the process definition (listed second below) for your reference.  Any suggestions?

Do you have multiple versions of activiti in your classpath? Is the activiti-jar in the same classloader as your own classes (eg. tomcat webapp lib vs. tomcat /lib)
