I have written a code to get a list of taskinstances for a particular user using jpdl.

Exception : java.lang.reflect.UndeclaredThrowableException
Cause : java.io.InvalidClassException:

StackTrace : [Ljava.lang.StackTraceElement;@18ee9d6
The code is-
package com.sample.action;
import javax.rmi.*;
import javax.naming.*;
import org.jbpm.ejb.*;
import org.jbpm.command.*;
import org.jbpm.taskmgmt.exe.TaskInstance;
import java.util.List;
public class Test1
{
public static void main (String[] args)
{
String[] actors = {"Anuradhaps"};
try
{
Context c = new InitialContext();
Object o = c.lookup ("ejb/CommandServiceBean");
RemoteCommandServiceHome home
=(RemoteCommandServiceHome)PortableRemoteObject.narrow
(o,RemoteCommandServiceHome.class);
RemoteCommandService RemoteCommandService = home.create();
GetTaskListCommand command = new GetTaskListCommand(actors);
List result = (List) RemoteCommandService.execute(command);
if ( result.isEmpty())
{
System.out.println("List empty");
}
else
{
TaskInstance TaskInstance=null;
while(result.iterator().hasNext())
{
TaskInstance =(TaskInstance)result.iterator().next();
System.out.println("name of task : " + TaskInstance.getName());
}
}
}
catch(Exception e)
{
System.out.println("Exception : " +e.toString());
System.out.println("Cause : " +e.getCause());
System.out.println("StackTrace : " +e.getStackTrace());
System.out.println("Message : " +e.getMessage());
}
}
}
Please help me solve this issue.
