The IWorklistMonitor service provider interface can be used execute custom code when item are added to or removed from a workflow participant's worklist. Typically this SPI is used to implement push notification to users (UI alerts, email, ...) or other systems.

To use this interface you need to:

  1. Implement the IWorklistMonitor interface as shown below.
  2. Create a text file named org.eclipse.stardust.engine.core.spi.monitoring.IWorklistMonitor. The file contents needs to be the fully qualified name of your implementation class, e.g. org.eclipse.stardust.example.WorklistInterceptor .
  3. Place the file into the META-INF/services folder of the jar that will contain your implementation class
Use this interface with caution! We do not recommend to use this functionality to constantly synchronize the worklists into another system. To maintain the worklists in two systems is a bad architectural design typically resulting from shortcuts taken. It usually leads to problems further down the road.

package org.eclipse.stardust.example;
 
import org.eclipse.stardust.engine.api.model.IParticipant;
import org.eclipse.stardust.engine.core.runtime.beans.IActivityInstance;
import org.eclipse.stardust.engine.core.spi.monitoring.IWorklistMonitor;
 
public class WorklistInterceptor implements IWorklistMonitor {
 
    @Override
    public void addedToWorklist(IParticipant arg0, IActivityInstance arg1) {
	System.out.println("ADDED TO WORKLIST: " + arg0.getId() + " Activity OID: " + arg1.getOID());
 
    }
 
    @Override
    public void removedFromWorklist(IParticipant arg0, IActivityInstance arg1) {
	System.out.println("REMOVED FROM WORKLIST: " + arg0.getId() + " Activity OID: "+ arg1.getOID());
    }
 
}
