Symptom

  • Upon completing the last step of configuring new event action handler wizard, CPE ACCE displays error "Unable to load event handler class from either associated code module or system classpath: com.ibm.filenet.edu.SampleActionHandler".
  • The class com.ibm.filenet.edu.SampleActionHandler is verified to exist in the provided code module .class file. The Java source code contains:

    package com.ibm.filenet.edu;
    public class SampleActionHandler implements EventActionHandler {

Resolving The Problem

Set the Java compatibility level down to 1.6 instead of 1.7 or 1.8.
