Hello,
At the creation of the knowledge session I use this code to register my usergroupcallback :
// By Setting the jbpm.usergroup.callback property with the call
// back class full name, task service will use this to validate the
// user/group exists and its permissions are ok.
InputStream usergroupsin = KnowledgeSessionProducer.class.getResourceAsStream( "/jbpm.usergroup.callback.properties" );
if(usergroupsin != null) {
Properties callbackproperties = new Properties();
try {
callbackproperties.load(usergroupsin);
UserGroupCallbackManager.getInstance().setCallbackFromProperties(callbackproperties);
log.debug("Task service registered usergroup callback ...");
} catch (Exception e) {
log.debug("Task service unable to register usergroup callback ...");
}
}
if(UserGroupCallbackManager.getInstance().existsCallback()){
System.out.println("userGroupCallBack exists ! :)");
}else{
System.out.println("userGroupCallBack don't exist ! :(");
}
and I create a file name : jbpm.usergroup.callback.properties in src/main/resources
that contain this line :
jbpm.usergroup.callback=com.st.ams.task.management.AMSUserGroupCallbackImpl
This is the associated log :
17:06:45,137 DEBUG [com.st.ams.jbpm.knowledge.KnowledgeSessionProducer] (http--127.0.0.1-8080-3) init of KnowledgeSessionProducer ...

I hope it will help you.
