Should be CommandBasedWSHumanTaskHandler

It could be

ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new WSHumanTaskHandler());

or

ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new CommandBasedWSHumanTaskHandler( ksession ));

You should use CommandBasedWSHumanTaskHandler if you want to persist HT activities.

Just a minor correction, you should use

ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new CommandBasedWSHumanTaskHandler( ksession ));

If you are persisting your ksessions, not your Human Task Activities.

Usually you will persist the HT activities if you are using a Mina Server or the hornetQ Server.

you are right i have expressed wrong the concept
