I tried the following handler, which seems straightforward: public class EndAllTasks implements ActionHandler { public void execute(ExecutionContext executionContext) throws Exception { executionContext.getTaskMgmtInstance().endAll(); } } but I'm getting a concurrent exception. I'm looking for a clean and simple solution. Thanks, Tomer View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4192046#...
