I have a Message Driven Bean for controlling the processes. I need some information about the running processes, wich process/tokens is in waiting state, where can i signal the process to resume executions. What is the pattern if i want to create a processManaggerMDB that can - start the process (this part is ok :)) - create a list from waiting process ( i need to create a task for every resumable tokens?) -signaling (i want to take a signal for the tokens to resume the process executions. Need i lock the processInstace prevent from the Paralel executions that can occure hibernate exception, and unlock when the executor finished - the process finished or entered a new wait state.- thx, Janos View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4188768#...
