Hi I have following problem. I build a webservice wich sends a JMS Message to ESB an then the ESB starts the Process. Now the Process gather information. In the end the process sends a JMS Message back to the Webservice with the result. Now the Webservice responce the result to the sender. While gathering information the process is able to call webservices. Here I need to request my own webservice. Now the ESB starts want to start the process again. But the process do not start. After a while the Node in the "Parent-Process" which is waiting for answer from the Webservice goes to "fail" node and is persistent. Now the "Child-Process" starts working. What is the reason for that? Is it because the is only one Process Executer. When one process instance is persistent he can switch to another? In that way more processes never really work parallel, right? Is there any way to solve this Problem? Like starting more Process Executors in any way? Thanks for help.
