Hi all,
I have written an EJB to call LiveCycle Forms and LiveCycle Reader Extensions to do the form rendering and then RES the rendered form and then write a Web Service to wrap the EJB. I found that if there are more than 30 threads to call the Web Service, there will be thrown either RemoteException or ConcurrentModificationException (Error must be occurred in 40 threads). I have tried to configure the Pool Max for RES but the same issue is also occurred. Do anybody knows how to fix it? Here are the snap shot of log.
