my scenario: On request (async) from GUI, workflow need to executed, Workflow should should have different simultaneous flow , in which , each flow should do independent work (it may need to wait on conditions, optionally between them for sequential execution- (if needed)) For this case, i wanted first decide, can i use threads / process And if decided, then i need to see how much threads / processes can be spawned / forked please say me if i am not clear in the above explanation. P.S: actually i am evaluating workflows , can ypu plz say , which workflow is better thanks, Arunachalam View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4187934#...
