Hi all ,

I am getting this error every time i try to make a new instance of BPEL process using java API .

The error is thrown on when I do a post using "deliveryService.post("UserTaskSample", "4.0", "initiate", nm);"


An exception has occured : java.lang.Exception: Failed to create "ejb/collaxa/system/DeliveryBean" bean; exception reported is: "javax.naming.NamingException: Lookup error:
