Can you tell us the exact version of Oracle WebLogic you are running (not the marketing name)? See this for more details:
By the way, it's actually LiveCycle with an 'e' instead of 'f' :-)
Our Application server is BEA WEBLOGIC 10.01 and is an older version of ORACLE WEBLOGIC 10.03.
So the question is: Is there any version of Adobe LiveCycle compatible with a BEA WEBLOGIC or Abobe Live Cycle works only with Oracle WebLogic ?
