Hi, I'm using @Asynchronous on a SFSB and I get the expected behaviour. The current thread is not being blocked until the method completes. However, if I use a non HTTP client and a context lookup, then the active thread is actually being blocked, until the method finishes. So if use something like: | sfsb = (MySFSB) initialContext.lookup("/myApp/MySFSB/remote"); | sfsb.asychronousCall(); | then the call blocks the current thread.
