WebLogic Tuxedo Control - TPESVCFAIL errors

Question

Hi,
I am trying to invoke a tux service from WebLogic. In a success scenario, this works well, although when the tux service returns a TPFAIL with a TPESVCFAIL, it seems like I cannot access the return buffer when my process throws the exception...
is it possible for me to do this? get the reply buffer when the process throws this specific exception? The buffer returned contains error messages required in the WLI Process.
The other way I thought of doing it is using the getConnection() method in the Tuxedo Control, to establish a connection, then manually perform a TPCall to the service, and read the buffer and return the information when I receive the TPESVCFAIL. Should I even look at this option? The error i get in the Tuxedo ULOG when i attempt to do it this way is: LIBGW_CAT:1029: ERROR: Service request not forwarded to remote site:"TPETIME - timeout occured" gwerrno(402017)

Hi,
It is possible to get the reply buffer from the exception. The ControlException will contain the TPReplyException. Use the getNestedException() method on the ControlException and make sure it's an instance of TPReplyException. Then you can then use the getExceptionReply() method on the TPReplyException instance to get the reply buffer. But you will need to process the reply yourself, i.e., fall back to JATMI calls to pick apart the Reply instance.
There is a enhancement CR already filed against the control to have it provide its own exception type that would include the deserialized return type in the cases where a reply buffer was provided. This was simply a case I didn't consider, sigh.
