Ant Script return code problem while using with shell script?

Hi i am currently working with mqfte. I use a shell script to invoke an ant script. In turn the ant invokes a transfer. In case of the transfer failure i need a return code 1 and 0 in case of success. For this i am using $? in my shell script after the ant invoking step. But in both cases i get a return code 1. what could be the problem with 开发者_如何学Gothis? the operating system used is unix.

Please edit your question to include minimal ant script AND the offending shell script. Otherwise it is too difficult to guess what is going on.

OR use set -vx to see the shell debug trace. you may see something happening that you don't expect.
