I can't seem to get an ear file created with ANT (v1.1 or 1.3) to open in the reference implementation deploytool (version 1.2.1). I am using Windows 2000 and have tried both JDK 1.3.0-C and 1.3.1. I get a message window upon trying to open the ant-generated ear with File>Open Application in the deploytool GUI saying: "myapp.ear does not appear to be a valid application archive". Oddly enough, if I create an ear in the deploytool (which can subsequently be opened without a problem), extract its contents and then repackage those exact same files using ANT it still doesn't work. If I just use WinZip to zip up these same files and then rename the zip as an ear it works fine! Any help would be greatly appreciated. Marc
