I have a WAR file for my struts app that I created from the JRE command line with the 'jar' command. I then created an EAR file with the Application Assembly tool in Websphere Application Server 4.0, then deployed to WAS 4.0. My struts app was developed with Visual Age for Java 4.0 and tested with Tomcat. I now want to test with WAS 4.0 running on Win2K, then once that works, will deploy to WAS 4.x on ZOS. While testing with WAS 4.0 I got null pointer exceptions in areas of the code that worked fine with Tomcat. So now it looks like I need a debugger to test with WAS so I can step through the code and find out why the null pointer exceptions. For this purpose, I installed Websphere Studio 4.0 with the debugging tool. The question is does anyone know if I can turn my WAR file into an application on Studio? In other words is there a way to 'reverse engineer' a WAR file into an application that can be debugged? The option of using Websphere Application Server from within VAJ is always there I suppose, but that's WAS 3.5.3 and I specifically want to use WAS 4.x. Thanks in advance. Jane
