We bought some packages for enterprise Java Web application. These packages dosn't has source code. We met difficult in debug/trace of these package.

Is there some tool which can debug/trace Java program without source code? or the best tool to decompile class? We tried Dcafe, DJ, Jad, sourceagain. These decompilers doesn't support Jdk1.4/J2ee1.3.

    Decompilers aren't always necessary.  If you're trying to track problems with those packages, a profiler will probably do what you need.

    Try the Extensible Java Profiler:

    or JProfiler
