If you are implementing the TraversalJ project on Windows platform, then
read this message; otherwise, just ignore it.

When working on Windows platform while using AspectJ compiler in DemeterJ,
there are two things you should pay attention to:

  1. the COMPILER setup in the .prj file should be

     COMPILER = ajc.bat

     not just

     COMPILER = ajc

  2. You should go to the AspectJ web site ( to
     download and installthe most updated version of AspectJ compiler (1.1a1),
     which is newer than the current version available from CCS's UNIX

I believe Harry's problem comes from a bug of AspectJ 1.0.6 ( I think
you are using this version, right, Harry?). AspectJ 1.0.6 compiler doesn't
recognize the CLASSPATH separator ';' on Windows platform. 1.1a1 version
doesn't have this problem.
