Thanks for the suggestion shraddha294.

In my Ant script (shown above in this thread), I actually am calling jdwp.bat in my debug target.

In my simulate target is where I was calling 8120.bat. At the moment I don't really care about the simulate target.

But I may have discovered part (or most) of the problem. Eclipse was not using my Ant script to build or to run the debugger. I now have Eclipse using it for building (having added a custom Builder). I can not yet get Eclipse to use the Ant script for debugging. I'm using the Ant Viewer and am trying to run my debug target from that viewer, but it is not being called. I've posted to an Eclipse newsgroup about that issue.

Finally I have a problem with displaying String variables in the Eclipse debugger, but I'll put that in a separate post in this forum.

Thanks,
Paul
