IllegalStateException using other libraries

Hi all,

I'm new to robocode, trying to use it for an art project of all
things. I've got the source downloaded and a project set up in
eclipse, as I want to interface with another project. Everything
compiles fine, I get both projects starting up when I try to run.
However, I want my robot to reference the outside project, and that's
where things are falling apart for me. The robot either doesn't load
(sits there saying "Disabled"), or it doesn't load and I get an
IllegalStateException -- it depends upon where I tried putting the
libraries (in the robots directory, or in the main project directory).
I'm not sure what else to try. Both projects are in Java, so I was
hoping to make use of that instead of having to resort to
reading/writing a file to communicate between projects. Any ideas?

Thanks,
Rebecca
