Building Limewire with Eclipse

Hello,

I'm using Eclipse 3.1.1 to build and run Limewire 4.9, but am having difficulty. I have successfully built the core and gui modules, but when I try to fire up the limewire startup script "run.bat", I get what seems to be a classpath related error. Does anyone know how to fix this? Here's the error that displays on my console after executing run.bat:
