[jsword-devel] webstart

[DM Smith]

I have dl svn from their website and have checked out the flashcard files.

I also tried subeclipse, but it did not work. It was missing a required 
dll (libapr.dll, apache portable runtime). They know of the problem and 
are working on fixing it. So, still no SVN from within Eclipse.

Troy, it looks like you have built the project w/ a gui builder/ide. If 
so, which one did you use?
