According to eclipse error log and programmer forum, there's an error with the "ant build". Currently trying to understand what this means. The linux version installs and runs, but doesn't operate fully, due to database connection configuration, I think. Further investigation has found that database connection is successful with "localhost", but not "127.0.0.1" which is identical?
Anyway, withdrawn my mistaken claim that the project is designed for use with windows; a more accurate description is that documentation is only biased towards windows usage; linux users need to do a bit more work!
It would be nice to be able to change database though, e.g. to choose postgresql or even an xml database.
