Yes, you're right - it didn't have 'src' in the path. Should it - is that a bug
- can we assume that an automake project will always have a src directory? You
can't put 'src/ScribbleWindow' in the gideonprj file, it didn't get parsed. In
jdbcontroller, I stripped off the path and and just ran a 'jdb ScribbleWindow'
command, relying on the $CLASSPATH to be set up for the 'src' directory. I
think it should strip off the directory path and add that to the contents of
$CLASSPATH, then pass that as a '-classpath' parameter to jdb.

Hmm... I wouldn't say that, I've been trying to do Objective-C for about the
last year, I've only got sidetracked into doing Java stuff. The language does
appear to have potential though :-)  And I think Oliver is on the case now...

Yes, I agree you have the same problem with '.' in both $PATH and $CLASSPATH.

.class files could be built into the .libs directory - there is a JAVAROOT make
variable (currently '.') - would that be a good idea? I don't know if there is a
standard KDE install directory hierarchy for installing java .class files, but
that would also be useful.
