I should've been clearer, and said "you can use 'cygpath -p' to convert
*between* a POSIX-style path and a Win32-style one". "cygpath -[u]p" (the
"u" is optional) will convert from a Win32 path to a POSIX one, whereas
"cygpath -wp" will convert from a POSIX path to a Win32 one. For more
details, see "man cygpath", as Larry said.

What exactly didn't work here? What were the errors?

Nope. I haven't really had time to package them properly. I won't be
able to write full-fledged documentation, but I'm willing to answer
questions and accept documentation patches against the CVS repository
above. Care to help out?

They are wrappers around the "java", "javac", etc, executables. Just make
sure they precede the real executables in the PATH. They will basically
invoke the real ones, having translated the known path arguments to POSIX
format. They will not translate all arguments -- if you pass filenames to
your Java program, you're responsible for translating those. But they
help (a lot, actually -- I use them constantly on my machine).

They are wrapper programs written in bash.

Sure. You can run
/usr/local/bin/java -classpath /home/me/jars/a.jar:/home/me/classes SomeClass
And it'll call the Windows Java executable with the right paths.

You'll have to provide more details on what exactly didn't work in your
attempt.
HTH,
Igor
P.S. If you decide to try XJ after all, I'd be interested in your feedback
off-list.
