BTW: for the external launch: it's good to evaluate "1+1" or something=20
like that first, to start the remote JVM. This takes a bit (a couple of=20
seconds), so just executing something simple is best; after the console=20

something like print("Hello"); to see if it works.

Yes, that should be about right, but they shouldn't be problems (I just=20
log them for completeness). The first one comes from the fact that I=20
want to execute something, but the newly launched JVM (with Beanshell)=20
hasn't managed to start the RMI server yet.
With the 2nd one, it tries to send a Beanshell Callstack over the wire,=20
which isn't possible; Did an Exception or an error occur in the=20
Beanshell JVM?

What happens now if you launch the external mode?

But besides the error, is it possible to evaluate code?

you can get around this issue by setting the variable 'bsh.cwd' directly.

Thanks for the tip! The fact that the backslashes on windows cause=20
troubles, when the Beanshell interpreter sees them in Strings is really=20
a nasty little bug. I now set the bsh.cwd directory, and later on still=20
try the Beanshell cd();


Thanks for your bug reports, they're very helpful. Sorry if some things=20
don't work quite right yet, but with reports like these, I can try=20
fixing them.
