Subject: how to: xboard & java chess engine

Hi all,

I am writting my own chess engine in Java and I would like to use xboard with.

I launch xboard from xterm as follows:
/sw/bin/xboard -fcp "java -jar /users/denis/engine.jar" -debug

However, whatever I play (e4, d4, ...), my engine replies as expected and a
crash always occurs after my second move.

Below an extract of the log...
<i>
xboard: Error: first chess program (java -jar /users/denis/engine.jar)
exited unexpectedly
GameEnds(0, (null), 2)
Interrupting first
139155 >first : force
xboard: Error writing to first chess program: Broken pipe
GameEnds(0, (null), 2)
146409 >first : quit
</i>

Thanks for your help.
Best regards
Denis
