JDE compile server and ant server problem

[address@hidden]

I use ntemacs22,jde to develop java application,when I compile the source
It seems the encoding is wrong,the compile server's
output looks like the following.

-classpath d:/home/lu/build -g d:/soft/emacs-22.1/bin/Test.java
d:/soft/emacs-22.1/bin/Test.java:3: <identifier> \202\302\252........

My Os is windows xp(japanese language)
what's the problem.

by the way,it is no problem on linux(utf8)

Thanks.
