Have you also created a 'tmp' directory inside your webapp? (Think someone else pointed out this trick. But I'm not sure if this was related)

I already created a tmp directory in application directory, to solve thre problem that can't attach large file in post. This seems has nothing to with this problem.

Thanks a lot for your patience, Lazee! I guess I didn't add the headless parameter right. This time, I added the following line in catalina.sh,

CATALINA_OPTS="-Djava.awt.headless=true"

It's working now!
