UTF8 support on linux installations - Very Urgent!!

I have installed LCES2 in linux 5.0

JBoss version is 4.2.1

Linux's default locale is en-US.utf8

liberation fonts are already installed.

But when i submit form to the server, the Arabic characters are converted into question (?) marks.

JAVA_OPTS is set to Dfile.encoding = utf8 as well.

MySQL also with UTF8 as default character set and UTF8_GENERAL_CI collation.

I dono what else to do. Plase help me. Its very urgent.
