On my personal Mac I could see Chinese characters rendered correctly on Web Page
But when the application is deployed on a server it was showing garbled chars like below
In my case.. my server provider had done some recent security upgrade. So my production web app was displaying chinese characters before the upgrade.
In any case, the responsibility was with me to fix this issue permanently
The solution was to add the below utf8 encoding params to Jboss startup script : run.conf
JAVA_OPTS=”$JAVA_OPTS -Dfile.encoding=utf-8 -Dsun.jnu.encoding=utf-8″
Once I restarted my production jboss with the above settings the application displayed chinese characters correctly!
Tested on jboss version 5.1.0

Note: THis tip is only for java applications running on top of Jboss. I haven’t figured out how to display chinese characters in jboss logs and mysql client
