It's strange that there's no encoding problem in jboss4.0.2 but there is
in idm-jboss.

I use the javascript function encodeURIComponent(str) to pass the
parameters and with several page-encoding settings and it's ok in
jboss4.0.2.

But when I deploy and customize the module on idm-jboss, it can't
recognize my non-English input in the servlet but normal when I alert(str).

Anybody has research in this area?

Thanks in advance!
