serving japanese file problem

[Arun Prasad R]

i have a ウェブ.jpg (japanese filename) in images directory.
while requesting that file url encode to %E3%82%A6%E3%82%A7%E3%83%96.jpg

but tomcat doesn't serve ウェブ.jpg instead it says file not found.

my question is how to make tomcat to decode
%E3%82%A6%E3%82%A7%E3%83%96.jpg as ウェブ.jpg
