Apache and Tomcat URL parsing

[Jian Zhang <ji...@FLYINGCOLOR.com>]

Hello all:

I am wondering whether someone has come across this.

When apache passes the request URL to Tomcat, it seems that it replaces the
double bytes charactors with a empty string.
for example:  test.jsp?a=1&hello=*some japanese* 

in test.jsp
out.println(request.getParameter("a"));
out.println(request.getParameter("hello"));

The first out is fine. But the second output simply is nothing.

But it will all work fine only with tomcat alone.
Could someone explain this to me?

thanks for help.
