Can not get parameters from POST form on Tomcat server.

[Tran Hung Nguyen]

Dear All,

I have a problem with my tomcat server on Linux:
I have a java class named Exception.java. It will set some attributes to request when exception occur. And will display error.jsp with the parameters.
On my localhost, everything is okay. But when I deploy to Tomcat server. It cannot get parameters from request (return null).
If I set in session then it is okay.
My project use Struts and Spring to manage navigation.

Anyone have any ideas about this issue? Please help.
Many Thanks for your time,
