Send large amount of text to servlet via form

Question

I'm working on Java Servlet. I have form on my jsp file and I am sending huge amount of text from form to servlet it sends to servlet successfully but, I can't get any parameters from request object get parameters are always null on my servlet class, if I send less amount of text when pass to servlet working perfectly. I don't know how to solve this problem. Can you know this problem solution help me. I will appreciate your effect.

Huge amount of text count. It's above 50,000

is that you have used larger text in a single parameter or too many parameters... — Prakash, Mar 26 '14 at 07:50

Edit Tomcat's server.xml. In the element, add an attribute maxPostSize and set a larger value (in bytes) to increase the limit. if maxPostSize="0" it means it is unlimited..

You should check your tomcat version, if bigger than 7 maxPostSize="0" will not effect, setting maxPostSize="-1" is ok.
