unable to send huge data from jsp to servlet using doPost

[saikrishna cinux]

I am using post method for sending some data from jsp to servlet but it takes only 2K of data and moreover for postmethod the browser should not display the content in url
what might be the problem
here is the code i am using in the jsp page

document.forms[formName].method = "post";
document.forms[formName].action = url+qncontent;
document.forms[formName].submit();

thanking u

You're using the post method but it still looks like you're sending the data in the query string.
Why don't you send it in the post body?

Also, this is not an example of sending data from a JSP to a Servlet.
You're sending data from the browser to the servlet.

There is a limit to how large a query string can be.
It used to be 255 chars, but some browsers will now take more.

Merely specifying that the method is 'post' isn't going to help if you are still embedding the data in the query string.

If you have to build up the name/value pairs with javascript, create hidden input fields, add them to the form, populate them, and then submit the form.
Doing it this way will cause the data to be placed in the body of the post rather than the query string. You won't have to deal with the size constraints and (as a plus) all the data won't show up in the address bar of your browser.

If you need help, with the Javascript, let me know and I'll move this thread to the HTML/Javascript forum.

You could use AJAX.
If you need help/examples, of this, let me know and I'll move this thread to the HTML/Javascript forum where the AJAX gurus hang out.
