How to use request.setAttribute() in JSP?

[makpandian]

Hi,

I need to pass a string that s too long from JSP to servlet. What i did was I made one hidden variable and assign that sting in that variable. In servlet i use request.getParameter(). It worked perfectly. Since my string have had some special chars I was not able to request.getParameter.So I used session.setArrribute().NOw it works so fine. But instead of that I need to use request.setAttribute(). When I do this , I am getting NullPointerException in my servelt. Hope you understand Where I stuck. CAn we use req.setAttribute() in Jsp? If So, How.?

Can you do us a cutdown version of your problem?
The JSP, the Servlet, the call map (JSP -> client -> Servlet).
I'm trying to figure out what you're up to.

What's "too long"?
Where is the String coming from?
You aren't giving us much information to go on here.

[makpandian]

that string has 500 chars. It s created in JSP page depends on certain conditions. Did you get enough information.? if not I am ready to explain.

Now, lots of people get his terminology wrong.
By "created in JSP page" do you mean it is created on the server?
Can you show the code?
