Hi,
I wish to save value entered by user in textbox in a session variable.my form contains many elements and i need to navigate back and forth.so i want to save the value once entered by the user in a session variable so that i can retrieve it and display on navigating back.i know session.setAttribute("varname",stringvalue);
saves stringvalue in varname but how do i get textbox value as a string on the page and save it there?request.getParameter does not work on the same page.
Thanks

Jump to Postrequest.getParameter works just fine. You shouldn't use it of course as you should NEVER use any Java code on a JSP, but it does work.
Jump to PostJSPs are for presentation purposes only, not processing data.
They're also designed to be able to be maintained by non-programmers, people who don't know Java.
So they get presented with a set of tags (JSTL for example) that looks familiar to them.
Jump to Posthave you even bothered to read the entire thread?
Probably not, as you'd have learned not to do what you suggested.

hi there have you tried this:
<%session.setAttribute("[I]varname[/I]", request.getParameter([I]Textboxname[/I]));%>

I am quite new to JSP JWenting, I am intrigued, why is java code on JSP frowned upon?

<input type="textbox" name="AQC2_SOURCE_FILENAME" value="" />
<%session.setAttribute("srcfilename", request.getParameter("AQC2_SOURCE_FILENAME"));
String str=(String)session.getAttribute("srcfilename");
System.out.println("file name is***** "+str);
%>the code above gives str value as null.
what else can i do so that textbox value once entered remains after navigation as well.thanks

I'm sorry for that but was just trying to say that it does not work.Also if you bother to read the entire thread I last posted then you'd see that I did ask for a different way to solve the problem.
