Subject: Servlet retains variable for each instance..???
> Hello all,
> Please go through this code to understand the problem
>
>
> public class testServlet extends HttpServlet{
>
> private String UserName=null;
>
> public void init()....{
> ...}
> public void doPost(..)..{
> {
> PrintWriter out=res.getWriter();
> out.println("First:"+UserName);
> ..
> ..
> UserName="somevalue";
> out.println("Second:"+UserName);
> }
> }
>
> When I run this Servlet ,output->First: null Second:somevalue
> Run this Servlet in another browser(second time), I got the output as ,
> First:somevalue Second:somevalue.
> How the old value is retained.Each time the servlet is called,it is
> initiated and so the First value should be null.
> Kindly let me know the reason for this behaviour.
>
> This I avoided by declaring the UserName inside the doPost method.
