I have a query........Suppose like in normal sites like gmail and yahoo where they have username password entry............suppose a user enters the username and password.......then the server checks from the database whether the username password pair matches and if it does automatically redirects to another page and if it doen't match then redirects to another page.......Can we achieve this using JSP
I have structured a program where the user enters the username and password and the program checks from the database to see if the username and password pair matches and if so then returns true else returns false
But I can't manage to make the program redirect to another page when the username and password pair does match!

I have been able to do it..........something like this:
where users is the name of the bean I have used!!!
Just wanted to know whether this is the right way to it or not??? Is there any other alternate way?

Not really, there are several problems with the code.
Firstly, -assuming that "users.getVal()" returns a string- note that string equality is checked via the String.equals method, not via the "==" operator; that will cause problems.
Secondly, you really shouldn't keep code that controls the application flow in a JSP. Actually, you should not keep any Java code in JSPs. That has been a bad practice for many years now. Put such code in a servlet.
Lastly, it looks as if you're trying to redirect the browser to some external URL. You should do that on the server via HttpServletResponse.sendRedirect(...).
