So at what point are you storing the values from your login form into the bean? Because I don't see where you have done that.

I was curious about that as well, so how do I store them?

I did that but Tomcat gives me the following error:

From your Code the first two lines

<jsp:useBean id="login"...
<jsp:setProperty name="user"...

is not neccessary for your login.jsp page and there is a mistake there anyway. the id="login" should be the same with the name="login" as in:

<jsp:useBean id="login"...
<jsp:setProperty name="login"...

and not the way you used it. Take note.

As i was saying your login.jsp does not need the first two lines.

Now to your success.jsp page:

it should have some code similar to this at the top:

<jsp:useBean id='login' class='com.services.db.SqlConnect' scope='session'>
<jsp:setProperty name='login' property='userName' value='<%=request.getParameter("userName")%>'/>
<jsp:setProperty name='login' property='password' value='<%=request.getParameter("password")%>'/>
<jsp:useBean/>
<html>
...
.
.
.
</html>

if I were writing this I would be submitting to a servlet and not directly to a JSP.. anyways I hope this solves your problem
