<br/>
<span class="style3">Click <a href="LogIn.jsp">here</a> to re-login.</span>
<%
} else {
out.println("Welcome " + userName + "!");
}
%>
our problem is with the validation. We got a wrong output. If we put anything (even the 'Jose' username) we have the invalid message...
what's wrong with our code? can someone checked on it...
Thanks in advance.
