I found some code on jspin.com, exactly what im looking for, I changed a few things around as it was not compiling properly, due to some errors, now Im at a stage were there are no errors but Im not forwarded to success or the retry page, sorry about the long code guys, I really hope some one can help, it will be greatly appreciated

<%@ page import="java.util.*" %>
<jsp:useBean id="idHandler" class="foo.Login" scope="request">
<jsp:setProperty name="idHandler" property="idHandler"/>
</jsp:useBean>

<%
String arg1=request.getParameter("username");
String arg2=request.getParameter("password");
%>
<%
String username1=idHandler.getUsername(arg1);
String password1=idHandler.getPassword(arg2);
%>

<% 
   if (idHandler.authenticate(username, password)) {
%>
<jsp:forward page="success.jsp"/>
<%
   }  else {
%>
<jsp:forward page="retry.jsp"/>
<%
   }
%>

	   java.sql.PreparedStatement statement = connection.prepareStatement(query);
	   java.sql.ResultSet rst = statement.executeQuery();
