Doing the above would result in a error of duplicate variable names.
Actually, I've gotten over this hurdle by making the authenticate.jsp as follows.
<html>
<%! LoginBean formHandler; %>
<%
formHandler = (LoginBean)session.getValue("loginBean");
if ( null!=formHandler)
formHandler.processRequest();
else
System.out.println("null handlerBean in request");
%>
<%@ include file ="/jsp/login/login.jsp" %>
</html>
The challenge now is in returning to the original login.jsp as indicated in
the <%@ include file = ...> tag. That part isn't working right.
Any suggestions out there?
