I have an index.jsp page that checks a user's access level:
<%@ page language="java" errorPage="" %>
<%
String userid = (String)session.getAttribute("UserId");
if (userid == null) {
pageContext.forward("login.jsp");
} else {
String access = (String)session.getAttribute("Access");
switch (access.charAt(0)) {
case 'A':
pageContext.forward("admin/index.jsp");
case 'R': case 'W':
pageContext.forward("db/index.jsp");
default:
pageContext.forward("login.jsp");
}
}
%>
And yet the above page works even with the <%@ page language="java" %>
line. I don't understand why the above code works but the doesn't work
for another page.
What do you propose -- that I remove the <%@ page... %> line?

Yep, looks ugly.
What is even worse is code that sends a redirect and does NOT do a return.

Subject: Cannot forward after response has been committed
I have a jsp page that processes a login. The (simplified) code is
something like this:
<%@ page language="java"%>
<%
String userid = request.getParameter("userid");
String pw = request.getParameter("pw");
/* code to check user id and password */
if (user not found)
pageContext.forward("login.jsp");
else
pageContext.forward("userpage.jsp");
%>
Please note that nowhere in my jsp code do I use the "out" object or
send some outputs back to the client. Yet, I am getting this "Cannot
forward after response has been committed" error. If I comment out the
forward statements then the error disappears. Any help is appreciated.
