I have an error somewhere in this JSP code.
Any idea how to fix it?
I think I am missing some tags.

I have comments in the code to say what it is trying to do.

Thanks
<%
 
if (db2username == null) {
   // variable from http server does not exist
} 
%>
 
<%-- redirect the user to the login page --%>
<meta http-equiv="refresh" content="0; url=http://myUrl.com?app=CD">
 
<% } else { %>
 
<%-- if the variable is passed from the login page, then check if the cookie exist --%>
<%
Cookie[] cookies = request.getCookies();
for (int i=0; i<cookies.length; i++)
{
if (cookies[i].getName().equals("db2username"))
   {
%>
 
<% } else { %>
<%-- if the cookie does not exist, then create it --%>
<%  Cookie rdb2username = new Cookie("db2username",db2username);
	rdb2username.setMaxAge(2592000);
	response.addCookie(rdb2username);
%>
 
<% } %>
<% } %>

You need to tell us what the error is.

That said, I don't think the fragment you have posted will work the way you want.  And I assume it won't compile -- the fragment won't anyway.

You have a curly brace (})  on line 5 that probably shouldn't be there.  

If you remove that, then add an ending curly brace below line 30, then at least your code blocks are correct.

A Java IDE, or just a code editor with good syntax highlighting, would help you find problems like this one.  We have good luck with Eclipse, JEdit, Textpad, and the like.

Your first and biggest error is putting Java code inside  a JSP.
That's maintained for legacy/backwards compatibility reasons only. You should only ever use JSTL/EL in a JSP, and do whatever Java code you require in a servlet that afterwards forwards to that JSP for rendering.

It is not an error to have Java code in a JSP page.   There are some development frameworks which recommend what jwenting has said above.  There are others which don't.

Right -- as I said above, the curly brace at line 5 should be removed, and a closing brace added at line 30.
