Hi Keven,
A trick for young players is that you may not have put
in the line for the logic tags at the top of your jsp.
Check you have this:
<%@ taglib uri="/WEB-INF/struts-logic.tld"
prefix="logic" %>
If you do in fact have this, and you have the ability
to set break points in your Struts code, I'd put one
in the PresentTag.condition(boolean) method and see if
it is getting hit, and whether it is evaluating
properly.
Also make sure that your String User does actually
equal "user" if you intend to look it up in the
session.
That's all I can think of.
