Mr. Ford, My Logic Tag Does Not Seem to Work

[JiaPei Jen]

Please point out my mistakes. Does the 'name' attribute of the logic tag accept an object only? For example, I created a session this way:

HttpSession session = request.getSession();
String username = request.getRemoteUser();
session.setAttribute( "user", username );

In the LogoffAction, I invalidate the session and want
to forward the visitor to the welcome page. This is
what I did:

HttpSession session = request.getSession(false);
String username = (String)session.getAttribute( "user" );
if (username != null) 
{
   session.removeAttribute( "user" );
   session.invalidate();
   return (mapping.findForward( "success" ));
}

I used the logic tag in my welcome.jsp. It does not seem to work because the LOGOUT button is still displayed.

<logic:notPresent name="user">
<html:link forward="logon">LOGON</html:link> 
</logic:notPresent>
<logic :-P	 resent name="user">| 
<html:link forward="exit">LOGOUT</html:link>
</logic :-P	 resent>

Not sure off hand -- I don't see anything wrong in the code you posted. You should check the session in a debugger to make sure that the value is actually removed when it gets back to the JSP. Note that, if you use a useBean tag at the top, it automatically creates the bean for you, which may be the problem.
