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 seem
to work because the LOGOFF button is still displayed.
<logic:notPresent name="user">
<html:link forward="logon">LOGON</html:link>
</logic:notPresent>
<logic:present name="user">|
<html:link forward="exit">LOGOUT</html:link>
</logic:present>
