Re: session timeout not working anymore :(

2003-02-04 Thread Sean Dockery 
What used to worked?  What behavior are you expecting that you no longer 
observe?

If I was to guess at what you're expecting to happen...  I would guess that 
you are expecting that getSession(false) would equal null at some point and 
that never happens?  This causes the useBean directive to fail.

Try including a page directive for the JSP page not to participate in 
sessions.  That is, insert the page directive before the DOCTYPE line.

<%@ page session="false" %>

If not otherwise instructed the JSP compiler will automatically create a 
new HttpSession object for you by inserting the call HttpSession = 
request.getSession(true) into your compiled JSP code.  Unless you suppress 
this behavior, your test in header-inc.jsp will always fail.

At 23:35 2003-02-04 -0500, you wrote:

Sigh. We used to have a piece of code included in our jsp's like so:
header-inc
<% if (request.getSession(false) == null) { %>
   
<% } %>

header-inc
and that was included in our files like so. That used to work.. but
now when I have struts-html and struts-bean.. it always fails.
Is there something wrong with getSession(false) now?

The stack doesn't seem to include the struts generated servlets.. so
I'm really puzzled!!

Any help will be much appreciated even if it's only to say.. "it's not
struts" :)

I'm running Tomcat 4.18 on Windows XP.
Thanks.

That's the right answer :-).  The exception is not happening in Struts, it
is happening inside your page.

This is the key to the problem -- for some reason, the page is not able to
create an instance of your "com.ascent.webapps.common.User" class.  Why it
is even trying to do so must be in some code you have not shown us yet,
but the most common causes are:

* You don't have a copy of this class visible to the webapp.

* The class is not public.

* The class does not have a public, no-args constructor.

* Somewhere in the constructor, or one of the initialization
  expressions for your class's instance variables, an exception
  is getting thrown.

I admit not not looking at this in detail.  But the lack or a 'return;'
statement after the jsp:forward is a major red flag.
