I am assuming somethings here... if I am wrong... disregard
ASSUMPTIONS:
1. the usebean is in ur jsp A which has a form which submits a request
2. the the request is posted to a controller... say a servlet B.
now taking the http action into account a new request object is created when
u do a post or a get operation.... so by the time when u post to the
controller the bean has lost its instance...
if u did something like this..
<code>
<jsp:usebean scope="request"...../>
//then
//forward to the servlet...... the request scope remains.... else it is lost
//for ex.
request.sendRedirect("/B");
</code>
REMEMBER>>>>>a request scope is lost
1. after u send a response back.
2. u dont forward the request forward.
Hope that helps

Subject: Basic jsp:useBean question
Hi,
if I use the following tag in my jsp:
<jsp:useBean id="myBean" scope="request" class="package.name.myBean" />
When I click on the submit button on my form, the 'request'
is POSTED to a 'controller' jsp, which passes the 'request' onto a
request handler class.
I expected that if I called request.getAttribute("myBean") from either
the controller jsp or the request handler class, I would get the myBean
instance created by the useBean tag above. But I always get null??
thanks
Joel
