Hello Gary,
If you want to create an instance of a bean within a servlet, and then use
the request object to forward it to a jsp page, you have to extract it from
the request object within the jsp page, like this:
<%@ page session="true"% import="BeanClass">
<%
BeanClass the_bean = (BeanClass)request.getAttribute(beanName);
%>
Hope this helps,

Subject: Accessing a 'bean' from both servlet and jsp
Gary Albers@TIMEWEB

Hi Folks,
Is there any special 'trick' to being able to access an object (bean) from
within a
servlet and a jsp page? I am not getting the same instance of the bean
when I
try to access a bean from the servlert and then a jsp page.
I do the following:
- create a bean in a servlet,
- get the session from the request object
- put the bean in the session using: session.setAttribute("beanName",
bean)
- forward to a jsp page using: RequestDispatcher.forward()
- in the jsp page, access the bean
<%@ page session="true"%>
<jsp:useBean id="beanName" scope=session class=... />
In the jsp page, it does not find the bean so it creates a new one.
I can see from my debugging that the session object, before and after the
'forward',
is the same. However, it does not have the save attributes. I added debug
print lines
that show the identity of the bean before and after I do the forward() and
that appears
to be the point at which the bean I created is not found and the jsp page
creates a new one.
When control returns from the call to RequestDispatcher.forward(), I was
able to
access the correct instance of the bean.
Why did the jsp page not find the bean the servlet put in the session?
I could really use some help on this and would appreciate any suggestions.
Thanks,
Gary
BTW, I am using Orion 8.2, on NT with JDK 1.2.2
