Hi,
PLEASE, ignore my previous mail.
-------------
I agree, if the bean is declared with USEBEAN tag in each (applicable) page with
"session" scope then the same bean exists for that session.
But, i don't see that the latest value is getting passed from one page to another
where the bean is declared using USEBEAN tag with "session" scope.
Example
=======
Assume i have 2 jsp pages (say JSP1.jsp and JSP2.jsp)
In JSP1.jsp
----------------
<USEBEAN NAME="beanId" TYPE="JSP_JAVABEAN.BeanTest" LIFESPAN="session" >
<SETONCREATE BEANPROPERTY="userid" VALUE="INIT-NAME">
<SETFROMREQUEST BEANPROPERTY="*">
</USEBEAN>
<% HttpSession hs = request.getSession(true); %>
<h1> USER_ID-1 is : <DISPLAY PROPERTY="beanId:userid"></h1>
<% beanId.setnew(); %>
<h1> USER_ID-2 is : <DISPLAY PROPERTY="beanId:userid"></h1>
<a href=http://3.209.128.129:80/NASApp/JSP_JAVABEAN/JSP2.jsp> CLICK </a>
Where beanId.setnew() sets the "userid" from INT-NAME to NEWNAME
In JSP2.jsp
----------------
<USEBEAN NAME="beanId" TYPE="JSP_JAVABEAN.BeanTest" LIFESPAN="session" >
<SETONCREATE BEANPROPERTY="userid" VALUE="INIT-NEW-NAME">
<SETFROMREQUEST BEANPROPERTY="*">
</USEBEAN>
<h1> USER_ID-1 is : <DISPLAY PROPERTY="beanId:userid"></h1>
Hear the same bean is declared with Session scope.
Actually, the does not get initialized.
But, still i have "userid" as INIT-NAME and not NEWNAME.
It will be great if you can point me where i am doing mistake.
Thanks... R. Bala

Vinay,
Did you specify a scope??
<jsp:useBean id="my_class" class="my.class" scope="????" />
If you set the scope to 'session', then when a user goes from page to page
he will recieve the SAME BEAN. A new bean will NOT be instantiated.
If ALL users wish to view/modify the bean then you probably want
scope='application'.
I don't know what the default is but it seems like scope='session' is what
you want.
