New to Oracle - Ques. about globals.jsa

Question

Hi,
I'm trying to put together a simple web application (JSPs only) to run under Oracle 9i. For this application, I need to maintain a persistent variable among all users and sessions (we would set the variable initially, once, via our app, and the variable would be available to all of our JSPs).
I guess with other containers, I would use ServletContext, but I understand this is not supported in Oracle, and I may need to use globals.jsa instead.
This is a simple requirement I think, and I think I actually have it working, but just want to check if I'm doing things correctly.
What I have so far is a globals.jsa in my apps home directory:
<%-----------------------------------------------------------

<event:application_OnStart>
     <jsp:useBean id="myvar" class="oracle.jsp.jml.JmlString" scope = "application" />
</event:application_OnStart>
<event:application_OnEnd>
     <jsp:useBean id="myvar" class="oracle.jsp.jml.JmlString" scope = "application" />
</event:application_OnEnd>
<event:session_OnStart>
     <%-- Acquire beans --%>
</event:session_OnStart>
<event:session_OnEnd>
     <%-- Acquire beans --%>
</event:session_OnEnd>
And, in my JSPs, I add:
<jsp:useBean id="myvar" class="oracle.jsp.jml.JmlString" scope = "application" />
Then, I access the 'global' variable:
To retrieve: String s = myvar.getValue();
or
To update: myvar.setValue("whatever");
Like I said, this seems to be working, but I'm just checking. I'm kind of unclear about what I have in the globals.jsa itself. Is what I have above correct?
Thanks,
Jim

Jim, I am not sure if I have ever used globals.jsa or not. However, if you got it working, then it is working. Please take a look at the documentation "chapter 9, Oracle JSP in Apache JServ" in
Oracle9i Support for JavaServer Pages Reference
Release 2 (9.2)
Part Number A96657-01
Current url is http://download-west.oracle.com/docs/cd/B10501_01/java.920/a96657/apjsvsup.htm#1015160
Any particular reason that you are trying to use globals.jsa as of now?! Please note the j2ee aspect in the Oracle java product has been moved forward enormously. For a minor example, globals.jsa is not longer supported in later releases. It was only a mechanism for implementing the JSP specification in a servlet 2.0 environment as Web applications and servlet contexts are not fully defined in the servlet 2.0 specification. Since we have passed year 2002, there is no reason to support globals.jsa.
Please have fun trying oc4j 10.1.2 production or oc4j 10.1.3 developer preview.
