Hi all,
I am getting a wierd behaviour from application beans: they seem to remain
different for pages within my application.
I have a very simple application, in which I need application beans. I have
two pages that go like this:
page1.jsp
<jsp:useBean id="gums" scope="application" class="gov.bnl.gums.GUMS" />
<% gums.doSomething(); %>
----
page2.jsp
<jsp:useBean id="gums" scope="application" class="gov.bnl.gums.GUMS" />
<% gums.doSomethingElse();%>
I would expect the pages to share the object, but they appear to create one
object per page, and then keep it throught the life of the app. I logged the
stack trace, to be sure I wasn't creating them somehow:

They both come from jasper... am I missing something?
Thanks,
