HttpSession size

Hi

   We are using Beehive page flows in our application.  The
DynaActionForms are being put into HttpSession to maintain
state. The
DynaActionForms have reference to the PageFlowActionServlet
which in
turn has references to Handlers and other heavy objects.
Because of this
the HttpSession size is 20-25MB more. Is there a way to keep
the
HttpSession size low?

 

Thank you

Bharat

Hi Bharat,

How are you using DynaActionForms in your page flows? Are
you defining
them with a struts config file that you merge into your page
flow? And
is the form-bean
type="org.apache.beehive.netui.pageflow.DynaFormData&qu
ot;
in the config file? And do you explicitly set the
<action> element
scope to session for the merged config?

There is an example of using dynamic form beans in a page
flow in the
netui-samples of the Beehive distribution. See the
Controller and
struts config file in...
<BEEHIVE_HOME>/samples/netui-samples/src/advanced/dyna
forms/

Note that in the NetUI framework, one page flow controller
gets saved
to the session as the current page flow. When a user
navigates to
another page flow, the first is destroyed and the new page
flow
replaces it in the session. And if any action forms are
session scoped
they will be on the user session. However, I'm not sure how
your
"DynaActionForms have reference to the
PageFlowActionServlet".

Kind regards,
Carlin

Hi Bharat,

I was just looking at this some more and think I understand
what
you're looking at. The Struts ActionForm base class has the
reference
to the ActionServlet (in this case the
PageFlowActionServlet). But
this reference does not increase the size of a user session
dramatically. Each ActionForm would just have a reference to
the same
ActionServlet object in memory. There's just one
PageFlowActionServlet
instance in memory for the web app, not one per ActionForm
or session.

Maybe check for the objects that are stored in your page
flow to see
if they contribute to the size of the session as well as the
number of
session scoped beans and what they contain.
