Take a look at the class PortletSessionState. With it you can do something
like
PortletSessionState.setAttribute(portlet, rundata, "name", "value");
and then in another request
Object val = PortletSessionState.getAttribute(portlet, rundata, "name');
There are other helper methods as well. Also, PortletConfigState is another
helpful class when using the GenericMVC portlet.

Subject: Storing Data across multiple requests
Date: Fri, 26 Mar 2004 10:11:45 +0100
Hy,
I am currently developing my first of a bunch of portlets on the jetspeed
1.4 platform
(with the intent to switch to 1.5 as soon as the next beta release will be
available).
I've chosen to implement the MVC pattern and want to use jsp as the view
technology.
In this setting i subclass GenericMVCAction for my action handling and let
my
Logic class store the data for the view in the context that I have
available
in my Action class and transferred from there to the logic class.
Now, it would be desireable, to have the data in that context available
throughout
multiple http requests of my portlet ( it would save me, for example, doing
database
requests again and again when i am only paging through multiple pages of
the same result)
and I assumed, GenericMVCContext would work like that. But I see, it
doesn't, because
everything i store in the context on one request is gone with the next one.
Is there a way to make GenericMVCContext persistent throughout mutliple
requests?
Thanks,
Henning
