Hi Pradeep
A servlet has direct access to the http session as normal. The "portlet
session" is the same beast, but the variable names have a prefix indicating
which portlet they belong to. If there are n portlets on a single page,
there will be n portlet sessions.
The portlet JSR 168 API lets you choose where a portlet saves data - either
in the global session (aka the servlet http session) or in the "private
portlet session" for the portlet.
- Anything a servlet stores into the session is available to all portlets.
- Anything a portlet stores in the global session will be available to a
servlet.
- Anything a portlet stores in the portlet session will also be available
to the servlet, but the name will have been mangled to provide a separate
namespace for each portlet instance, making access quite difficult.
- To share session data, the servlet and the portlets must all be part of
the same web application (i.e. packaged in the same .war file).
Also, this only applies to the action phase. To have data available during
the render phase, you need to pass it across at action time. I'm not sure of
the API call (setRenderParameters() ??).
Hope this does not confuse you further, and I hope I got it right :) The JSR
168 specification has a fairly lucid description of how this all works.
Regards
Ron

Subject: RE: Login portlet action mapping.
That's a good solution Woonsan,
But it is compromising the entire notion of the image verification.
In the HTML view source it is showing the random number like below if i use
parameters in the URL.
<img src="/j2-admin/Cap_Img.jsp?random=1e131">i tried to use the httpsession
in login.jsp to store the attribute as well. it doesn't work, i mean the
value will be null if you access the same in Cap_Img.jsp.
So is there any way i can access the portletSession from even within
servelt?
Thanks & Regards,
Pradeep.
