RE: Cocoon integration with WebPagePortlet
hi there !
regarding the cocoon - jetspeed integration.....how are you maintaining
sessions ?
i mean when i try...i access the cocoon page as a webpageportlet allright
but the session details...like username etc. are not passed to cocoon....i
think this is because the session being maintained within the context
boundary( i have cocoon and jetcpeed running as two different contexts or
webapplications within the same tomcat ! )...
any idea how to do this ?

Re: Cocoon integration with WebPagePortlet
Posted by Paul Spencer <pa...@mikon.com>.
The WebPagePortlet does not maintain a session with the web server, in
your case the servlet Cocoon. Nor does it maintain any cookies.
As far a passing a user name, you can add a username parameter to the
URL of the WebPagePortlet, but the parameter would NOT be populated with
Jetspeed username. See Jetspeed's portlet catalog for documentation on
passing parameters.

RE: Cocoon integration with WebPagePortlet
Posted by Ming Fai <mi...@hongkong.com>.
I think Jetspeed is not so intelligent to maintain a different session
(between Jetspeed to Cocoon) for each user session (between user's browser
and Jetspeed/Tomcat). In order to preserve session in Cocoon, you may pass
the session ID (in Jetspeed) to Cocoon as a parameter and have Cocoon read
the session parameter. (i.e. using <map:act type="request">...)
Unless Cocoon is integrated to Jetspeed (by using CocoonPortlet), I think
there are no better ways.

mingfai
