Hello Everybody,
I am still facing the problem with Inter JSP Portlet Communication.I have a JSP which
is displaying the News Titles from mysql database.
When i click(titles are having a link) on a particular title the corresponding
description of news should be displayed(from datbase) in a separete(another) JSP
portlet.
I am not able to get the link from first jsp to second jsp.I am getting 'null' for the
first time and nothing afterwards.Should i define two jsp's as templates in one
portlet-entry in .xreg?.I defined both JSP's differently in .xreg file.Below is my
coding for both jsp's ..please tell me where i am doing mistake?.I spent lot of time
digging around.I am using Jetspeed-1.5.
Thank you very much for your time and patience,
Maruthi.
