Yes from 5 to 6, IBM made the server a seperate installation that runs as full blown seperate instance of WAS rather than being a part of the IDE. In my case the installer for it was on the same DVD as for RAD.
So how to integrate was6.0 with RAD6.0 I have downloaded portal6.0 with WAS6.0. But when I see in RAD runtime environment I am not able to see WAS and WPS both.
Moreover there is no manual to integrate WAS with RAD [ August 15, 2006: Message edited by: Jignesh Patel ]
At the RAD 6 trial version launchpad, I used 'Install Websphere Portal V5.0 test environment' and it seems to have been installed. I havent tried running a portlet though.
I separately installed WAS 6.1 trial version. I am now able to run my servlet.
