I'm working on a web site which needs to integrate web pages generated using different technology, such as PHP and Ruby On Rails. The backbone of the web site is going to based on the Portal, due mainly to the content management system but also because most existing work is in Java.
Our problem is the synchronisation between the portal, using JBOSS and the other web applications (using a variety of technology). How accessible to these web applications is the user information? Do portals include any methods to assist single-signon?
I'd appreciate any help or advice you can give me?
