Share Session between 2 Java EE applications deployed in JBoss AS

I have 2 Java EE applications which need to share some common user related data of a logged in user.

Is there anyway by which I can store this data in the session from one application and retrieve that data in a second appl开发者_如何学Cication? I.e. something similar to sticky sessions in .NET.

Two separate Java EE applications will be having separate session data. If they are on the same domain and you want to share couple of attributes, then you could use a cookie and set attributes into the cookie and read them in each web app.

Take a look at Single Sign On functionality.

Single sign-on is the way to go (as prescribed). OpenId http://en.wikipedia.org/wiki/OpenID (Providers include Google, Yahoo, MSN etc) is worth a look
