问题
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 application? I.e. something similar to sticky sessions in .NET.
回答1:
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.
回答2:
Take a look at Single Sign On functionality.

回答3:
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
