I set up a cluster with two jboss5.1 server. I use seam Identity for login. In cluster environment,I can not login, the page still on the login page. But in the individual server, I can login, and go to mainpage.
I think it is session issue. Check the log, it says
2009-12-09 16:50:11,306 WARN [org.jboss.seam.web.ExceptionFilter] (ajp-10.200.0.240-8009-3) exception root cause javax.faces.application.ViewExpiredException: viewId:/login.seam - View /login.seam could not be restored.
