I am testing the cluster in Glassfish 3.1.1
I was following this instrument http://tiainen.sertik.net/2011/03/load-balancing-with-glassfish-31-and.html
I created 1 node in server 1 and the other node in server 2. And I also tried to create cluster in the GUI. However, it also failed!!!
I attached my testing war file(include source code) in the attachment
