where i can learn clustering issue of Sun application server ?

GlassFish is for "a for developer" applicaion server

for now it has not Clustering feature. you should use sun enterprise application server to achieve Clustering.

but you can use some tricks to bring clustering feature to your glassfish , check mod_proxy , mod_jk in apache HTTPD and you will find that you can use HTTPD in front of your glassfish as a load balancer.....
