			The callback mechanism within a site works well.
			

			But I want to make sure whether it will work across different sites.
			

			while referring the forum,I found that It doesnt work across firewall and that article too posted at 2004.
			

			Is java 5.0 supports this mechanism ?
			

			I want my RMI server to notify the RMI client whenever it has something to say.
			

			

			

			

			thanx in advance

I believe RMI works across standard TCP ports in both directions (call and callback). That being said, Java is no more special than any other language here... if a firewall says "no incoming connections to port X / no outgoing connections to port Y" then you are out of luck (unless you can get the needed port on the firewall opened for your traffic).
