firewall and javaw.exe and jvm

When I write a java program that accesses the internet, my firewall will ask me if it is OK for javaw.exe to access the internet. once java has that permission, any java program seems to have the ability to access the internet. Is there a way to tell the firewall which specific java programs can access the internet, or do they all look the same to the firewall because they are running in a virtual machine?

They should all look the same to FW since they are the same. You exec. java code inside JVM and javaw.exe is the process name for OS.

Try to restrict by IP/URL. Or get a wrapper that will wrap java codein *.exe programm. There are a lot of those on sourceforge now.
