Hi!
I saw an applet created to test download speed. But I'm confused how to achieve that. You can go to this url and check it out. It's a government website. I thought java has no support like ping, traceroute.

Java has something called the JNI (Java Native Interface), which allows it to call libraries written in the host's native code. That's probably how they're doing it.

Hmm.... Yeah, I think that is the only way. But using JNI restricts system Independence, right?
Lost!

Yes, but if you absolutely must have native access to the host, you're gonna be sacrificing platform portability anyway, so it should only be used when there is a very good reason to do so.
You can, however, write multiple libraries, one for each platform, and have Java detect the platform and load the appropriate library at runtime.

Are you sure you're wanting to use the java applet route? With so many security issues in java right now, I leave all of my java plugins disabled and I'm sure many others do too.
