Question

Is it possible to capture network events using Java?

For example, when I connect my ethenet adapter to a hub there is ‘connectivity’ and this is detected by windows XP and a ‘bubble’ displayed to the user. Does Windows also broadcast an event which can be captured by applications and more specifically applications written in Java?

Answer 1

As far as I know there is not an event for this that Java can detect — it’s very OS specific. What you can do is poll the available network interfaces every so often.

Enumeration<NetworkInterface> e = NetworkInterface.getNetworkInterfaces();
