How to get the system HTTP proxy configuration in Java

Question

Is it possible to get the system proxy configuration in Java?

In the Java Control Panel, you can set a proxy configuration. How can I access to that proxy configuration in order to open URL connections behind a proxy?

Answer 1

Java webstart is getting it from somewhere, isn't it? via the browser somehow?

So it has to be somewhere... but i haven't found it either.

Answer 2

The Java Plugin gets it from the system settings. If the app has to be started as either applet or webstart you can use the webstart/applet APIs for this. Otherwise you have to use native code. Look at the various JniWrapper's WinPack and the JDIC libs - they might have done the heavy lifting for you.

Answer 3

oh, just look at that question. there was a sample with a solution.

currently all samples I've seen use SUN's undocumented APIs (com.sum packages), which result in warnings at compile time...
