Java APIs

Dears,

Regarding HTTP communications, I would like to auto-detect proxy settings based on system settings.
I can get information on manually configured proxy, using the following code:

import java.net.Proxy;
import java.net.ProxySelector;
import java.net.URI;
import java.net.URISyntaxException;
import java.util.List;

public class Test {

	public static void main(String[] args) {
		System.setProperty("java.net.useSystemProxies", "true");
		try {
			List<Proxy> list = ProxySelector.getDefault().select(new URI("http://www.google.be/"));
			for(int i=0; i<list.size(); i++){
				System.out.println(list.get(i));
			}
		} catch (URISyntaxException e) {
			e.printStackTrace();
		}
	}
}

But ...

I haven't found a way yet to get proxy information from automatic proxy configuration script (pac files).

Has anyone encountered/solved this problem yet?

Many thanks for your help,

Eric
