hi,
try with out execute webstart,
import java.net.InetSocketAddress;
import java.net.Proxy;
import java.net.ProxySelector;
import java.net.URI;
import java.net.URL;
import java.util.Iterator;
import java.util.List;
import com.sun.java.browser.net.ProxyInfo;
import com.sun.java.browser.net.ProxyService;
public class MainTest {
* @param args
public static void main(String[] args) {
// TODO Auto-generated method stub
//detect("http://www.myuniportal.com");
detect2();
public static void detect2() {
try {
System.setProperty("java.net.useSystemProxies","true");
List l = ProxySelector.getDefault().select(
new URI("http://www.yahoo.com/"));
for (Iterator iter = l.iterator(); iter.hasNext(); ) {
Proxy proxy = (Proxy) iter.next();
System.out.println("proxy type : " + proxy.type());
InetSocketAddress addr = (InetSocketAddress)
proxy.address();
if(addr == null) {
System.out.println("No Proxy");
} else {
System.out.println("proxy hostname : " +
addr.getHostName());
System.out.println("proxy port : " +
addr.getPort());
} catch (Exception e) {
e.printStackTrace();
public static void detect(String location)
String proxyHost;
int proxyPort;
try {
ProxyInfo info[] = ProxyService.getProxyInfo(new URL(location));
if(info != null && info.length>0)
proxyHost = info[0].getHost();
proxyPort = info[0].getPort();
System.out.println("PROXY = " + proxyHost + ":" + proxyPort);
}catch (Exception ex) {
System.err.println(
"could not retrieve proxy configuration, attempting direct connection." + ex);
