How to use SOCKS in Java?

Question

I use 100% working socks and I can't connect through my application.

        SocketAddress proxyAddr = new InetSocketAddress("1.1.1.1", 12345);
        Proxy pr = new Proxy(Proxy.Type.SOCKS, proxyAddr);

    try
    {
        HttpURLConnection con = (HttpURLConnection) new URL(url).openConnection(pr);
        con.setConnectTimeout(proxyTimeout * 1000);
        con.setReadTimeout(proxyTimeout * 1000);
        con.connect();

        System.out.println(con.usingProxy());
    }
    catch(IOException ex)
    {
        Logger.getLogger(Enter.class.getName()).log(Level.SEVERE, null, ex);
    }

So what am I doing wrong? If I'll use HTTP with some HTTP proxy all is working but not with SOCKS.

It's really easy. You just need to set the relevant System Properties and just get on with your regular HttpConnection.

System.getProperties().put( "proxySet", "true" );
System.getProperties().put( "socksProxyHost", "127.0.0.1" );
System.getProperties().put( "socksProxyPort", "1234" );
