Settare Proxy in Eclipse

[matthew80]

Probabilmente non è un problema di proxy...
Questo è il programma:

import java.io.*;
import java.net.*;

public class URLConnectionSample {

    public static void main(String[] args) {
        StringBuffer document = new StringBuffer();
        String line = null;

        try {
            // Il client si connette al server
            URL url = new URL("http://www.html.it");
            URLConnection conn = url.openConnection();

            // Il client legge lo stream di input del server
            BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            while ((line = reader.readLine()) != null) {
                document.append(line);
            }
            reader.close();

            // Ciò che il client ha letto viene memorizzato in un file
            FileWriter out = new FileWriter("document.html");
            out.write(document.toString());
            out.close();

        } catch (Exception e) {
            e.printStackTrace();
        } 
    }
} 

E questo è l'errore:

Qualche anima pia che mi aiuta?
