the program written is working at home but not in college.

the program takes in a URL of a web-page as input.
the program is expected to retrieve the content of a web-page which is then further analysed to find the emailids present in that web-page.

the web-pages present on the local hard disk are retrieved properly but when the URL is over Internet ex: it is not working.

the college provides us Internet Service through a proxy server.
we are working on JDK6.0 kit and Windows XP SP2 Operating System.we are developing this application under eclipse2.0 IDE tool.
the college system has Pentium processor and 256MB RAM.

can you please help me in solving this problem?

Proxy Server settings :

method 1)
proxy server's address is
it is set using setProperty method.
proxy server's port is 80

method 2)
passing arguement to "java" command

java -Dhttp.proxyHost= -Dhttp.proxyPort=80 URLdemo

when either of the one is used the message i am getting error

the program is as follows

import javax.swing.*;

public class URLdemo {
URL url;
public static void main(String[] args) {
URLdemo ur=new URLdemo();

public void getContent(){

String sa=System.getProperty("http.proxyHost");

url=new URL(JOptionPane.showInputDialog("Enter url"));
BufferedInputStream is=new BufferedInputStream(url.openStream());
String s="";
while( is.available() != 0 ){
catch( MalformedURLException murle){
System.out.println("URL error!");
catch( IOException ioe){
catch( Exception e){

output along with stack trace Unexpected end of file from server

Not advanced Java. I'll move this to "Sockets and Internet Protocols."
