Giuseppe,

If the problem is accessing the web via a proxy server, you may need to
set the java proxy properties.
The following code does this, or you can set them on the command line -
the code comments give the details for this:


private static Properties originalProperties = null;

/** Utility method for use when HTTP proxy has not been set on the
command line **/    
public static void setProxy(String proxy, String port)
{
    
// ******** Have to set up system properties for HTTP to    
// work************ e.g on command line, set:
// -Dhttp.proxyHost=hostname -Dhttp.proxyPort=80

if(originalProperties == null)	    
{		
  originalProperties = System.getProperties();
}
Properties MyProps = new Properties(originalProperties);	
MyProps.setProperty("http.proxyHost",proxy);	
MyProps.setProperty("http.proxyPort",port);	
System.setProperties(MyProps); 
}

Hope that helps,
