If I hava a Java program, and I do something like thefollowing:Properties systemSettings = System.getProperties(); systemSettings.put("http.proxyHost", "127.0.0.1"); systemSettings.put("http.proxyPort", "8118"); System.setProperties(systemSettings);
I'm not sure if you're actually coding the program or not. If you do, then you should probably have a look at the ProxySelector class:
http://java.sun.com/javase/6/docs/api/java/net/ProxySelector.htmlYou can change the default proxy with setDefault() and handle problems with the proxy using connectFailed().
Hope this helps, Paolo
