How to set a global proxy in Java when you can not control how your third party code communicates. Put this static block somewhere in a class that is loaded by your application.
static {
ProxySelector.setDefault(new ProxySelector() {
private final ProxySelector def = ProxySelector.getDefault();
public List<Proxy> select(final URI uri) {
if ("http".equalsIgnoreCase(uri.getScheme()) || "socket".equalsIgnoreCase(uri.getScheme())) {
if (uri.getHost().contains("<changeme>")) {
// Using proxy for <changeme> call
return Arrays.asList(new Proxy(Proxy.Type.SOCKS, new InetSocketAddress("", 8889)));
public void connectFailed(final URI uri, final SocketAddress sa, final IOException ioe) {
throw new UnsupportedOperationException("Not supported yet.");
