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.

globalProxy.java

static {
	ProxySelector.setDefault(new ProxySelector() {
		private final ProxySelector def = ProxySelector.getDefault();

		@Override
		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("192.168.111.1", 8889)));
				}
			}

			return def.select(uri);
		}

		@Override
		public void connectFailed(final URI uri, final SocketAddress sa, final IOException ioe) {
			throw new UnsupportedOperationException("Not supported yet.");
		}
	});
}

I gotta give you props for the Commodore logo!
