You instantiated the RewriteHandler but didn't actually use it or hook it
up into your handler list.
Add it to your handlers list.
handlers = new HandlerList(new Handler[]{rewrite, ctx, new
DefaultHandler()});
Also, don't combine ResourceHandler and ServletContextHandler.
Set a proper/valid Base Resource for your ServletContextHandler.
Add the DefaultServlet to the ServletContextHandler.
Finally, configure your REST Implementation to NOT serve static resources,
ever.
