[undertow-dev] serving static files

You need to make a choice in the handler when to delegate to the next handler (i.e. servlet), and when to intercept the request and serve your static files.
Generally you will do this by simply looking at the path. If for example you only want to serve some paths from JAX-RS you can use a path prefix predicate to specify the paths that get delegated to the servlet handler, and hand everything else to your resource handler.
Note that this is all a bit of a hack, the correct way to do this would be to modify the resteasy server so it does not register itself as the root handler.
