ster the annotated resource. ResourceConfig resourceConfig = new ResourceConfig(HelloResource.class); // Add new "hello2" resource using the annotated resource class // and overriding the resource path. Resource.Builder resourceBuilder = Resource.builder(HelloResource.class, new LinkedList<ResourceModelIssue>()) .path("hello2"); // Add a new (virtual) sub-resource method to the "hello2" resource. resourceBuilder.addChildResource("world").addMethod("GET") .produces("text/plain") .handledBy(new Inflector<Request, String>() { @Override public String apply(Request request) { return "Hello World!"; } }); // Register the new programmatic resource in the application's configuration. resourceConfig.registerResources(resourceBuilder.build()); The following table illustrates the supported requests and provided responses for the application configured in the example above.

Request	Response	Method invoked
{@code "GET /hello"}	{@code "Hello!"}	{@code HelloResource.sayHello()}
{@code "GET /hello2"}	{@code "Hello!"}	{@code HelloResource.sayHello()}
{@code "GET /hello2/world"}	{@code "Hello World!"}	{@code Inflector.apply()}
