Hi,
by the way, you can also define a unique Resource for the main reason
that there is no need to make a distinction based on the format. Both
HTML and XML representations vehicle the same data and represent the
same concept, ie resource.
That is to say :
* Have a single resource
router.attach("/{device}/filelist", FilelistResource.class);
* This resource defines the supported formats, for example in the
constructor:
getVariants().add(new Variant(MediaType.TEXT_XML);
getVariants().add(new Variant(MediaType.TEXT_HTML);
* Then, just implements the method FilelistResource#represent(Variant
variant) where variant is one of the defined variant, and is computed
according to client's preferences.
You can have a look at the tutorial =>
http://www.restlet.org/documentation/1.1/firstResource
And at the tunnel service for several ways to update client's
preferences =>
