Like for scripts and servlets it should be possible to bind jax-rs classes to both path and type.
The Jax-Rs standard defines a powerful and convenient way to write classes providing rest resources. Compared to servlets, this standard can offer a simpler and more elegant way to write such application. The choice is not an exclusive one, it is perfectly possible to mix both development styles. The only little compatibility issue is that jax-rs support regex-path matching while sling doesn't, that's why I had to resort to the OptingServlet. > > Also, considering SLING-2191 and the related thread from a few minutes > ago, it might be better to mount the JaxRsServlet on a path (/jaxrs by > default maybe?) rather than by resource type, to avoid two resolution > mechanisms fighting for the same URL space. Implementation details shouldn't affect the URI, it should be possible to port the same service from script to servet or jax-rs (with the extension to bind to sling:types).
