Paul added support for pluggable type system in Jersey. All the supported types need to implement the EntityProvider interface and are registered in the META-INF/services file javax.ws.rs.ext.EntityProvider. Jakub used that system to add support for JSON encoding. Jersey is the GlassFish project that is implementing JAX-RS |
The JSON binding in JAX-RS enables to use application/json as
the MIME type and specify
JSONArray,
JSONObject as
method parameters and return type. The JSON binding in JAX-RS enables to write
code like the following:
@UriTemplate("/rates")
public class ExchangeRates {
@ProduceMime("application/json")
@UriTemplate("CZK")
public JSONObject getRates() {
try {
return new JSONObject()
.put("USD", 20.04);
} catch (JSONException ex) {
throw new WebApplicationException(ex);
}
}
}
JAX-WS takes advantage of a similar pluggable encoding layer in their implementation to provide a JSON binding.
