servlet-3.0

I have gone through the Spring documentation to know about @RequestBody , and they have given the following explanation: The @RequestBody method parameter annotation indicates that a method parameter should be bound to the value of the HTTP request body. For example: @RequestMapping(value = "/something", method = RequestMethod.PUT) public void handle(@RequestBody String body, Writer writer) throws IOException { writer.write(body); } You convert the request body to the method argument by using an HttpMessageConverter . HttpMessageConverter is responsible for converting from the HTTP request

Is it possible to set up a JAX-RS application using annotations only? (using Servlet 3.0 and JAX-RS Jersey 1.1.0) I tried and had no luck. Using some web.xml seems required. Configuration A (working, but has web.xml configuration) web.xml ... <servlet> <servlet-name>org.foo.rest.MyApplication</servlet-name> </servlet> <servlet-mapping> <servlet-name>org.foo.rest.MyApplication</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> ... Java @ApplicationPath("/") public class MyApplication extends Application { ... } Configuration B (not working, exception thrown) @ApplicationPath("/")
