java - Setting up Jax-rs 2.2 with Jetty -

i'm trying set rest services on jetty using jersey jaxrs. can't json data through rest service class though. ajax requests keep getting "unsupported media type" error , status. regardless of @produces , @consumes annotations add methods though should both mediatype.application_json.

i can't find decent documentation on jersey , loads of questions, blogs, , other resources seem out of date. looks jersey has undergone lot of changes , i'm @ loss should looking. set following based on jersey webapp archetype:

web.xml:

<servlet>     <servlet-name>jersey web application</servlet-name>     <servlet-class>org.glassfish.jersey.servlet.servletcontainer</servlet-class>     <init-param>         <param-name>jersey.config.server.provider.packages</param-name>         <param-value>com.my.package.rest</param-value>     </init-param>     <load-on-startup>1</load-on-startup> </servlet>  <servlet-mapping>     <servlet-name>jersey web application</servlet-name>     <url-pattern>/rest/*</url-pattern> </servlet-mapping> 

code snippet:

@path("/users") public class userservice {      // plain text works!     @get     @consumes(mediatype.text_plain)     public string list(){         return "got it!";     }      // json doesn't work! >:(     @post     @consumes(mediatype.application_json)     @produces(mediatype.application_json)     public user create(user user) {         mocks.users.add(user);         return user;     } 

my parent pom manages these dependencies ahd second of these 2 dependency in jax-rs project pom.

<dependency>     <groupid>org.glassfish.jersey</groupid>     <artifactid>jersey-bom</artifactid>     <version>2.2</version>     <type>pom</type> </dependency> <dependency>     <groupid>org.glassfish.jersey.containers</groupid>     <artifactid>jersey-container-servlet-core</artifactid>     <version>2.2</version> </dependency> 

do need add support json?

have read chapter dedicated json in users guide? easiest way adding dependency on moxy , json support work out-of-the-box (you don't need explicitly register features modules provides make work opposed other json modules in jersey):

<dependency>     <groupid>org.glassfish.jersey.media</groupid>     <artifactid>jersey-media-moxy</artifactid>     <version>2.2</version> </dependency> 

anyways jersey provides more modules handling json media type:

• moxy (examples: json-moxy, bean-validation-webapp)
• jackson (example: json-jackson)
• java api json processing (json-p) (example: json-processing-webapp)
• jettison (example: json-jettison)
