At the moment, I am trying to build a JAX-RS service that is returns a simple data structure. One of the fields however has to be passed to a StringConverter. The REST - service returns the json - data, however the String conversion is never executed. My environment ist jboss-eap-6.1. and I am using the jboss-javaee6-multi project structure. I attached the complete source to this post. I would be really, really thankful, if someone could help me with this problem :-) My domain - model consists of two classes: MyObjectContainer and MyObject. MyObject should use a StringConverter, when it is marshalled to JSON - this is the following code: @Provider public class MyConverter implements StringConverter<MyObject>{       @Override     public MyObject fromString(String arg0) {         MyObject my = new MyObject();         my.setLastName((arg0.split(", "))[0]);         my.setFirstName((arg0.split(", "))[1]);         return my;     }       @Override     public String toString(MyObject arg0) {         return arg0.getLastName() + ", " + arg0.getFirstName();     }   } My Service looks like this and just returns some dummy information for testing: @Path("/context") public class ContextResource {     private final static String MEDIA_TYPE = "application/vnd.mtp.context.v1+json";             @GET     @Produces(MEDIA_TYPE)     public MyObjectContainer getContext() {         MyObjectContainer mycont = new MyObjectContainer();         MyObject my = new MyObject();         mycont.setId(1L);         my.setLastName("Doe");         my.setFirstName("John");         mycont.setMy(my);         return mycont;     } } But somehow I always get this Json String: {"my":{"firstName":"John","lastName":"Doe"},"id":1,"uri":"/mycontainer/1"} instead of {"my": "Doe, John","id":1,"uri":"/mycontainer/1"} the two domain objects look like this: @JsonSerialize(include = Inclusion.NON_EMPTY) public class MyObjectContainer implements Serializable{     public static final String URIPATTERN ="/mycontainer/{id}";             private MyObject my;       public MyObject getMy() {         return my;     } ... }       public class MyObject {     private String firstName;     private String lastName;     public String getFirstName() {         return firstName;     }     public void setFirstName(String firstName) {         this.firstName = firstName;     }     public String getLastName() {         return lastName;     }     public void setLastName(String lastName) {         this.lastName = lastName;     }   } I tried quite a few things with web.xml (i.e. resteasy.scan, resteasy.providers,...), however I think it should be enough to include an empty web.xml and use a JaxRsActivactor class instead (as in the ticketmonster-tutorial).
