java - using map in pojo object not mapping the request -

i creating restful apis. doing @post call , request body below:

{     "user": "test1",     "animals": {         "cat": "3",         "dog": "5",         "cow": "10"     } } 

service :

@path("/saveownerdata")     @post     @produces({ "text/html", "application/json", "application/text" })     public response saveownerdata(ownerdata ownerdata) {     //save db } 

entity object:

@xmlrootelement @entity(value = "ownerdata", noclassnamestored = true) public class ownerdata {  @id private string _id; private string user; private map<string, string> animals;  public string get_id() {     return _id; }  public void set_id(string _id) {     this._id = _id; }  public string getuser() {     return user; }  public void setuser(string user) {     this.user = user; }  public map<string, string> getanimals() {     return animals; }  public void setanimals(map<string, string> animals) {     this.animals = animals; } 

}

questions:

• the request mapping "user" data not "animals" data
• i tried org.codehaus.jettison.json.jsonobject well, same issue
• if can't map or json object, how can map kind of request directly pojo

thanks in advance.
