rest - Server internal error with post request in api restful -

i'm having problems post requests in api restful i'm testing , don't see error.

here i've api

import javax.ws.rs.consumes; import javax.ws.rs.get; import javax.ws.rs.post; import javax.ws.rs.path;  import test.api.models.test; import test.api.mediatype;  @path("/test") public class testresource {      @get     public string getsomething(){         return "ok get";     }      @post     @consumes(mediatype.test)     public string postsomething(test test){          system.out.println("got:  " + test);         return "ok post";     }  } 

the problem when request localhost:8080/test-api/test postman application, "ok get". if post request 500 server error. i'm setting correctly content-type header field. error is:

"message": "http 500 internal server error", "status": 500 

and how i'm sending data:

{   "a": "one",   "b": "two" } 

i think problem can in test class, because if change input parameter of postsomething method string type "ok post".

here test class don't see strange...

public class test {      public string a;     public string b;      public test ( string a, string b){         this.a = a;         this.b = b;     }      public string geta() {         return a;     }      public void seta(string a) {         this.a = a;     }      public string getb() {         return b;     }      public void setb(string b) {         this.b = b;     }  } 

anyone see strange?

thank you.

the problem maybe post data, maybe have url encode post data. try following post data, it's url encoded.

%7b%22a%22%3a%20%22one%22%2c%22b%22%3a%20%22two%22%7d 

or can try http://meyerweb.com/eric/tools/dencoder/ encode own data.
