my code

        @post         @path("/save/{name}/{data}")         @consumes("application/x-www-form-urlencoded")         public string savedatamap(@queryparam("number") string number,         @pathparam("data") string data,         @pathparam("name") string appname         multivaluedmap<string, string> formparam) throws exception{         boolean response =false'         try{         // business logic         response =true         }          return response;         } 

after googling error found due not specifying content type of data sending - jersey not able locate right messagebodywritter serialize

after added produces anotation method mediatype.text_plain doesn't work ,but when changed return type of method string started working.

i wants know whats problem boolean ,why not working boolean ? , how solve problem without changing boolean string ?

any appreciated.

i code these methods this:

    @post     @path("/save/{name}/{data}")     @consumes("application/x-www-form-urlencoded")     @produces(mediatype.text_plain)     public response savedatamap(@queryparam("number") string number,     @pathparam("data") string data,     @pathparam("name") string appname     multivaluedmap<string, string> formparam) throws exception{     boolean response =false     try{     // business logic     response =true     }      return response.ok().entity(string.valueof(response)).build();     } 

the changes returns jersey http response building string boolean.

i hope helps.
