package com.my.dto;  import java.io.serializable;  import javax.xml.bind.annotation.xmlelement; import javax.xml.bind.annotation.xmlrootelement;  import org.codehaus.jackson.annotate.jsonproperty; import org.codehaus.jackson.map.annotate.jacksoninject;  @xmlrootelement(name="useraddress") public class useraddress implements serializable{      private int streetno;     private string city;     private string state;     private int pincode;     @xmlelement     public int getstreetno() {         return streetno;     }      public void setstreetno(int streetno) {         this.streetno = streetno;     }     @xmlelement     public string getcity() {         return city;     }     public void setcity(string city) {         this.city = city;     }     @xmlelement     public string getstate() {         return state;     }     public void setstate(string state) {         this.state = state;     }     @xmlelement     public int getpincode() {         return pincode;     }     public void setpincode(int pincode) {         this.pincode = pincode;     }  }

this userinformation class: in class have create setter , getter useraddress class.

package com.my.dto;  import java.io.serializable;  import javax.xml.bind.annotation.xmlelement; import javax.xml.bind.annotation.xmlrootelement;  import org.apache.http.entity.serializableentity; import org.codehaus.jackson.annotate.jsonproperty;  @xmlrootelement(name="userinformation") public class userinformation implements serializable {      private string name;     private int age;     private int roll;     private useraddress useradd;      @xmlelement     public useraddress getuseradd() {         return useradd;     }      public void setuseradd(useraddress useradd) {         this.useradd = useradd;     }     @xmlelement     public string getname() {         return name;     }     public void setname(string name) {         this.name = name;     }     @xmlelement     public int getage() {         return age;     }     public void setage(int age) {         this.age = age;     }     @xmlelement     public int getroll() {         return roll;     }     public void setroll(int roll) {         this.roll = roll;     }  }

this resteasy web service both , post method :

package com.my.app;  import javax.jws.soap.soapbinding.use; import javax.ws.rs.consumes; import javax.ws.rs.get; import javax.ws.rs.post; import javax.ws.rs.path; import javax.ws.rs.produces; import javax.ws.rs.core.mediatype; import javax.ws.rs.core.response;  import org.codehaus.jettison.json.jsonobject;  import com.my.dto.useraddress; import com.my.dto.userinformation; import com.my.dto.usersuccess;  @path("/info") public class showuserinfo {     @get     @path("/get")     @produces(mediatype.application_json)     public userinformation getproductinjson() {          userinformation infoobj = new userinformation();         useraddress useraddress=new useraddress();         useraddress.setcity("new delhi");         useraddress.setstate("delhi");         useraddress.setstreetno(447);         useraddress.setpincode(110092);          infoobj.setname("ravi raj");         infoobj.setage(21);         infoobj.setroll(101);         infoobj.setuseradd(useraddress);          return infoobj;  }      @post     @path("/post")     @consumes(mediatype.application_json)     @produces(mediatype.application_json)     public response createproductinjson(userinformation infoobj) {          return response.status(200).entity(infoobj).build();      }  }

following jquery ajax call , post request web service.

this call get:

var uri="http://localhost:8080/webserviceusingrestful/"; var studentdata; function checkwebservice(){      $.ajax({         url : uri+"rest/info/get" ,         type : 'get',         contenttype : 'application/json; charset=utf-8',         // request data type         datatype : 'json',         cache: false,         success : function(data, status, req) {             alert("pass calling api");              var responsejsonobj = json.parse(req.responsetext);              printdata(responsejsonobj);          },         error : function(req, status, error) {            alert("fail calling api");          },         // set user basic authentication data request header         /*beforesend : setheader*/     });  }

this working fine.i have got json array. right.

but when post data service using code shows error.

function insertdata(){     var request = new object();     request.name=$('#usernamefld').val();     request.roll=$('#rollfld').val();     request.age=$('#agefld').val();      request.useradd.streetno=$('#streetfld').val();     request.useradd.city=$('#cityfld').val();     request.useradd.state=$('#statefld').val();     request.useradd.pincode=$('#pinfld').val();      $.ajax({         url : uri+"rest/info/post" ,         type : 'post',         contenttype : 'application/json; charset=utf-8',         data : json.stringify(request),         // request data type         datatype : 'json',         cache: false,         success : function(data, status, req) {             alert("api working fine..!!");              var responsejsonobj = json.parse(req.responsetext);             $('#insertdivid').show();          },         error : function(req, status, error) {            alert("fail calling api");          },         // set user basic authentication data request header         /*beforesend : setheader*/     }); }

this call show error streetno this: uncaught typeerror: cannot set property 'streetno' of undefined if placed code .

function insertdata(){     var request = new object();     request.name=$('#usernamefld').val();     request.roll=$('#rollfld').val();     request.age=$('#agefld').val(); request.useradd{"city":$('#cityfld').val(),"streetno":$('#streetfld').val(),"state":$('#statefld').val(),"pincode":$('#pinfld').val()};      $.ajax({         url : uri+"rest/info/post" ,         type : 'post',         contenttype : 'application/json; charset=utf-8',         data : json.stringify(request),         // request data type         datatype : 'json',         cache: false,         success : function(data, status, req) {             alert("api working fine..!!");              var responsejsonobj = json.parse(req.responsetext);             $('#insertdivid').show();          },         error : function(req, status, error) {            alert("fail calling api");          },         // set user basic authentication data request header      }); }

this working fine not valid way send request object using ajex call.

please go through code , give me idea problem. alot..!! note: if 1 have jax-rs tutorial link ..please add link me. thanks

you need declare request.useradd, before adding it

function insertdata(){   var request = new object();   request.name=$('#usernamefld').val();   request.roll=$('#rollfld').val();   request.age=$('#agefld').val();    request.useradd = {} // <--- declare useradd    request.useradd.streetno=$('#streetfld').val();   request.useradd.city=$('#cityfld').val();   request.useradd.state=$('#statefld').val();   request.useradd.pincode=$('#pinfld').val();

but why is

data : json.stringify(request)

not valid request?

regards

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
