here's controller java 

//upload files      @requestmapping(value="/upload", method=requestmethod.post)     public @responsebody string handlefileupload(@requestparam("name") string name,@requestparam("file") multipartfile file){         if (!file.isempty()) {             try {                 byte[] bytes = file.getbytes();                 bufferedoutputstream stream =                         new bufferedoutputstream(new fileoutputstream(new file(name)));                 stream.write(bytes);                 stream.close();                 return "you uploaded " + name + "!";             } catch (exception e) {                 return "you failed upload " + name + " => " + e.getmessage();             }         } else {             return "you failed upload " + name + " because file empty.";         }     }

and here's js controller

//upload files         $scope.upload=function(rap){               $http.post("http://localhost:8080/upload?$name="+rap.name+"$file="+rap.file)                    .success(function(){                  console.log('post succeded !');              })              .error(function(){                  console.log('post failed .');              });         }

when run application in chrome use development tools , when click on importreports have typeerror: cannot read property 'name' of undefined. ideas?
