AngularJS: Get $http.post data in JSP

Question

I wrote the below code to send the $http.post request

$http({
    url: '/OA_HTML/ReportColumnSelection.jsp',
    method: 'POST',
    data: JSON.stringify({myData : $scope.reportColumns}),
    headers: {'Content-Type': 'application/json;charset=utf-8'}
  })
  .success(function(response){
    $scope.viewColumns = response.columnData;
  })
  .error(function(response){
    //Error Log
    console.log('Inside saveReportColumns Error');
  });

Now the problem is i'm unable to get the "myData" JSON in ReportColumnSelection.jsp

request.getParameter("myData");

Please let me know if i'm doing anything wrong.

AngularJS Version 1.4.7

Code to save report columns:

$scope.saveReportColumns = function () { 
        console.log('Inside saveReportColumns'); 
        $http({ url: '/OA_HTML/eis/jsp/reporting/reports/newreport/columnselection/EISRSCReportColumn‌SelectionAM.jsp', 
        method: 'POST', 
        data: JSON.stringify({myData:$scope.reportColumns}), 
        headers: {
            'Content-Type': 'application/json;charset=utf-8'
        } 
    }).success(function(response){}).error(function(response){ 
        //Error Log console.log('Inside saveReportColumns Error');
    }); 
};

Can you post some more code from your JSP where you post the request and handles the response? — Daniel B

@dfsq thanks for the suggestion. The issue got resolved when i sent the request as you suggested and in response i used request.getInputStream() — Sukesh Kotian

The $http services default content type is application/json, which your JSP cannot parse.

You can either,

change the content type of the request to application/x-www-form-urlencoded;charset=utf-8 (which might have other implications)

or

read it as a stream like below.

InputStream body = request.getInputStream();

It might be a good idea to leave the content type as it is, and instead read the request body and parse it with a library such as google/json

BufferedReader reader = request.getReader();
Gson gson = new Gson();

the problem got solved with your solution. I'm able to get the JSON. Issue is i have to use Java 1.4, sadly GSON doesn't support this vesrion :(

I removed the content type and used JSON which is compatible with Java 1.4
