retrieve data from dataTables in jsp to servlet

guillaume.lheureux.son@gmail.com

I have an editable DataTables (jQuery) that shows the data from my DB in my jsp. I try with no success to retrieve in a servlet the list of objects updated (after modification of the data by a user in the client side) wich are in this DataTables... A "save" button is here to trigg the process.

Here is part of my jsp :

---

<button onclick="saveData()">SAVE</button>

    <script>
        function saveData() {
            var table = $('#myTable').DataTable();
            var data = table.rows().data();
            console.log(data);
            document.location.href="AddLicenceServlet"; 
        }

    </script>


    <div class="x_content">
         <table id="myTable" class="table table-striped table-bordered"    width="100%"></table>
    </div>

    <script type="text/javascript">
    $(document).ready(function () {
        $.ajax({
            type: 'GET',
            url: 'http://localhost:8080//RedlogServer3/licences',
            dataType: 'json',
            headers: {
                Accept: "application/json; charset=utf-8",
                "Content-Type": "application/json; charset=utf-8"
            },
            success: function (response) {
                var dataTablesObj = response;
                generateDataTable(dataTablesObj);
                dataSet = dataTablesObj.data;
            },
            error: function (resultat, statut, erreur) {
            },
            complete: function (resultat, statut) {
            }
        })
    });
    </script>

The console.log(data) shows well the updated data that I want to retrieve in my servlet, so the function "saveData works for that part of the job... The call of the servlet is working to but I don't retrieve any data... The "request.getParameter" are "null"...

Here is my servlet :

---

 @Override
 protected void doPost(HttpServletRequest request, HttpServletResponse  response)
    throws ServletException, IOException {
processRequest(request, response);

        DataService ds = new DataService();

try {
    ds.getLicences();
} catch (ObjectNotFoundException ex) {
    Logger.getLogger(AddLicenceServlet.class.getName()).log(Level.SEVERE, null, ex);
}

    Licence c = new Licence();
    LicenceDAO licenceDAO = new LicenceDAO();

    c.setSerialNumber(request.getParameter("serialNumber"));
    c.setSoftware(request.getParameter("software"));
    c.setCustomer(request.getParameter("customer"));
    c.setName(request.getParameter("name"));
    c.setValidityDate(java.sql.Date.valueOf(request.getParameter("validityDate")));

    licenceDAO.persist(c);

}

How can I retrieve my data from the table in the client side to my servlet in the server side ? Did I miss something to make the communication between jps and servlet possible ?

I'm new in servlet/jsp, any help would be great! Thanks a lot!
