Trying to pass the list of selected subjects to Controller, but the bean is not receiving the list of subjects.

Here's the code that I'm trying:

$("#submitCreateStudent").click(function() {
      var selSubjectIds = new Array();
      $('#subjectsTableInCreateStudent').find('.jtable-data-row').each(function() {
        if (selSubjectIds.length < 1) {
          selSubjectIds.push($(this).attr('data-record-key') + '$');
        } else {
          selSubjectIds += $(this).attr('data-record-key') + '$';
        }
      });

      if (validateCreateStudentForm()) {

        var data = new FormData();
        data.append('firstName', $("#firstNameInCreateStudent").val());
        data.append('lastName', $("#lastNameInCreateStudent").val());
        data.append('address', $("#studentAddressInCreateStudent").val());
        data.append('collegeName', $("#studentCollegeNameInCreateStudent").val());
        data.append('phoneNumber', $("#phoneNumberInCreateStudent").val());
        data.append('email', $("#emailInCreateStudent").val());
        data.append('studentDepartment', $("#departmentInCreateStudent").val());
        data.append('studentBranch', $("#branchInCreateStudent").val());
        data.append('DateOfBirth', $("#dobInCreateStudent").val());
        data.append('DateOfReport', $("#dorInCreateStudent").val());
        data.append('loginUserName', $("#studentUserNameInCreateStudent").val());
        data.append('loginPassword', $("#passwordInCreateStudent").val());
        data.append('studentSubjects', selSubjectIds);

        //                        data.append('skipInitialTraining', skipInitialTraining);

        $("#maskingId").mask("Saving...");

        $.ajax({
          url: "AddStudent.do",
          data: data,
          //                           
          //Remaining code goes here.
        });
      });

All the details are coming to controller class except for the list of subjects which are selected check boxes.

By default, jQuery supports json format submissions

data :{‘selSubjectIds’:selSubjectIds} or $(this).serialize();

Thanks to Everyone for your efforts.I found my self a way to solve this as Follows

var arr = "";
$('#subjectsTableInCreateStudent').find('.jtable-data-row').each(function() {
                        var record = $(this).data('record');
                        arr += record.subjectId + seperatorForGridCells;   

                    });

Here the arr variable stores every ID as a String by concating with Some seperator "seperatorForGridCells". Then i used StringTokenizer to seperate each id and parsed each id from string type to int.
