how to pass an id to servlet withour using get?

how to pass an id without using get method? only the post method..

here is my code having a get method:

<c:forEach var="student" items="${studentList}">
    <tr>
    <td><c:out value="${student.firstName}" /></td>
    <td><c:out value="${student.middleName}" /></td>
    <td><c:out value="${student.lastName}" /></td>
    <td><c:out value="${student.yearLevel}" /></td>
    <td><c:out value="${student.scholarship}" /></td>
    <td><a href="student?page=edit&id=${student.id}">Edit</a></td>
    <td><a href="student?page=delete&id=${student.id}">Delete</a></td>
    </tr>
</c:forEach>

i tried to use 

   <input type="hidden" name="edit" value="${student.id}">
   <input type="hidden" name="delete" value="${student.id}">

but the first student in list will always be edited and the first in the list of students will be deleted

If you are able to use jQuery, you could do something like that:

<script type="text/javascript">
$(function() {
    $(".studentAction").off("click").on("click", function() {
        var url = "student";
        url += "?page=" + $(this).attr("name");
        url += "&id=" + $(this).val();
        $.ajax({
            type: "POST",
            url: url,
            async: false,
            success: function(data) {
                // on success
            },
            error: function(data) {
                // on error
            }
        };
    });
});
</script>

<input class="studentAction" type="hidden" name="edit" value="${student.id}">
<input class="studentAction" type="hidden" name="delete" value="${student.id}">

You need to create a separate <form> tag for each button.

Otherwise, all of your buttons will share all of the inputs in the form.
