I m trying to write spring mvc application with ajax and jquery and stuck at some point and not able to find solution since last 1 week..please help me out.

i want send request for showing all my users in database using ajax,see how i done

Show User List

now javascript ajax request

function doAjaxPost(id)
{ var submitId=id;
  if(submitId=="showUserList")
  {
        $.ajax({
                type: "POST",

                url: "showUserList.html",
                success: function(response){
                // we have the response

                    if(response!='')
                    {
                        //alert(response);
      //Not getting this                $('#listofUser').html(response);
                         $("#homeDiv").hide();
                     $("#userListDiv").show("5");
                    }

        </tr>
    </thead>
     <form action="adminOperations.html" name="userListForm" onsubmit="return ConfirmOperation();"  method="post">   
    <tbody>

        <c:forEach items="${users}" var="users" varStatus="status">
        <tr>
            <td><input type="checkbox" value="${users.id}" id="select" name="select"/></td>
            <td><c:out value="${users.id}" /></td>
            <td><c:out value="${users.firstName}" />&nbsp;<c:out value="${users.lastName}" /></td>

            <td><c:out value="${users.gender}" /></td>
            <td><c:out value="${users.userName}" /></td>
            <%-- <td><c:out value="${users.userPassword}" /></td> --%>
            <td><c:out value="${users.userType}" /></td>
            <td><c:out value="${users.status}" /></td>
            <td><c:out value="${users.emailId}" /></td>

        </tr>

    </c:forEach>
    </tbody>
    <tfoot>
        <tr>

            <td colspan="12" class="rounded-foot-center" align="center">

            <input type="submit" name="activate" id="activate" value="Activate" onClick="ButtonClicked(this);">&nbsp;&nbsp;
            <input type="submit" name="deactivate" id="deactivate" value="Deactivate" onClick="ButtonClicked(this);">&nbsp;&nbsp;

            </td>
        </tr>
    </tfoot>

@ResponseBody doesn't work like that, you should return a JSON and in order to display the content you can do it with jQuery but is a bit tricky, that's why I recommend to you AngularJS, forget JSTL.

Here there is a tutorial where SpringMVC, JSTL and asynchronous requests work together

i am using spring mvc 

 public ModelAndView showUserList(HttpServletRequest request, HttpServletResponse response) throws Exception {
     return new ModelAndView("GiveAnyName","users", userList);
    }

Now you can get User List in JSP Page  

    List rows = (List) request.getAttribute("users");
