Post Map<String,Object> to Spring Controller using Ajax -

i'm trying post model contains map controller, have tried 2 ways:

first i'm using regular tag, reaches controller right string key, object of map gets null

<c:foreach items="${productquote.prodcontm}" var="productquoteobjtm" varstatus="status"> <tr>    <td>${productquoteobjtm.key}</td>    <td>    <input value="${productquoteobjtm.value.qty}" name="prodcontm['${productquoteobjtm.key}']${productquoteobjtm.value}" id="inputquote${status.index}"/>     </td>    <td>${productquoteobjtm.value.totalprice}</td>    </tr>   </c:foreach>  

also tried pass map using form tag instead, shown in line below:

doesn't reach controller, i'm passing form ajax function:

 $(document).ready(function() { $('#quoteform').submit(     function(event) { $.ajax({     url : $("#quoteform").attr("action"),     data : $("#quoteform").serialize(),     type : "post",   success : function(response) {     $("#prodconfig").html(response); },     error : function(xhr, status, error) {     alert("error:"+xhr.responsetext); }}); return false;     }); }); 

this controller expecting model:

    @requestmapping(value="/saveconfig",method = requestmethod.post)     public modelandview currentquote(@modelattribute("productquote") productquotedto productquote) {     ..     } 

please let me know i'm doing wrong. thanks!

you should use jsp forms instead of raw html forms, make life whole lot simpler.
suppose productquote.prodcontm map:

<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form" %>  <form:form id="quoteform" commandname="productquote">     <c:foreach items="${productquote.prodcontm}" var="entry">         <tr>             <td>${entry.key}</td>             <td>                 <form:input path="prodcontm['${entry.key}'].qty" />             </td>             <td>${entry.value.totalprice}</td>          </tr>     </c:foreach> </form:form> 

i not if prodcontm['${entry.key}'].qty in path work.
otherwise, may have adapt map value's dto simple string or primitive
