    var value = father.value;
    var url  = $("#ajaxUrl").val();

    $.post(url,{'fatherId' : value})
    .success(function(){

@RequestMapping(params="action=getChildClaimsAjax")
    public void getChildClaims(ResourceRequest request,ResourceResponse response) throws NumberFormatException, EcareException_Exception, IOException{
            List<CustomerClaim> childClaims =ServiceFactory.getCustomerService().getClaimByFatherId(Integer.parseInt(request.getParameter("fatherId")));
            Gson gson = new Gson();
            String json = gson.toJson(childClaims);
            PrintWriter out = response.getWriter();
            out.write(json);
            out.flush();
            out.close();
    }

Use <portlet:resourceURL/> as ajaxURL(in your case) in jsp.jspf, in you are referring.

Instead of @RequestMapping annotation use @ResourceMapping, this change would resolve your issue.
