Is there any way to send parameter to servlet and receive a json in the same AJAX function? Example of what I need:

 function UpdateGrafico(){

          $(function () {

                //---------------------
       //aqui preciso enviar uma data para o servlet realizar um select        
      $.ajax({  
     data: "",  
     dataType: 'json',  
     url: './GetValores', 
     type: 'POST', 
     success: function(data){  

           //recebe os dados json e atualiza pagina 
        });
    }

I need this form because the JSP page has a button and when I click it, it will get a date that the user selected, and used this date for a select in the servlet, which will return the data to update a chart on the JSP page.
