Passing JSP date to Servlet

I have a Datepicker bootstrap as below, and I have a button that should pass the date selected in the datepicker to the Servlet that will use this date as the parameter for a mysql search. How can I pass this date to Servlet? I have tried several examples that I found on the web, but without success.

Button:

<img src="IMG/check.png" style="cursor:pointer" onclick="UpdateGrafico();" />

Datepicker:

<!--datepicker1 -->
   <div class="container" style="width: 100%; 
        margin: 0.5em auto; 
        padding: 1em;
        border: 1px solid greenyellow; 
        border-radius: 0.5em">
    <div class="row">
        <div class='col-sm-3' style="margin-left:10px;">
            <div class="form-group">
                <div class='input-group date' id='datetimepicker1' >
                    <input type='text' class="form-control" id="d"/>
                    <span class="input-group-addon">
                        <span class="glyphicon glyphicon-calendar"></span>
                    </span>
                </div>
            </div>
        </div> 

        <img src="IMG/check.png" style="cursor:pointer" onclick="UpdateGrafico();" />
        <script type="text/javascript">
            $i(function () {
                $i('#datetimepicker1').datetimepicker({
         format: 'DD/MM/YYYY HH:mm'
    });

            });
        </script>

    </div>
</div>
<!--datepicker1 -->
