I have a simple form that uses jquery and a servlet. The jquery makes an ajax call to the servlet, the servlet makes some server side calculations, then displays the result

$('#post_form_jason_data').click(function() {
$('#myform').validate({ 
    rules: {
        txtwtrt: {
            required: true
           // email: true
        },
        tax_name: {
            required: true,
            minlength: 5
        },
    tax_rate: {
            required: true
            //minlength: 5
        }
    }
});
alert('insert the value');
if (('#myform').valid()){


        $.ajax({
            url: "swt_tax_add.html",
            type: 'POST',
            data : $('#myform').serialize(),                
            success: function(msg) {
                window.location.href='swt_tax/?st=1';
                $('#message').html(msg);            

            }

        });
    }

        return false;
    });
