How to load an HTML page locally and email its contents through javamail?

I have an HTML Page whose contents are loaded locally from cookies.

I want to mail the page contents as it is to my gmail account using javamail

My html Page

<html>
<head>
    <script src="js/simplecartcheckout.js" type="text/javascript" charset="utf-8"></script>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
</head>
<body>
                <h2>Order</h2>
                <div class="simpleCart_items" >
                </div>
                <br></br>

            SubTotal: <span id="simpleCart_total" class="simpleCart_total"></span> <br />
    Tax Rate: <span id="simpleCart_taxRate" class="simpleCart_taxRate"></span> <br />
    Tax: <span id="simpleCart_tax" class="simpleCart_tax"></span> <br />
    Shipping: <span id="simpleCart_shipping" class="simpleCart_shipping"></span> <br />
    -----------------------------<br />
    Final Total: <span id="simpleCart_grandTotal" class="simpleCart_grandTotal"></span>
</body>
</html>

When I run this page on localhost its contents are loaded from the data in cookies.

I am trying to send the loaded html page contents as email to my gmail account

But when I put the code in MimeMessage.setContent() method in javamail I receive a blank email without the contents.

I want all contents in my mail, without converting it to any other file format or as an attachment.

Solution

This answer How do I send an HTML email? explains that your HTML should not contain the <html>, <head> or <body>.

Also I'm not sure the script will be supported.
