forwarding a post

[John Pedersen]

Hi,

Can anyone suggest how I can forward a post using servlets?

I have a page with 3 forms on it. The forms are paypal, google checkout, and
one other payment methods.

eg:

 <form method="POST"
    action="
https://sandbox.google.com/checkout/api/checkout/v2/checkout/Merchant/***";
name="gc" >
        <input type="hidden" name="cart"    value="$googleCart">
        <input type="hidden" name="signature"     value="$googleSignature">
        <input type="image" name="Google Checkout" alt="Fast checkout
through Google"
        src="
http://sandbox.google.com/checkout/buttons/checkout.gif?merchant_id=***
              &w=180&h=46&style=white&variant=text&loc=en_GB"  height="46"
width="180">
   </form>

etc

I want to be able to track which of the buttons users click, so I am using a
form like this:

<form method="POST"  >

<input type="image" name="Google Checkout" alt="Fast checkout through
Google"
        src="
http://sandbox.google.com/checkout/buttons/checkout.gif?merchant_id=***
              &w=180&h=46&style=white&variant=text&loc=en_GB"  height="46"
width="180">

<input type="image" src="
https://www.sandbox.paypal.com/en_US/i/btn/btn_buynowCC_LG.gif"; border="0"
name="Paypal" alt="PayPal - The safer, easier way to pay online.">

etc

</form>

Then, depending on which button the user clicks, I want to forward the user
on to google/paypal using POST, adding the parameters such as cart,
signature.

Been playing around with a HttpsURLConnection :

URL url = new URL(
                    "
https://sandbox.google.com/checkout/api/checkout/v2/checkout/Merchant/***";);
            HttpsURLConnection conn = (HttpsURLConnection)
url.openConnection();
            conn.setDoOutput(true);
            conn.setRequestMethod("POST");
            OutputStreamWriter wr = new OutputStreamWriter(conn
.getOutputStream());
            wr.write("name=\"cart\"");
            wr.write("value=\""+encodedCart+"\"");
            wr.write("name=\"signature\"");
            wr.write("value=\""+signedCart+"\"");
            wr.flush();
            conn.disconnect();

I'm not sure if that sends he info to google, but it certainly doesn't move
the user onto google's site.

Can anyone help?

TIA,

John
