Help needed to hook up Google Checkout via [ Google Checkout's HTML API ]

[tomtom]

Hi,
    Can someone please give me some pointer on what i need to do in
order to use google checkout html api integrated into konakart ? 

I believe the actual  google checkout html api form posting will need to happen at
this page:

http://domain/konakart/CheckoutDelivery.do

I assume that i will need to pass whatever info i have at the CheckoutDelivery.do
page as hidden form fields to google when the customer click on the google checkout button.

I took a look at google doc for html api version: http://code.google.com/apis/checkout/developer/google_checkout_html_api.html#integration_overview

and i presume i need to add a form posting integrated to CheckoutDelivery.do page.

==============================
<form method="POST" action="https://sandbox.google.com/checkout/cws/v2/Merchant/1234567890/checkoutForm"; accept-charset="utf-8">

  <input type="hidden" name="item_name_1" value="Peanut Butter"/>
  <input type="hidden" name="item_description_1" value="Chunky peanut butter."/>
  <input type="hidden" name="item_quantity_1" value="1"/>
  <input type="hidden" name="item_price_1" value="3.99"/>

  <input type="hidden" name="ship_method_name_1" value="UPS Ground"/>
  <input type="hidden" name="ship_method_price_1" value="10.99"/>

  <input type="hidden" name="tax_rate" value="0.0875"/>
  <input type="hidden" name="tax_us_state" value="NY"/>

  <input type="hidden" name="_charset_"/>

  <input type="image" name="Google Checkout" alt="Fast checkout through Google"
src="http://sandbox.google.com/checkout/buttons/checkout.gif?merchant_id=1234567890&w=180&h=46&style=white&variant=text&loc=en_US";
height="46" width="180"/>

</form>
==============================

If this is true, can someone please give me some starting pointer on what i need to change ?
I presume i need to make some jsp file changes and some config file changes but before i start to implement it base on my understanding, i like to get some expert advice first before i start.

I do appreciate your help and expertise guidance on this. 
Thanks again for your help on this

Hi Tomtom,

I'm no expert on Google Checkout (GC) but here are some pointers on what you may need to do:

Once you have all of the shipping quotes (CheckoutDeliveryAction) you need to pass these along with the basket information to GC in a form similar to the one you metioned in your post. This form will have to be created dynamically in a JSP. You will need to modify struts-config.xml to change the navigation since you don't want to show a checkout payment and checkout confirmation page.

At this point KonaKart will not have saved the order so if you want KonaKart to keep a track of the order you will need to save it before passing control to GC. Otherwise I suppose you can do all of your order processing through GC and never save any orders in the KonaKart database.

Good luck, and if you get it working please post a link to your web site since it may be of interest to other KonaKart users.

Thanks for the response.

I decided to take this approach which you suggested below:
"Otherwise I suppose you can do all of your order processing through GC and never save any orders in the KonaKart database."

If this is the case, i believe the dynamic jsp changes that need to happen is here:
EditCartBody.jsp

I like to get your expertise on some of the questions that comes up base on this changes above:
a) Is this the right place to integrate GC at the EditCartBody.jsp ? If not, please give me a better suggestion if possible. 

b) Here is what i think the EditCartBody.jsp page would look like:

What's in my cart?
Remove     Product(s)     Qty.     Total
                    Item # 1         2         $1.00
                    Item # 2         1         $2.00

Update Continue-Shopping            GoogleCheckoutBuyButton

Since i'm using google checkout button, how can i still make the "Update" and the "Continue-Shopping" action button work since their
action in the form is different and i can only have one form posting?

I guess i'm not so worry about the "Continue-Shopping" action button since i can have just a link instead of a action button.
I'm more concern of the fact that once i integrate GC in this page, the "Update" action button will not work for the remove item functionality. Any suggestion here will be really appreciated   

GC post action:
<form method="POST" action="https://sandbox.google.com/checkout/cws/v2/Merchant/1234567890/checkoutForm"; accept-charset="utf-8">

Konakart post action form:
<html:form action="/EditCartSubmit.do">
