Download the most recent patch titled googleCheckout.patch from OFBIZ-71

Apply the patch to your development deployment. This will create several folders and files under hot-deploy/googleCheckout

SSL

Since we will be consuming services from Google over secure socket layer (SSL) we will need to add two certificates from google to our trusted key store, otherwise our call to Google will fail with the following error:

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Obtain and Compile InstallCert.java

Andreas Sterbenz created a small program that will obtain the ssl certificate from a website and place it into keystore in the current directory. There is probably an easier way of doing this. This is just the first answer I came across that worked.

Download the program from Andreas's Blog.
Compile
% javac InstallCert.java

Obtain SSL Certificates

Obtain the SSL certificate for sandbox.google.com
% java InstallCert sandbox.google.com
Obtain the SSL certificatate for checkout.google.com
% java InstallCert checkout.google.com

Export Certificates to file

Export the certificate for sandbox.google.com from the keystore created by InstallCert

% keytool -export -file sandbox.cer -alias sandbox.google.com-1 -keystore jssecacerts -storepass changeit

Export the certificate for checkout.google.com from the keystore created by InstallCert

% keytool -export -file checkout.cer -alias checkout.google.com-1 -keystore jssecacerts -storepass changeit

Copy both certificates to framework/base/config/

% copy *.cer %OFBIZ_HOME%/framework/base/config

Change into the correct directory

% cd %OFBIZ_HOME%/framework/base/config

Import Certificates into OFBiz Trust Store

Import the certificate for sandbox.google.com into ofbiztrust.jks

% keytool -import -alias sandbox.google.com-1 -file sandbox.cer -keypass changeit -storetype jks -keystore ofbiztrust.jks -storepass changeit

Import the certificate for checkout.google.com into ofbiztrust.jks

% keytool -import -alias sandbox.google.com-1 -file sandbox.cer -keypass changeit -storetype jks -keystore ofbiztrust.jks -storepass changeit

Configure

Configurations are don in hot-deploy/googlecheckout/config/googleCheckout.properties

##your merchantId - sandbox will be different than live

merchantId - obtain from checkout.google.com/sell
merchantKey - obtain from checkout.google.com/sell
editCartUrl - OOTB, should be http://yourDomainName/ecommerce/control/viewcart
continueShoppingUrl - should be http://yourDomainName/ecommerce
xmlTemplateUri - default should work, if you want to change the screen, this makes it easier
requestPhone - true/false do you want to make a phone number mandatory in order to place an order
##Production URL
#basePostUrl = https://checkout.google.com/cws/v2/Merchant/
this has changed since the last patch
##Sandbox URL
basePostUrl = https://sandbox.google.com/checkout/cws/v2/Merchant/
checkout - currently not implemented
request - should not be changed
diagnose = currently not implemented

Use

After updating the properties file, restart OFBiz

in your ecomerce application, create a request-uri; for example:

<request-map uri="google">
  <security auth="false" https="false"/>
  <event type="service" invoke="transmitRequest"/>
  <response type="view" name="success" value="google"/>
</request-map>

create a view-map that points to the redirect screen in the google component:

<view-map name="google" type="screen" page="component://googlecheckout/widget/GoogleCheckoutScreens.xml#redirect"/>

place an link with the google checkout button that points to your google uri next to where ever you have a checkout link
<a href="<@ofbizUrl>google</@ofbizUrl>"><img src="googleButton.gif"/></a>
