What steps will reproduce the problem?
1. Deploy spring MVC example
2.
3.

What is the expected output? What do you see instead?

Please provide any additional information below.

These were the changes I have done:

1. Create my oauth keys (Only Testing Google Provider):
Target URL path prefix:: http://dev.betterinvite.com/socialauth-spring-demo
OAuth Consumer Key: betterinvite.com
OAuth Consumer Secret: (My Oauth Consumer Secret)

2. 'Modified the following lines in the properties.xml':

properties.xml
-------------   
<util:properties id="socialAuthProperties">
    <prop key="www.google.com.consumer_key">betterinvite.com</prop>
    <prop key="www.google.com.consumer_secret">(My Oauth Consumer Secret)</prop>

3. Modified the following lines in the root-context.xml

root-context.xml
----------------------
    <bean id="socialAuthWebController" class="org.brickred.socialauth.spring.controller.SocialAuthWebController">
        <constructor-arg value="http://dev.betterinvite.com/socialauth-spring-demo" />
        <constructor-arg value="authSuccess.do" />
        <constructor-arg value="jsp/accessDenied.jsp" />
    </bean>

4. Changes in tomcat:

    - Traffic sent to the 80 port is forwared to port 8080 (tomcat).
    - Tomcat server name modified to 'dev.betterinvite.com' (via hosts file and server.xml file).

Thanks for your consideration

I found that by going into this page 
https://accounts.google.com/issuedauthsubtokens and revoking app and then 
trying again did work for me. Not sure why!
