-d'n'd something from facebook to servlet/jsp
-open web.xml

=> there's nothing added but following code should be there:

    <servlet>
        <servlet-name>FacebookSocialNetworkingServiceLogin</servlet-name>
        <servlet-class>org.netbeans.saas.facebook.FacebookSocialNetworkingServiceLogin</servlet-class>
        <load-on-startup>1</load-on-startup>
        </servlet>
    <servlet>
        <servlet-name>FacebookSocialNetworkingServiceCallback</servlet-name>
        <servlet-class>org.netbeans.saas.facebook.FacebookSocialNetworkingServiceCallback</servlet-class>
        <load-on-startup>1</load-on-startup>
        </servlet>
    <servlet-mapping>
        <servlet-name>FacebookSocialNetworkingServiceLogin</servlet-name>
        <url-pattern>/FacebookSocialNetworkingServiceLogin</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>FacebookSocialNetworkingServiceCallback</servlet-name>
        <url-pattern>/FacebookSocialNetworkingServiceCallback</url-pattern>
    </servlet-mapping>

same issue is there for anything from flickr

btw: Jeff, would it be possible to add a listing or screenshot of web.xml to the tutorial?
