I finally got a chance to take a look at this again. Fixing the servlets was
easy. 

Just needed to uncomment servlet-mapping in web.xml


    <servlet-mapping>
        <servlet-name>invoker</servlet-name>
        <url-pattern>/servlet/*</url-pattern>
    </servlet-mapping>

I did a search and the first thing that came up was my e-mail so figured I
should include the answer =)
