  Added:       jk/java/org/apache/ajp/tomcat4 JkServlet.java
  Log:
  Initial attempt to use the Ajp WAR file in 4.0.
  The servlet will configure the ajp connector, using standard web.xml settings.
  
  The main benefit of using WARs is that it'll be much easier and cleaner for users
  to upgrade and install extensions in the server ( and maybe use the 'standard'
  tools for configuration ).
