client ip address example

[Kimberly Nicholls]

I am trying to use the client ip address example here: 
http://ws.apache.org/xmlrpc/faq.html#client_ip, but it doesn't compile:

   [javac] <my path>/MyXmlRpcServlet.java:34: cannot find symbol
   [javac] symbol  : method 
newRequestProcessor(java.lang.Class,org.apache.xmlrpc.XmlRpcRequest)
   [javac] location: class 
org.apache.xmlrpc.server.RequestProcessorFactoryFactory.RequestSpecificProcessorFactoryFactory
   [javac]                     (RequestInitializableRequestProcessor) 
super.newRequestProcessor(pClass, pRequest);
   
[javac]                                                                     
^
   [javac] <my path>/MyXmlRpcServlet.java:35: init(<my package 
path>.MyConfig) in <my package 
path>.RequestInitializableRequestProcessor cannot be applied to 
(org.apache.xmlrpc.XmlRpcRequestConfig)
   [javac]                 proc.init(pRequest.getConfig());
   [javac]                         ^
   [javac] <my path>/MyXmlRpcServlet.java:39: 
setRequestProcessorFactoryFactory(org.apache.xmlrpc.server.RequestProcessorFactoryFactory) 
in org.apache.xmlrpc.server.AbstractReflectiveHandlerMapping cannot be 
applied to (org.apache.xmlrpc.server.PropertyHandlerMapping)
   [javac]         mapping.setRequestProcessorFactoryFactory(mapping);
   [javac]                    ^
I can't find any other information on what this is supposed to be 
doing.  Is there an updated version of the example somewhere?
