There is no standard way of implementing a directory of XML-RPC services. There have been ad hoc attempts to provide such a service but I don't think they are widely used. In XML-RPC you know your endpoints and you know what the endpoint expects. You don't have discovery or dynamic binding. You might be interested in http://www.oreilly.com/catalog/progxmlrpc/ and http://www.oreilly.com/catalog/progwebsoap/ as two views of how to implement Web services. If you wanted to use an asynchronous messaging service as a transport mechanism (e.g. IBM's MQ series) then SOAP has the support for this built in. XML-RPC does not (though http://www.jabber.org/jeps/jep-0009.html is an example of an extension which kind of does this). If you wanted to pass a set of objects linked in an arbitrary graph then SOAP will (sort of) let you do it. XML-RPC will not. John Wilson The Wilson Partnership http://www.wilson.co.uk
