Stas,
I've thought about it a little more and realized that the code change below,
while required to get the Address and PhoneNumber classes to serialize
properly, is still not sufficient. Body entries are required to implement
Serializer (the exception message is right on the mark), which means you
need a "MethodMessage" or similar class, which would contain a list of
Parameters, to be the body entry.

Stas,
I think the initial problem was really that Message#send does not use a
user-defined type mapping. What you really wanted to do was:
Envelope msgEnv = new Envelope();
Message msg = new Message ();
Body body = new Body();
Vector bodyEntries = new Vector();
...
bodyEntries.addElement(new Bean(Address.class, address));
body.setBodyEntries(bodyEntries);
msgEnv.setBody(body);
** SOAPHTTPConnection st = new SOAPHTTPConnection();
** st.send (new URL (args[0]), "urn:this-is-the-action-uri", null, msgEnv,
smr, new SOAPContext());
This way, the mapping you defined actually gets used to marshal everything.
(Note: I *think* this is true, but I did not actually write/compile/run the
code!)
Assuming this successfully serializes things, I notice that your message
does not specify a method. You've made an Address the body entry, yet what
you really need it to be is a "MethodMessage". This would look like the
"outbound" half of RPCMessage, e.g. the buildEnvelope, marshal,
serializeParams methods. Such a class would produce the envelope you want
your body to have.
