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.
