hi Mark,

you will need some WSDL2Java tool as it is not included in XSOAP.
i think AXIS has such too that can work also from inside ANT.

that is correct - intention is to have look&feel similar to RMI.

this is already optional. you can write client accessing any SOAP
service using XSOAP (see for example HelloClient) the only
things you need is interface and optionally mappings if you want
override request/response names and parameter names
(example how to do this is in Google sample):

SomeServiceInterface  ref = (SomeServiceInterface ) secureServices.createStartpoint(
                    location,  // service location like http://host:port/portName
                    new Class[]{SomeServiceInterface .class}, // remote service interface
                    "urn:hello:sample", // endpoint name
                    soaprmi.soap.SoapStyle.IBMSOAP,
                    "" // SOAPAction
                );
and you can call any method from SomeServiceInterface on ref.

if you want to create service accessible by other SOAP toolkits and
your service object does not extend RemoteObject or implement Remote
than use this:

        soaprmi.server.Services services = soaprmi.soaprpc.SoapServices.newInstance(port);
        services.setMapping(soaprmi.soap.Soap.getDefault().getMapping());
        soaprmi.port.Port port = services.createPort(
                portName, // give some name for service so it is visible http://host:port/portName
                ifaces, //interface that you want your object to expose
                obj // your object
            );
          soaprmi.Remote ref = services.createStartpoint(port);

where ref is actual remote reference to object that is now available as SOAP service
(this reference can be used to in RMI calls to pass by reference instead of by value)

hope it explains it.

thanks,
