I concur, but think longer term. You may want an all java shop this month, but a year from now you may need to connect to the services from ASP.net, a win32 app or something similar. Example: I am writing a COM object to use the SOAP toolkit to talk to my Java service, for better integration with win32 apps that support scripting. I am doing a lot of work on that client side to make sure the caller of the com object has a simple life (they just name a file to upload and a sender email address), I do the work of creating the xml job ticket, sending that and the attachment. If I'd written a java only web service, I would not be able to integrate my web service with the win32 apps is if I hadnt crippled parts of the API to work with interop. > I can easily see the effect of mismatched Java versions causing > headaches.

I dont think that justifies marshalling java objects over the wire. As an aside, i have done that in the past in a different context (multicast IP transmittal of stuff). Once you move to interoperable XML you get more opportunities to do interesting things, believe me -steve
