Hello, I need to find a way of developing WS that can handle attachments and also be platform independent(process requests from either .NET or Java client). I've already had a look at SAAJ, but from what I read (and from it's name) it doesn't seem to be platform independent. I also saw MTOM mentioned couple of times. Could someone advice what's the best technology available that can be used in this case? Any references to docs and source would be very useful also. Thanks.
