What are the best-practice / industry standard technologies for the folowing requirements

  1. Allow transfer of business objects from one client / server to another
  2. Language and platform independent
  3. Supports Streaming to alow passing large data (e.g. a connected statefull conversation)
  4. Is Asynchronous in nature (doesn't block, allows monitoring progress)

SOAP workaround

1,2 point on SOAP web services, but 3 and 4 make it a little hard to implement (don't they?)

I was thinking of the following "hack", but I both don't like it, and I'm sure there is a better solution.

To support 3 and 4 the SOAP web service can have methods that pass the data in chunks, e.g.

void startObjTransfer(String objectId);
void addObjChunk(String objectId, ObjData currentChunk);
void endObjTransfer(String objectId);

Where ObjData contains a partial graph of the data, and knowledge of its location in the graph.

to better support 4 a method like this can be used to ask how much progress was made

void getObjTransferProgress(String objectId);

What do you think about the above? isn't there (hopefully there is) a better one? (even non SOAP)

RMI / COM / .NET Remoting / DCOM

Not language independed

CORBA

Well, no.

REST

Not answering 3 and 4, (SOAP + Buzz?)

AJAX / COMETD

Related to question: Asynchronous web service streaming

Not sure how this will work, please explain

Message Queue?

Will that work for this purpose?

    Do you mean language independent or platform independent? Using WCF in .NET would be language independent but not platform independent. – John Saunders Jan 30 '10 at 01:30
  • @John - WCF services will run only on .Net but the client can be on any platform written in any language (C#, Java, PHP, Ruby etc.) http://stackoverflow.com/questions/856368/is-wcf-platform-independent – Pavel Nikolov Jan 31 '10 at 14:38
  • @Pavel: I know. That's why I asked which one he meant. – John Saunders Jan 31 '10 at 23:00

I think Coucho Hessian should fulfill your needs (including streaming, platform independence...). You might also take a look Thrift from the Facebook guys.
