Actually, you can. It's just a small matter of coding. :) It's true that SOAP provides no standard way of "boxcarring" multiple requests, partly because it's a complex problem. For starters, how do you deal with errors? Should you treat the whole package of N requests as a transactional unit? Should you stop processing if request 2 of 5 fails, or process everything and boxcar up all the responses including faults? And then of course you need to deal with the fact that there's only one shared SOAP header between all the requests....
Despite all this, nothing in SOAP actually prohibits you from doing it, and if you can force certain limitations (i.e. no SOAP headers, and no stateful requests that rely on the outcome of earlier requests, and the most important one: you must be in control of both sides of the wire), it's quite achievable. If you're using Axis2's code generation / stub capabilities, this isn't easy, since the logic in the generated code absolutely assumes that each operation is in control of the whole SOAP envelope. (*) But if you're using the dynamic APIs and passing OMElements around, this is actually pretty straightforward - you just wrap up your requests in a wrapper element, and then unwrap them on the other side to process them. There are tricky questions like how to best deal with faults, but that's up to you. To sum up - is there a standard way to do this? Definitely not. But you can certainly custom-code one (and if you did a good job, we might even include it in future versions of Axis2). Regards, --Glen (*) Even then, you might be able to write an Axis2 Module that intercepts the individual requests (blocking each on an individual thread), collects them together, and then based on some kind of "openBoxcar() / sendBoxcar()" API, sends them out. But this would involve some tricky/ugly code.
