No. You cannot invoke multiple webservices in one single HTML request !

Yes, but may not be the way you think.
First, exactly what do you want to accomplish?
Why do you bother doing things like this? Why can't you call multiple
WS requests?
Ok, enough. So, with WS, it's possible to re-use HTTP request, that
is not to close it. In Axis, there is a way to indicate that. Doing
this definitely save performance for a large number of requests to cut
down on the number of connection overhead.
The good news is that you only change a flag or two, and you don't
have to do non-sense hacking stuffs, which I suggest don't do it.

Re: Is possible to invoke multiple webservices in same http request?

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.
