HELP! Unable to connect two orchestrations

| HELP!
I´m a student on my final thesis and despairingly fighting with the BizTalk
Server 2004.
All I wanna prove for my thesis is, that you can connect two different
orchestrations (that should originally run on two machines, but for an
example it is okay to show it on one machine) and exchange information
between them.
But I cannot get it to work - doesn´t matter what I do. Usually I wanted to
connect them through webservices. But all the time I do this I get some
undefinable SOAP exceptions. So I´m already glad if I can connect them in any
way, because time is running away and the final date for disposal is coming
closer and closer. I tried to understand the background through the Microsoft
SDK examples, but my scenario seems to be a little bit different:
Two different orchestrations (.odx-files) should exchange some information.
That´s all! In my example it is a simple order. The main process receives an
order (via file) and passes it to the second process (via webservices if
possible). Then the second process returns the number of items, that it can
deliver to the mainprocess. That´s it!
I thought, this shouldn´t be too difficult, but I were wrong. I already
integrated an external webservice in my process. That was no problem. But I
cannot get my own processes and webservices to work. Is there anyone out
there, who can help me? Because I´m all working on my own and tried so many
things. Finally I don´t now what to do else!
Thank you
Thomas

| If I understand what you have done so far - you are ideally looking to get
one orchestration communicate with another orchestration, where the second
orchestration is exposed as a web service? If this is what you are trying
to do, please elaborate on what problems and errors you had in trying to set
this up.
Alternatively, you can have the first orchestration call the second one with
the Call Orchestration (synchronous) or Start Orchestration (asynchronous)
shape in the first orchestration. To pass a message between the 2, have the
second orchestration setup with a message parameter:
1. In Orchestration View, right-click Orchestration parameters and add a new
message parameter.
2. Set this message parameter up in the same way you would normally create a
message variable.
3. You will also not require a start Receive shape in the second
orchestration, so delete your starting receive shape.
4. In the first orchestration, you should be able to set the properties of
the call / start orchestration shape to call the second orchestration, and
you should be able to set the input parameter of the second orchestration
with a message variable from the first orchestration.
Hope this makes sense.
Another option is to have the first orc send your message to a port marked
as "Direct" instead of specify now/ later, and in your second orchestration
have the receive port shape marked as Direct as well. This will allow the
first orc to send the message to the Message Box, and the second
orchestration can then subscribe to that message from the Message Box.
