I have since updated the JIRA with a clarification of what I am trying
to do and have included it here in <JIRA update> tags.
<JIRA update>
Just to clarify one piece of information about this problem:
serviceA and serviceB are totally unrelated. The system composites are
located as follows:
~/tuscany/services/
|
+----->serviceA/serviceA.composite
|
+----->serviceB/serviceB.composite
</JIRA update>
Seems like the problem is that the SCARuntime was designed towards just
having one service loaded at a time. And what I am trying to do is to be
able to load several unrelated services.

Subject: Re: [TuscanySCA CPP] problems trying to load services from
multiple directories at once
I think that them intent is for any composites under the
TUSCANY_SCACPP_SYSTEM_ROOT to be loaded so I think it may be an error to
specify a _PATH that includes or is a subdirectory of the SYSTEM_ROOT.
Maybe we could police this or change the loader to ignore duplicates
from the same location.??
