        Right.

        I feel uncomfortable that you are re-implementing a part of
bonobo-activation's client code in Java - but if that's the only way for
you it seems reasonable to me.

        Ok - that sounds fine; when you say 'script' what do you mean ?
you see, it's all very well having a sort of 'System.execute' approach to
launching the server - but currently the locking to ensure you only get
one server is all done in the client side - ie. the C library code. It
would be pain to replicate it and get it right in Java, IMHO.

        So; if your script could execute a little C program, that we
always install that'd be great; eg. if you run bonobo-activation-run-query
with no args, that will ensure ( by the time it completes ) that the
server is correctly started up.

        For now it might be worth simply copying the private IDL interface
into some private place inside the Java impl.

        HTH,

                Michael.
