Hi Liu:

Normally a CORBA call will 'block' until it is done.
This is what you are seeing, the second call is not
started until the first call has returned.

If you don't want this behavior, try making the
CORBA calls "oneway", this means that they will not
block until complete, but will return immediately.

(Of course you must be very careful about using
"inout" params with oneway calls).

Hope this helps,
