Suppressing signon prompt for AS400 connection from Windows

I have a Java process running on a Windows NT Server which runs 24*7 (or as
close as Windows allows!) and waits for requests placed on an iSeries
(AS400) data queue.

During maintenance periods on the AS400 the connection will drop and I want
the Java process to keep trying to connect until successful.

In my tests running in DOS I have found that the Java throws up a signon
prompt if, for instance, the user or password is wrong but when running as a
service there is nowhere for the prompt to appear (or be asnwered) and so
the process hangs.

Does anyone know if there is a way to suppress this prompt when using
AS400.class to connect? Although the user/password is not going to change I
am worried that if connection is attempted while the AS400 is coming up that
a similar unanswerable prompt will come up and effectively block the Java
process from reconnecting.

Regards,
Tim Fenton
