Re: Maybe if I rephrase the question?

Nathan,

Your assumption that all connections are via TCP/IP is incorrect. If
you
use the native drivers, you will bypass the overhead associated with
TCP/IP.  Some things I would say are an advantage on the iSeries
other than reliability (two servers are not better than one) include
the
ability to set priorities for jobs and threads, the ability to
associate
individual users with a task.

For a single CPU server, what is the advantage of running Java and
Websphere
under OS/400?  Why not just deploy the classes under the Integrated
xSeries
Server, for example?

My understanding is that to access native OS/400 resources (database,
data
queues, programs, etc.), java connects to OS/400 host servers via
TCP/IP.
Isn't that true regardless of whether the Java components are running
under
OS/400, or Windows, or Linux?  The host servers perform their job and
return
results over the TCP/IP connection.  From the point of view of
software
design, it as though Java were running on a different platform anyway.
Right?
