My understanding of the use of sockets to interface with native resources
was based on reading.  Not completely assumption ;-)

If os/400 Java and native components are not communicating via sockets, then
what?  Memory pointers?

By "native drivers" are you referring to the record level access support
provided in the iSeries Toolkit?

I'd like to understand the reliability issue better.  It seems that an
integrated xSeries server would be quite reliable (from a hardware
perspective).

But I wonder about the reliability of the JVM under Windows or Linux.  One
way to destabilize Windows is to concurrently run a lot of different
software
(executables, DLLs, and activeX controls).  But that's not the same as
concurrently running a lot of classes within a single JVM.  In one case the
OS is managing (trying to, anyway) the workload.  In the other case the JVM
is managing the workload.  Is the OS/400 JVM more stable than one running
under Windows or Linux?

Is that important if you're just running Servlets, JSPs, and Beans under
Tomcat?
