Hi, Steve.
First, thanks for clarifying your requirements......
Since you've already done some sockets programming (in Rexx), this will
be very similar.
There are a couple of socket APIs available on CMS, if you don't want to
use the Rexx sockets function package (Adam and I like it, 'cause we
just like to code in Rexx; but your performance requirements may
precludes that...). You can:
1) use the OpenExtensions (I think that's today's name) callable
services from Assembler to work with sockets.
2) use the Reusable Server Kernel tool, which supports the development
of very hight performance TCP/IP based servers, again in assembler.
3) use the LE callable socket functions from a HLL like COBOL.
Good luck.

Communicate: Well, that's the issue. That's one of the things I need
guidance on.
The application would run on VM and request the information from a WAS
server running on Intel.
That information would then be returned to the VM app.
I assumed they would communicate via TCPIP
I've done this using Rexx sockets but in the other direction. i.e. I
have an app. running on an http server running on Linux (running on an
IFL running VM)
using hipersockets, etc.
It requests info from VM, sends it back and displays it on a web page.
But remember, I'd really like to avoid using Rexx sockets. If it is
absolutely the only way to do it, then so be it.

Hi, Steve.
Yes, I done something very similar to this. How are you planning to have
the Java program communicate with he z/VM (CMS-based?) application?
Would the Java/WAS environment be in a different z/OS LPAR or be running
as a guest of z/VM?
This shouldn't be all that hard to do, once we understand the
particulars a bit better.
