VM/ESA Network Computing with Java and NetRexx

Java is the hot new programming language for the nineties and beyond and
for developing a whole new category of Internet aware applications.
NetRexx 'improves' upon Java by blending the best features of classic
REXX with the object model and semantics of Java and the Java Virtual
Machine execution environment. Together, these languages provide
powerful new tools for enabling VM/ESA systems to fully participate on
both the Internet and on organizations' internal 'intra-nets'. Coupled
with the new IBM Network Station, VM/ESA can now provide a powerful
solution for bringing network aware applications to large numbers of
simultaneous users in a very cost effective manner.

This redbook describes how to install and configure both Java and
NetRexx using the IBM provided installation files and scripts. It also
covers a selection of VM tools that make using NetRexx and Java easier
and less trouble-prone to the applications developer. There is a
detailed comparison of NetRexx to classic REXX to help guide VM/REXX
programmers through the similarities and differences and introduce them
to the novel capabilities of NetRexx. Also included are hints and tips
on good NetRexx design and a wealth of examples of NetRexx application
programming techniques in the CMS environment.

The book culminates with a complete demonstration application, comprised
of a multithreaded CMS server written entirely in NetRexx and a
graphical client, written in a mixture of NetRexx and Java, that may be
run on IBM Network Stations or other Java platforms, which provides
various graphical views of VM performance statistics. Detailed
instructions for configuring a network station environment to support
the execution of such VM/ESA-based applications are also included.
