HARNESSING Java in CICS
Getting started with architecting Java Enterprise Edition in CICS Transaction Server

A

t its core, CICS* Transaction Server (TS) is a mixed-language application
server that underpins enterprises worldwide. It has a long history of
supporting a wealth of languages, and in the last few years this support
has grown once again.
Mark Hollands
is a software
engineer on
the CICS
Transaction Server
development team.

Building on the Java*
functionality available through
the CICS JVM server technology,
CICS TS V5 enables application
developers to create enterprisegrade Java applications that can
be hosted in CICS TS.
This article introduces
Java Enterprise Edition (EE)
in CICS TS and explains how
you can start architecting
new solutions that harness
this technology.

Why Use Java EE
Applications in CICS?
Java EE gives a developer a
range of tools with which to
build new applications. From
developing representational state
transfer web services to database
access and transactional
support, Java EE delivers what
enterprise developers need above
and beyond the capabilities in
Java Standard Edition (SE) and
other languages.
When hosted in
CICS TS, developers can build
applications that harness the
features of Java EE and integrate

them with the systems of record
that host their core business.
Collocation of application and
data can greatly reduce the
complexity of the application
architecture and exploit local
z/OS* resources managed in
CICS TS. This z/OS exploitation
is also applicable to the existing
infrastructure supporting your
applications, taking advantage
of z/OS and CICS TS high
availability (HA), disaster
recovery and backup plans.
In addition, eligibility for
Java applications hosted in
CICS TS to run on IBM z Systems*
Integrated Information
Processors or in CICS TS Value
Unit Edition makes Java in CICS
TS an attractive platform for
Java applications.

Introduction to Java EE
Applications in CICS
To understand Java EE in
CICS TS, it's important to
understand IBM WebSphere*
Liberty Profile (Liberty), which
is a lightweight, composable
and dynamic Java EE server

runtime. Liberty allows server
administrators to pick-based on
the needs of their applications-
which features of Java EE
they want to include in their
environment. This flexibility
results in greatly improved start
times (compared to traditional
WebSphere Application Server),
meaning a Liberty server can
initialize in seconds. Liberty
configuration is also dynamic,
so it can be updated on the fly
without restarting the runtime.
Liberty itself is multiplatform.
The Liberty runtime was added
to CICS in CICS TS V5.1. Using
JVM server technology, you
can configure a JVM server
resource to host a Liberty
runtime (configurable in a JVM
profile on z/OS File System,
or zFS). This Liberty runtime
is then configured using
a single configuration file
(server.xml) and integrates with
the deployment mechanisms of
CICS bundles and CICS cloud
applications. It also integrates
with built-in deployment models
available through Liberty.
