1 What You Need to Know Liberty in CICS Michael Jones 1er Decembre 2016

2 What is Liberty? IBM WebSphere Liberty Profile is an intelligent Java based web application server Started Life as a lighter edition of the WebSphere Application Server, later moved to it s own distinct product Focuses on having an easily configurable opt-in customisation model, giving you full control over your configuration Integrated into CICS starting with CICS TS V IBM Corporation 2

3 Liberty s Core Concepts Composable Lightweight Fast 2014 IBM Corporation 3

4 Java Enterprise Edition Java Platform, Enterprise Edition (Java EE) is the standard in community-driven enterprise software. Java EE is developed using the Java Community Process, with contributions from industry experts, commercial and open source organizations, Java User Groups, and countless individuals. Each release integrates new features that align with industry needs, improves application portability, and increases developer productivity. Or more concisely, a set of enrichments to Java which bring.. Web technologies Data handling technologies Dependency management 2014 IBM Corporation 4

5 Why use Liberty in CICS? Support for Java Enterprise Edition 6 Web Profile and Java Enterprise Edition 7 web profile and a pool of other Java technologies for enterprise (depending on your CICS level) An easily configurable HTTP endpoint for your applications Ability to closely integrate front end applications with existing CICS programs Can be used to easily and quickly augment your existing CICS programs 2014 IBM Corporation 5

6 Support Roadmap Initial support for Liberty was added in CICS TS 5.1 This basic support included a subset of web technologies, along with RESTful web services and SSL The version of Liberty running in CICS v5.1 is kept upto date with supported Liberty versions. CICS TS v5.1 Features servlet-3.0, jsp-2.0, jsf-2.0 Wab-1.0 jaxrs-1.1, json-1.0 SSL-1.0 Description Servlet and Java server pages for web applications Web applications in OSGi application projects (EBAs) RESTful services and JSON SSL support with Java key stores 2014 IBM Corporation 6

7 Support Roadmap Expanded support for more Java Enterprise Edition features. Includes CICS Security Integration and Type 2 DB2 support Also kept up to date with Liberty supported versions CICS TS v5.1 CICS TS v5.2 Features appsecurity-2.0 jndi-1.0 Description JEE application security, authentication and authorisation Java Naming and Directory services jdbc-4.0 jaxws-2.2, jaxb2.2 WAS support for JDBC and data sources to remote d/b Java web services support 2014 IBM Corporation 7

8 Support Roadmap Support for Java Enterprise Edition 6 Web Profile features Support for Java Enterprise Edition 7 Web Profile features Kept up to date with each stable Liberty release CICS TS v5.1 CICS TS v5.2 CICS TS v5.3 Features JEE 6 Web Profile JEE 7 Web Profile Description Web technologies as described by Java Enterprise Edition 6 Web Profile Web technologies as described by Java Enterprise Edition 7 Web Profile 2014 IBM Corporation 8

Link to Liberty JEE7 Full Platform Enablement of EXEC CICS LINK into Liberty Support for JEE7 full platform specification 2014 IBM Corporation 9

10 Statement of Direction IBM intends to deliver support for Java applications that exploit Java EE 7 Full Platform features when running in the WebSphere Liberty profile that is integrated with IBM CICS Transaction Server for z/os (CICS TS). IBM intends to deliver additional Java EE 7 components and technologies for the CICS TS hosted WebSphere Liberty profile through continuous delivery of new features in the coming months. These additional components and technologies are intended to include support for Java EE 7 Web Profile features, support for JMS 2.0 with IBM MQ for z/os, and the ability to LINK from a CICS TS COBOL program to a CICS TS hosted Liberty application.

11 CICS Liberty Implementation CICS JVM In CICS Liberty is hosted within a JVM server resource Web Client Liberty Web App CICS Resource The JVM server hosting Liberty is managed in the same way any other JVM server To specify a Liberty JVM server instead of an OSGi JVM server, simply add the WLP install directory parameter to your JVM profile The WLP install files come with CICS and are located in your USS home directory 2014 IBM Corporation 11

12 Defining and Installing your Liberty JVM server Start by creating a JVM profile for your JVM server CICS provides a sample JVM profile for Liberty JVM servers called DFHWLP.jvmprofile DFHWLP.jvmprofile CEDA INSTALL JVMSERVER(DFHWLP) You can find this sample under: USSHOME/JVMProflies/DFHWLP.jvmprofile JVMSERVER DFHWLP 2014 IBM Corporation 12

25 The Recommended Liberty Development Environment CICS Explorer is the recommended development environment for all CICS Java environments Includes everything you need to develop Java applications, including the Liberty libraries CICS Explorer comes with the WebSphere Development Tools, which allows you to start a local Liberty server for testing applications IBM Corporation 25

Building Applications You have two choices in how to set up your application Traditional Java Archives Typically archive files, the very basic of which is a JAR, or Java ARchive OSGi

The Liberty runtime allows you to extend these artefacts for the web or similar functionality The Liberty enhancements are called Web Application archive (WAR) and Enterprise Application

26 Building Applications You have two choices in how to set up your application Traditional Java Archives Typically archive files, the very basic of which is a JAR, or Java ARchive OSGi bundle framework applications OSGi provides a service orientated framework for running applications. The Liberty runtime allows you to extend these artefacts for the web or similar functionality The Liberty enhancements are called Web Application archive (WAR) and Enterprise Application archive (EAR). Shares many file extensions with traditional Java. Applications are deployed as bundles which are described my meta information called a manifest. Uses JAR files much like traditional Java, but can also use Enterprise Bundle Archive (EBA) IBM Corporation 26

27 Packaging Applications There are 5 packaging options for the two models Artifact Name Purpose Uses OSGi? Extension Dynamic Web Project Web-enabled OSGi bundle Enterprise Archive OSGi Application Project Simplest container for web based Java projects Simplest OSGi container for web based projects Container for Enterprise Java Beans Container for multiple web enabled OSGi bundles No Yes No Yes.war.jar.ear.eba CICS Bundle CICS resource for all artifacts Yes N\A 2014 IBM Corporation 27

28 Packaging Applications A note on EARs and EBAs CICS Single point of management for logical groupings of bundles or applications EBA Bundles EAR Archives One EBA can contain multiple bundles One EAR can contain multiple applications EBAs and EARs allow you to have one single artifact for those bundles or applications, rather than having one for every single one 2014 IBM Corporation 28

29 Deploying Applications 1 Install a CICS bundle with your application inside it. CICS Bundle JAR/WAR/ EAR/EBA 2 Put your application into Liberty s drop ins directory 3 Add application XML tags to server.xml <application id="wabonly_multiapp_1.0.0" location="/u/michaej/multiwab/wabonly_multiapp_1.0.0.eba" name="wabonly_multiapp_1.0.0" type="eba"/> 2014 IBM Corporation 29
