GSE Nordic 2015 CICS Java – Beauty and the Beast After giving sessions about Java in the past few years that tell system programmers they should do Java on IBM z Systems and that Java is just like every other language, this session tries to explain why Java is a bit different in operating and handling. We will compare COBOL/PLI/Assembler with Java and provide insight into how the Java technology works on z Systems. Come along if you want to find out the answers to questions such as: Why can't you phase in a Java program? What does the JIT compiler do and how does it work? What is the development process of Java applications? How do I debugging and logging in Java applications?
Flex For Java Architects Ledroff Breizh Jug V Blog CcFrançois Le Droff
I had the chance to present at the BreizhJUG (a Breton Java user group) a session named "Flex for Java Deveoppers".
A crowd of almost 100 happy Java developers and architects was willing to know more about Flex.
I had an an hour and half to cover :
*
a basic presentation of the flash and AIR platforms,
*
cool UX flash/flex/AIR demos
*
the latest great features of flash 10
*
and flex, and its ecosystem from a Java developer perspective (mvn framework, testing libraries, building and quality tools, blazeds, lcds)
I ended up the session presenting fna maven archetypes

This presentation was given by Ishad M. Barot, Client Technical Professional, India(West) during Impact India 2012 on the 1st of June at Mumbai. It focuses on how businesses can save time and efforts using the WebSphere Application Server. WAS is much more than just being Open Source
Java technology allows programs to run on a variety of hardware platforms, including the mainframe computing platform epitomized by z Systems. The z Systems zOS operating system has a set of unique capabilities, and IBM SDK for Java provides a set of high performance Java APIs complemented by z/OS specific APIs for applications that require deep integration. This talk shows how IBM makes use of the z/OS platform to deliver world-class runtimes on the world leading mainframe.
Originally presented at the z/OS bootcamp in Hursley, 2015

Java EE 6 : Paving The Path For The FutureIndicThreads
“The Java EE platform is getting an extreme makeover with the upcoming version ? Java EE 6. It is developed as JSR 316 under the Java Community Process.
The Java EE 6 platform adds more power to the platform and yet make it more flexible so that it can be adopted to different flavors of an application. It breaks the ‘one size fits all’ approach with Profiles and improves on the Java EE 5 developer productivity features. It enables extensibility by embracing open source libraries and frameworks such that they are treated as first class citizens of the platform.
Several new specifications such as Java Server Faces 2.0, Servlet 3.0, Java Persistence API 2.0, and Java Context Dependency Injection 1.0 are included in the platform. All these specifications are implemented in GlassFish v3 that providesa light-weight, modular, and extensible platform for your Web applications.
This session provides an overview of Java EE 6 and GlassFish v3. Using multiple simple-to-understand samples it explains the value proposition provided by Java EE 6. “
Full Java EE 6 support, great developer experience, multiple yet simple admin tools, embedded mode, mutli-language runtime, OSGi modularity, ... The GlassFish set of feature reads like the roadmap of our closest competitors. See how they can work for you. Today.
