Enterprise Java in past 20 years

• Java EE (currently Jakarta EE)

○ Java EE 5 - May 11, 2006 ○ Java EE 6 - December 10, 2009 ○ Java EE 7 - June 12, 2013 ○ Java EE 8 - August 31, 2017

MicroProfile

• Eclipse MicroProfile is an open-source community specification for Enterprise

Java microservices

• A community of individuals, organizations, and vendors collaborating within an
• pen source (Eclipse) project to bring microservices to the Enterprise Java

community

What is MicroProfile Starter

• MicroProfile Starter generates working sample code for MicroProfile specifications:

○ To lower the learning curve for using MicroProfile specifications ○ To increase developer productivity ○ To deliver solutions faster to the business

• A starter/generator had been discussed by the community many times before

○ Earliest whisper by James Strachan back at Devoxx BE 2016

• An independent community member, Rudy De Busscher, on Aug 21, 2018, attended the

bi-weekly MicroProfile community Hangout call and demoed a prototype that he had developed

• (Rudy was hired by Payara subsequently)
• Starter team was assembled soon after. Starter Beta released on Feb 6, 2019.
• Current team members are from many organizations and communities: Rudy, Karm, YK, Ryan,

etc.

• If you’d like to participate and help us develop the Starter, please post your desire to help us at

microprofile@googlegroups.com to get you looped in ○ Need help developing extensions for IntelliJ IDEA, Eclipse IDE, Netbeans, Eclipse Che

• Examples generator for a

variety of runtimes

• This is NOT just a pom.xml

generator

• Sports REST API for easier

integration

• Best for your first contact

with MicroProfile, using your favourite runtime you are used to

❤ How to contribute ❤

15

• Runtimes implementations

○ Adding your MP implementation - ensure it passes the MP TCKs for the umbrella release and is added to the MP implementations page ○ Improving current runtimes implementations. Are you a Launcher or KumuluzEE fan? Helidon expert? Take a look...

• Contribute to develop more code examples for MP specs

○ Follow these instructions ○ Do a Pull Request on the Starter project ○ Add your implementation or new code examples ○ Test your additions to the MicroProfile starter project ○ Community review, requires 2 acks ○ Merge

What is Quarkus?

• A Kubernetes Native Java stack tailored for GraalVM & OpenJDK HotSpot,

crafted from the best of breed Java libraries and standards

• Great interoperability with containers, small memory footprint
• Toolchain for building Java applications with a lot of heavy lifting done at build

time instead of runtime

A cohesive platform for optimized developer joy:

• Based on standards, but not limited
• Unified configuration
• Zero config, live reload in the blink of an eye
• Streamlined code for the 80% common

usages, flexible for the 20%

• No hassle native executable generation

Build / Dev / Native modes

• You can use Quarkus to build a small uberjar

○ https://quarkus.io/guides/maven-tooling.html#uber-jar-maven ○ Use HotSpot or GraalVM to to run it

• You can work in Dev mode

○ where Quarkus monitors your changed files, quickly recompiles ○ enables hot deployment with background compilation ○ https://quarkus.io/guides/maven-tooling.html#development-mode

• You can use Quarkus to easily create a single statically linked executable

○ Leverages SubstrateVM and Native image from GraalVM toolchain ○ Single executable for particular architecture ○ https://quarkus.io/guides/building-native-image-guide

And now, on to the demos!
