2019 March Meeting

When: Tuesday March 12th 11:30 – 13:00

Where: StarSpace46 / Techlahoma 1141 W. Sheridan Avenue

Topic: Microservices with Micronaut

As microservices have exploded on to the scene, so have microservice frameworks. In the JVM world, we have a myriad of options. In an already crowded space, though, a new framework has appeared that is extremely promising. Micronaut is a polyglot microservice framework from the inventors of the Grails framework, supporting Java, Kotlin, and Groovy out of the box. Micronaut ships with support for a wide number of capabilities, including dependency injection, aspect oriented programming, object relational mapping (via JPA or GORM), cloud native features (Consul, Eureka, Kubernetes, AWS, and others), serverless/functions-as-a-service, and many more. It even comes with a testing framework.

In this presentation, we’ll see how to get started using Micronaut using a small subset of those features as we build a simple REST service.
We’ll use JPA for persistence, and secure the application using JSON Web Tokens, all fully tested. At the end of the session, we’ll have a solid foundation for building microservices using this new offering.

Speakers:

Jason Lee

Jason Lee is a Senior Member of the Technical Staff for Oracle working on the GlassFish Administration Console as well as the RESTful Administration interface. Jason has extensive experience working with web-based technologies such as JavaServer Faces and Ajax, as well as many other enterprise technologies based on the GlassFish platform.

Jason has been writing software professionally since 1997 in a wide variety of languages and environments, including Java, PHP, C/C++, and Delphi on both Linux/Unix and Windows. You can read more about what Jason’s working on at his blog.

Most importantly, Jason is married to a beautiful woman and has two sons who, thankfully, look like their mother.John Chesser has been writing Java on the front and back end for 18 years. John focuses on keeping it simple. He has experience writing full systems from scratch and maintaining older systems for companies like Creative Labs Inc. and Powercosts Inc.

Where: StarSpace46  1141 W. Sheridan Avenue

Topic: Essential Tools for Performance Metrics and Troubleshooting

Every developer creating real-world applications will have to eventually troubleshoot code performance issues – sometimes even in Production systems. In this session we will show a couple of essential tools that every Java developer should know about and can use to gather detail performance metrics (CPU, Memory, Threads, Hot Methods, etc.). With the help of these tools you can get to the bottom of tough issues such as bottlenecks caused by locking and memory leaks. We will specifically cover Java Mission Control (JMC), and Eclipse Memory Analyzer Tool (MAT).

Speakers:

Bill Spens is Director of Software Development at Power Costs, Inc. (PCI); He has 10 years of experience troubleshooting Java and Oracle performance and currently focuses on improving processes and efficiency across many agile teams.

John Chesser has been writing Java on the front and back end for 18 years. John focuses on keeping it simple. He has experience writing full systems from scratch and maintaining older systems for companies like Creative Labs Inc. and Powercosts Inc.
