Reactor by Example
Reactor, like RxJava 2, is a fourth generation reactive library launched by Spring custodian Pivotal. It builds on the Reactive Streams specification, Java 8, and the ReactiveX vocabulary. In this article, we’ll draw a parallel between Reactor and RxJava, and showcase the common elements as well as the differences.

How Java Developers Can Use the Wiremock Framework to Simulate HTTP-Based APIs
A common syndrome in development shops today is the repeated creation of over-the-wire stubs and mocks for testing. In this article Wojciech Bulaty covers how Java developers can avoid reinventing the wheel and leverage Wiremock to build over-the-wire HTTP(s) stubs.

Java 9, OSGi and the Future of Modularity (Part 2)
The flagship feature of Java 9 will be the new Java Platform Module System (JPMS). Given the maturity of OSGi there were technical, political and commercial reasons why another Java module system will soon exist. In this article we compare the two from a technical perspective and see how JPMS and OSGi can work together.

RXJava by Example
In the ongoing evolution of paradigms for simplifying concurrency under load, the most promising addition is reactive programming, a specification that provides tools for handling asynchronous streams of data and for managing flow-control, making it easier to reason about overall program design. In this article we overcome the learning curve with a gentle progression of examples.

Using Templates to Transform Web Service Results into Markup
The HTTP-RPC open-source Java framework returns results in JSON by default, but can use the CTemplate system to respond with custom markup. In this article, Greg Brown shows how simple annotations can be used to automatically respond to a web service in any markup (HTML, XML, CSV, etc.).

JUnit 5 - An Early Test Drive - Part 2
JUnit, Java's most ubiquitous testing framework, is getting an update. In part one of our JUnit 5 coverage, we looked at how we got here and wrote some preliminary tests. In part two, we take a closer look at how to run tests and at some of the very cool new features JUnit 5 brings to the table for us developers.

Working with Multiple Databases in Spring
Accessing multiple databases in enterprise applications can be a challenge. With Spring it is easy enough to define a common data source, but once we introduce multiple data sources things get tricky. This article demos a technique for accessing multiple databases in Spring Boot applications easily and with minimum configuration.

JUnit 5 - An Early Test Drive - Part 1
JUnit, Java's most ubiquitous testing framework, is getting an update. Yes, JUnit 5 is a complete rewrite that decouples "JUnit the Platform" from "JUnit the Tool" and makes the platform available to other testing frameworks, which might very well redefine the future of testing on the JVM. More than that, it evolves the API and has a very promising extension model.
