Dual jar/war build for Spring Boot

The great thing about Spring Boot is no need for an external servlet container. All that is needed reside inside a single runnable JAR file. In a very few steps, development of a new application can be started without installation or configuration of any additional software. Yet, sometimes you might want to deploy your application to some server as a regular WAR file. For instance, you convert an existing application and want to keep your continuous delivery pipe untouched or a particular container is enforced by a company’s policy. The reason for building a WAR file may vary across teams, but for development purpose a simple executable JAR file with an embedded server might be preferable.

It’s been almost two years since Java 8 was officially released and many excellent articles about new enhancements and related best practices have been written through that time. Surprisingly, one of the more controversial topics amongst all the added features is the Optional class. The type is a container, which can be either empty or contain a non-null value.

Although the definition of the type on Javadoc is quite descriptive, when it comes to identifying valid use cases it’s getting more problematic.

This article has also been published on DZone.

ES2015 – Ready for development

There is no doubt ES2015 (formerly known as ES6) is one of the top technologies for the foreseeable future and it’ll shortly become a common keyword in front-end job descriptions. Even though browser support for the latest JavaScript update hasn’t been finished yet, you can start learning it by practice right away thanks to Babel syntax transpiler. Studying the specification can be certainly beneficial, but if drilling the material is a preferable method for you to acquire knowledge, Babel is the tool that you’re looking for. In this post I’m going to show how to prepare a basic development environment for ES2015 using Gulp and Babel with automatic source compilation. Enough for the introduction, let’s get the ball rolling.

JEE and the myth of portability

Have you ever been in that conversation in which you had to choose between two or more frameworks/libraries and one of them was so-called JEE standard? Usually a person who advocates for it explains that thanks to standardized API it’s possible to switch the implementation to any vendor whenever needed without a worry that something in our application breaks. In theory, it sounds tempting, but does practice prove it? I’m going to focus on simple case using JAX-RS to verify the assertion.
