Developing plugins for Liferay DXP with Maven

A new major version of Liferay has been release past May with a lot of new features. One of the most important is related to plug-ins architecture. Basically Liferay is a web application running in a Java EE application container where plug-ins were built as separate web applications. But DXP introduces a module framework based on the OSGi architecture.

But… What it is OSGi? As defined by OSGi Alliance (the organization in charge of this specification): The OSGi technology is a set of specifications that define a dynamic component system for Java. These specifications enable a development model where applications are (dynamically) composed of many different (reusable) components. As the aim of this article is not the OSGi architecture but how it is implemented within Liferay, we are not going to deepen in OSGi specification.  In fact, you do not need to be very familiar with all the OSGI architecture for develop plug-ins for Liferay DXP. You only need to understand this 2 concepts: modules and components.

Making your life easier with Sass

Preface

When I entered my current project one of the first things I noticed was it used stylesheet languages for its styles. “Yay!”, I thought. But then I opened up one of those files and found nothing but plain vanilla CSS inside. It was the same for most of them. No nesting, no variables, no mixins, no inheritance, no operators… Well, you get the idea. I won’t judge anyone and I’d rather believe those who wrote them didn’t use them just because they didn’t know how to. So I thought it would be interesting to write a short article explaining the basics of them.

Angular component method, the natural evolution

One of the cool things that we “were/are/will be” using while coding our front applications with AngularJs is the option to use directives to create our own reusable components. Basically, the main idea of the component was (…and is …and will be) to have reusable elements that brings their own encapsulated functionality and also the ways to manipulate the data they need.

Introducing Spring State Machine

Usually, the first problem that must be solved in the implementation of a software project is to design a well-formed application architecture. Alongside this, core processes must be recognized together with application states as well as the depth of their interactions. There are many ways and methods to achieve this. In case a project meets one of these criteria, it is probably a good candidate for managing the states with a state machine:
