Thu, 30 Mar 2017 00:00:00 +0200

Drools is a slim Business Rules Management System (BRMS) solution with different integrations and tools available.

In the following short snippet I’d like to demonstrate how to integrate a simple rule engine into an application using this library.

Dependencies

Using Gradle here we only need to add one dependency for drools-compiler to our project’s build.gradle. In addition, we’re adding a task to execute our application.

Arquillian Tutorial: Writing Java EE 6 Integration Tests and more

Thu, 26 Apr 2012 00:00:00 +0200

Now that the long awaited stable version of the Arquillian framework is released I wanted to demonstrate some interesting features of this framework that really eases writing and running of integration tests for Java EE 6 applications in many different ways.

In the following tutorial we are going to create some real-world examples using Enterprise JavaBeans, Contexts and Dependency Injection, the Java Persistence API and we’re finally running Drone/Selenium tests against a JEE Web Application that is using Java Server Faces.

Hibernate Search Faceting: Discrete and Range Faceting by Example

Mon, 26 Mar 2012 00:00:00 +0200

In today’s tutorial we’re exploring the world of faceted searches like the one we’re used to see when we’re searching for an item on Amazon.com or other websites. We’re using Hibernate Search here that offers an API to perform discrete as well as range faceted searches on our persisted data.

Maven Dependencies Needed

For simplicity’s sake am I going to use an HSQL database for persistence, in addition the dependencies for hibernate-entitymanager and hibernate-search (of course) should be added to your pom.xml
