Monday, May 26th, 2014

Using dependency injection and aspect-oriented mechanisms like interceptors allow us to separate cross-cutting-concerns in our Java enterprise application, to control global aspects of our application and to avoid boilerplate code.

In the following short tutorial we’re going to create an aspect-oriented logger to protocol the initiating user, class and method called and the parameters passed to the method and finally we’re adding this interceptor to a sample RESTful web-service by adding a simple annotation.

Arquillian Tutorial: Writing Java EE 6 Integration Tests and more..

Thursday, April 26th, 2012

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.

Creating a sample Java EE 6 Blog Application with JPA, EJB, CDI, JSF and Primefaces on GlassFish

Tuesday, February 8th, 2011

Java EE 6 is out and it indeed offers an interesting stack of technologies. So in today’s tutorial we are going to build a small sample web application that builds on this stack using Enterprise JavaBeans, Java Persistence API, Bean Validation, CDI and finally Java Server Faces and PrimeFaces.

The application we’re going to develop is a simple blog app that allows us to create new articles, list them and – finally delete them. We’re also covering some additional topics like JSF navigation, i18n, Ajax-enabled components and the deployment on the GlassFish application server.
