Handling Feature Flags in a Java EE Application using Togglz

Wednesday, June 26th, 2013

Feature flags are a common technique, often combined with continuous deployment and delivery and they allow us to rollback a specific feature, to create A/B tests or to rollout a specific feature for a specific test group, a specific amount of users or dedicated systems.

In the following short examples I’d like you to demonstrate how easy it is to implement feature flags with the Togglz framework with a few steps in a Java EE environment.

Create Mobile Websites using Java Server Faces and PrimeFaces Mobile

Sunday, January 8th, 2012

The more smartphones and tablets are sold the bigger the need for a mobile version of a modern website. PrimeFaces Mobile helps us developers here  and allows us to quickly create mobile websites that display well on an iPhone, Android, Palm, Blackberry, Windows Mobile and others.

In the following tutorial we’re going to create a web application that is using Java Server Faces 2.1, PrimeFaces 3.1 and PrimeFaces Mobile 1.0 and runs on a simple web container like Tomcat or Jetty.

Creating Portlets using Java Server Faces 2 and Liferay

Tuesday, July 19th, 2011

Portlets are a common technology to create plug&play components for modern web applications and are specified by the Java Community Process in several specification requests.

In the following tutorial we’re going to learn how to create custom portlets and how to deploy and embed them in Liferay, the popular open-source enterprise portal.

In addition we’re taking a look at inter-portlet-communication and how to create portlets using annotations.

Finally we’re building a portlet-state-aware Java-Server-Faces portlet using the  jsf-portlet-bridge mechanism.

Using PrimeFaces to pimp up existing Java Server Faces / JSF 2 Applications

Sunday, November 14th, 2010

In this tutorial we’re going to modify an existing Java Server Faces / JSF 2 web application by adding rich UI components to the existing layout.

Our tool of choice here is the PrimeFaces framework. It offers a wide range of interesting, customizable and (several) Ajax-enabled components that blend very well with JSF1+2  and also a solid documentation that allows a quick integration into existing projects.

Java Server Faces/JSF 2 Tutorial – Step 1: Project setup, Maven and the first Facelet

Saturday, June 5th, 2010

In this short tutorial we are going to build a Java Server Faces Web-Application using JSF2.0, Facelets, Maven and Hibernate as ORM Mapper.

The goals for this first step are: Setting up the project structure using Maven, defining a frame template/decorator and a registration facelet, creating a managed bean and mapping it’s values to the facelet, adding some basic validation, displaying validation errors and finally adding a navigation structure.

In step2 of this tutorial we are going to add persistence using Hibernate, add some security, create a custom UI component and add some AJAX.

The Mojarra JSF implementation is used for this tutorial – perhaps I’m going to post more about the MyFaces implementation in another tutorial.
