JSR-299 CDI Interceptors for Spring Beans

Another early release of a Spring-CDI module, this time it's the interceptor pattern implementation. It implements a JSR-299 compliant interceptor binding model for Spring managed beans. We will use that in our business applications for cross-cutting-concerns.

JSR-299 CDI Decorators for Spring beans

This blog is about my new Spring-CDI modules effort. It's pupose is to make useful CDI patterns like decorators or interceptors available to a Spring application. I do believe that the explicit pattern implementation in CDI is very useful. It makes it obvious and simple to use patterns for not so experienced developers. Therefore I decided to investigate how to make those patterns and the corresponding CDI annotations available for Spring managed beans. Here is the current status of my work. If you're interested and you have some time left, take a look or try out my early version of the Spring-CDI decorator module. The set-up is straight forward. You'll find all you need below.

More Git beginner commands

In my other blog post I introduced 10 important Git commands. This blog is a listing of additional usefull commands when working with Git.

Top 10 commands for the Git newbie

If you're new to Git you will recognize that some things work different compared to SVN or CVS based repositories. This blog explains the 10 most important commands in a Git workflow that you need to know about.

Integration testing scoped beans in CDI 1.0 and Spring 3.1

In this blog post I describe how to do integration testing with scoped beans in Spring and CDI. Everything is illustrated with small code samples. Integration testing with scopes is not particular easy. Imagine a bean that lives in the session scope, like UserCredentials. In an integration test you typically have no HttpRequest or HttpSession to work on (at least if you are not doing tests that include your user interface). Therefore you need some infrastructure for integration testing. With both technologies it is a little puzzling to get this infrastructure going. Get your own picture of it.

Custom scopes in CDI 1.0 and Spring 3.1

This blog post describes in short how to implement custom scopes in CDI using Weld 1.1 and Spring 3.1. To get basic information on scoping see the Spring reference or the Weld reference respectively.

Setting up a Java EE 6 development environment

This tutorial explains in short how to set-up a typical environment to develop Java EE 6 based applications. There is no prerequesite to this tutorial other then a working Windows XP client with sufficient CPU power and memory. During the tutorial we will need to install the following components:

• Java 6 JDK Update 26
• Eclipse IDE for Java EE Developers 3.6.2 (Helios)
• Maven 3.0.3
• Glassfish 3.1

I suggest that you create a folder where you drop all the stuff we need to set-up the environment. My Folder is C:\jee6. I will call that <dev_home> when I refer to it.

Note: In one of my recent posts I explained how to set-up a Spring environment. This process is very simmilar, therefore I will only explain deviations in this Java EE set-up.

In this tutorial we will create a little demo project. The sample application uses JSF 2.0, CDI 1.0, EJB 3.1 and JPA 2.0 (persistence unit included). The demo can be used to start development of your own enterprise project.
