EJB

Testing Non-Ruby Applications with Cucumber


Categories: | | | | |

Yesterday we got Cucumber working to test an older J2EE application that uses EJB 2.1 for its persistence layer. This application because of the J2EE EJB 2.1 beans has been very hard to near impossible to test in the past. I've been hearing about Cucumber for a while and we decided it was time to take a deeper look.

We plan on adding new features to this application using Rails, and over time porting the existing functionality to Rails. So, having a test suite written in Ruby that can test the application regardless of the underlying implementation was necessary. Cucumber with Webrat to the rescue. The general outline below will work with web applications written in any language. All of the interaction with the application happens at the HTTP protocol level.

Kicking the JBoss Habit: JBoss, JPA and Spring? Or Spring and JPA?

Hi, my name's Mark and I'm a JBoss user.

Ok now everyone.... "Hi Mark."

I have been a JBoss user for many many years. It all started with the seductive siren of Enterprise Java Beans. I still have a deployed application running on 2.4.3, or something like that. (Behind a firewall, thank heavens.) Well, today I took a few more solid steps toward kicking the JBoss habit.

If you've followed this blog you'll remember that I'm working on an ERP application for a client, Quadran. Yesterday I fought with query issues and JSP reloads for hours. With JBoss it's compile, package, re-deploy, wait. Change a few characters, compile, package, re-deploy and wait! It finally got to me.

JBoss 4, EJB 3 Entities (JPA), and Spring

Over the last week or so I have been working on getting JBoss, JPA and Spring working together. When I wrote my previous entry I thought I had everything working. Well, up to that point I had not tried to save a record to the database. When I tried to do that nothing happened. This lead to a long debugging process that felt more like a hopeless goose chase at times. With the help of Costin Leau on the Spring forum I finally got it working, but it was quite the trial. Not many people have attempted to get this combination working. One of the things that complicated my setup is that my data access objects are a descendant of the JpaDaoSupport class provided in the Spring framework.

Frameworks, API's, Interfaces.... Oh My! Defining a Foundation

One of the most important issues when starting a new project is the question of what tools, frameworks, and libraries are you going to use. In the past when starting a new project I take some time and survey the lay of the land. Well.. it's day one and I have been closely surveying the lay of the land.

It has been my intention that I would be using EJB 3.0 for this project, at least for the persistence layer. I have been looking at it for some time. I still feel comfortable with that decision. I've looked at Hibernate, which was the other possibility, but I think that EJB 3.0 will do for us.
