As I promised here this is the last part about using Maven2 to build, test and deploy an EJB3 application to JBoss5. In part 2 I showed how you can build and deploy your EJB3 application in JBoss. In this step I want to show you how you can (unit)test your EJB3 module before you deploy it to JBoss. In part 2 we had to deploy the bean first, before we could test it, but that is not the most optimal way. It would be nicer if the code is tested before it is deployed to the JBoss server. To do this, I make use of OpenEJB. This is a lightweight container that is very easy to use with Maven. Another advantage of this approach is that the EJB component is tested/used in two different EJB containers and reduces the possiblity that container-specific code is used in the application.

As I stated here I see three levels of using Maven2 to build and deploy your EJB3 application with JBoss5 as application server. The minimal use of Maven I have described here, in this post I will extend the role of Maven so you can use it for the deployment of the JEE application too. I will also show how to create a client class in Netbeans to test your deployment. To show this I will extend the example I used in the previous post.

Although I am pretty familair with EJB3 I decided to get prepared for my next certificate SCBCD by going through the book ‘Enterprise JavaBeans 3.0‘ by Burke and Monson-Haefel. A good thing about the book is that they added a ‘workbook’ in which exercises and coding examples are described. However, there is also a ‘disadvantage’ and that is that they use Ant to do the building, deploying and running of the code. And they use JBoss4.0 as an application server, which was the logical choice when the book came out, I guess, but is outdated nowadays. So I decided to rewrite the example a little as an exercise by making use of Maven2 for the building and deploying and do this on JBoss5.0.1 that has been released a few weeks ago.

Currently I am looking into the possiblities Mule has to offer for our project. One of the things that must be done is to transform a message on our (Tibco) queue to a JAXB object so we can use the object as parameter in our call to an EJB3 bean. How to call a EJB3 bean from Mule I have explained here. In this post I want to show how we setup our JAXB transformer. This transformer isn’t standard available in Mule but, as you will see, it is pretty easy to create your own transformer.

I have blogged before about how to generate JAXB binding classes based on your WSDL file, this time I wanted to generate JAXB classes based on just XSD files. Although I expected this to be simple, it took me quite some time to get it right, so I decided to give this item its own post :-)

Like I promised here I will show my project setup in which I test my EJB3 beans with OpenEJB. Although there are a lot of examples provided with OpenEJB I ran into some minor issues that I will explain here. I assume the Maven2 basics are known so I won’t go into much detail about that.

This is my stack:

• JDK1.5
• Maven2
• EJB3 project
• Glassfish EJB Container

I am setting up a new JEE project. In this project we will use EJB3 as framework for the business layer. And of course we are using Maven to build, test and deploy the application. One important issue I have to deal with is how to (unit)test this business layer.
I had a look at the following options:

• Use EJB3Unit
• Make my own base test classes
• Use OpenEJB container

A year ago I posted how you could create a EJB3 webservice and deploy it on JBoss with Maven. Currently I am doing a similar thing at my project, but this time I deploy it to Glassfish. The creation of the web serive is similar but for the deployment you will need another plugin (if you want Maven to deploy the webservice, of course).

In this blog I’ll show you how you can create a WebService of your EJB3 objects by using anotations. I will also show you how to build and deploy the package with Maven2. Let’s start with the initial situation.
I have installed JBoss 4.2.1 and Maven2. In my settings.xml of Maven2 I have set a property pointing to my JBoss installation and I have defined a JBoss/Maven2 repository.

Do you recognize this: Although you are using a tool to develop your applications for some time, you are suddenly surprised by a certain error message you haven’t seen before? And you didn’t do anything different compared to the last time you used it.
Well, my experience is that in 100 times out of a 100, you did do something different. My last time in this situation was when I wanted to use a Java 1.5 enum type as a field in my EJB3 entity bean. I had done this before and at first sight everything looked well. Here was what I did:
