The whole last week I was migrating my current project from the JBoss AS 6 M2 to the JBoss AS 6 CR1. First of all I had been thinking it should be easy, just switch few things, use other Java packages and so on. Niether I had been expecting some problems nor it will take a week. So I’ve just started my migration “project” – yep, you should always treat it that way, it isn’t just renaming packages or tweaking some configuration files. It’s a huge project that either can take a hour or a week. So be prepared!

To move to the JBoss CR1 I had to also switch to latest versions of our internal libraries, commonly called SML Commons. The main problem was with the CDI Extension package, which base on WELD. During switching the version I discovered some problems during an application deployment. First of all Bean Manager was missing in JNDI context. Googling and looking through existing solution didn’t help. I had to prepare a demo application and try to register an issue with JBoss’ JIRA. The problem was, that my demo application was working just fine with the JBoss CR1. Just Adam was able to break it – the trick was to include in EAR package another module as a Java JAR archive with CDI enabled beans. Then the application blown up!Sandy Wexler film trailer

After few hours we got answer to the problem –  add additional beans.xml file to WAR archive!

So I thought the rest should be easy, but wasn’t 😛

The next problem was with the application’s tests. All the tests that were base on Arquillian started yielding – wrong dependency in Maven pom, I had to remove few of them, cut out some unused profile and everything went smoothly.

So, the next problem was with Selenium and it looked strange as the whole JVM blown up with irritating “red zone” message. And till now I don’t know what it was, maybe just wrong configuration or missing dependency. And during solving that problem I discovered a really interesting CDI behaviour. When you defining a bean with @Produces annotation you have access to the InjectionPoint object. It provides many different information about where your bean will be injected.

But there is a slight diference how InjectionPoint.getBean() is working. If your @Produces annotated bean will be used / injected in already CDI managed bean, getBean() will return that bean. But in other way it will return null 😛

Finally, I gave up 🙁 After passing all that problems, another one hit me directly in the face and I haven’t had enough energy to solved it. I shelved all my changes with IntelliJ IDEA and returned to normal coding work, ufff…. 🙂

And just to change my attitude, today’s morning I got monthly newsletter from TED and I want to share with you that brilliant talk about why bosses and meetings are boilerplate at work, enjoy!
