How To Tackle JavaEE - DevCrowd Keynote

How to structure a JavaEE application? How to organize your code? What are the essential ingredients of a maintainable JavaEE application? How to be productive with JavaEE?

I discussed such questions during the DevCrowd keynote:

Warning: I used slides in the first part of the keynote :-).

Hi, Adam

Could you compare Java EE with OSGi, as platforms for creating maintainable applications, having in mind OSGi Enterprise specification from one side, and usage of OSGi within many of Java EE containers, like Websphere and Jboss AS.

Do we have really important differences between this platforms?

Hi Adam,

Really nice presentation! I do not personally agree with everything but it does make a lot of sense.

One suggestion though, instead of showing mockito with @InjectMock, why you do not use the Arquillian framework and create first class citizen integration test that supports all the Java EE features?
You could also then show how to create a mock using CDI standard.

Again, keep up the good work,

Hi Adam,
good keynote, thx. I read your book and this is good compilation behind the idea of ECB design.

I have one question though.. You told that war file is enough. I'm using maven modules for better reusing. When I'm using only war file I end up with copying code from one project to other one and I don't see any point to do this -> error prone and super slow..

So here is the question: You start always developing from scratch or you have some kind of abstract components? -> overengineering

I think one reason was to much overhead. There was no point to introduce arquillian for such simple test.
