Recomended Weekly Link’s (from 17.10.2006)

This is my first weekly links issue. In its I will publicate articals interesting by me.

  • Stiff asks, great programmers answer

    With the help of public accessible e-mail adresses I asked 10 questions to a bunch of programmers that I consider very interesting people and I respect them for variuos things they created… But despite of this, I learn a lot of interesting stuff, so it was definietly a valuable experience.

  • Yes, we still need Transfer Objects with EJB3 JPA

    When we started our first project with the Java Persistence API (JPA) and EJB3, we made some decisions about the design… One of the decisions was to get rid of Data Transfer Objects. We took this decision because we firmly believed that the new annotated POJOs could be used a Transfer Objects between the different layers of our architecture. But it was not a good decision. Our database model was mapped to our entity model, and about 60-something classes aroused. I don’t think this is a complex model, but we can say it was ‘complex enough’. We found out very soon that the JPA POJOs were not good when they played the role of DTOs.
