Using EJB Technology Best Practices
- Define best practices and state the benefits of using EJB technology best practices
- Select and apply known patterns to Java EE application design
- Incorporate effective exception handling into your Java EE application design
I guess that they are not talking about the old J2EE design patterns since many of them are useless since the Java EE 6 technology enhancements.
Do you have any idea of which patterns the current certification refers to?
