Hi Folks,
I have a doubt,
are j2ee patterns are included in the questions, or GOF patterns are sufficient.
Also there was some discussion about ejb design patterns. Are they very differant from GOF patterns, if yes where we can find out some study material for that.
Regards,

No, J2EE patterns are not in the exam (even though J2ee patterns uses some GOF patterns).
I will advice to understand the concept of each pattern and which are the Java objects implementing them !!!
For instance :
Abstract factory ( DAO patterns, jspfactory...), Factory method (ejbhome create method), Proxy (ejbobject), Prototype (Cloneable interface) , Adapter (WindowsAdapter), Decorator (FilterInputStream), Iterator (Collection)...and so on.

I already mentioned in a different thread but :
Bridge, Flyweight, Interpreter, Memento, Template are not in the exam.
