guys, I went thro the forum and got confused about how to prepare for the patterns.

I understand that familiarity with GoF patterns is mandatory.

DO I need to read J2EE patterns for part I?
If yes will "EJBDesignPatterns" from theserverside.com be enough?

Thanks a lot,
Varnika

u can check the design patterns on this link
http://java.sun.com/blueprints/corej2eepatterns/Patterns/

also u have to know GoF patterns thoroughly b'coz the questions are of the form -scenario described..u have to suggest the design pattern to be used.

i guess the ejb design patterns on serverside.com did not help me much for the part 1 of SCEA.

According to a SCEA book (Allen & Bambara) knowledge of J2EE patterns is not required for the part 1.

I'd take that statement with a pinch of salt. Granted, you don't have to know every J2EE pattern, but you are required to have a good understanding of GOF patterns and how J2EE platform architecture implements some of them. SCEA objectives published by Sun for Part I has the following section and it is pretty clear -


DESIGN PATTERNS:
� Identify the most appropriate design pattern for a given scenario
� Identify the benefits of using design patterns
� State the name of a Gamma et al. design pattern given the UML diagram and/or a brief description of the
pattern's functionality
� Identify benefits of a specified Gamma et al. design pattern
� Identify the Gamma et al. design pattern associated with a specified J2EE technology feature

Ajith,

I agree, you should know what a session facade is. But in my case the detailed questions with class diagrams etc. were about GOF patterns.
