Confused about Patterns

[varnika Raman]

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.

you need to know only about DAO pattern from j2ee patterns and all GoF patterns for part1 exam

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.
