Where can I find study material on -
"Service Locator pattern". Not able to find it in "Thinking in Patterns by Bruce Eckel". Is there any different name used for this pattern?

Is "Tranfer Object" same as "Value Object" or are these different.

I have never used or worked on Patterns till now.
What is the best way to start for a beginner?

rashmi,

Welcome to JavaRanch!

We ain't got many rules 'round these parts, but we do got one. Please change your display name to comply with The JavaRanch Naming Policy.

We request display names to follow the pattern FIRST_NAME + SPACE + LAST_NAME.

Thanks Pardner! Hope to see you 'round the Ranch!

I have studied the Design Patterns specified in objectives from the link:
http://java.sun.com/blueprints/corej2eepatterns/Patterns/index.html

Is this sufficient for 1.4 exam. Where can I find some practice questions for the exam?
