Srinija,
Welcome to Javaranch!

Have you seen Sun's J2EE core patterns page? In additon to being a good reference for the patterns, they include some of them into the Pet Store application.

you are appearing for SCWCD exam. which covers the web tier of J2EE. and you posted this question on EJB forum that is a business tier. first of all you should know that the exam you are going to take is a web tier exam, primarily JSP and Servlets.
