Padma,
Java EE is simply a renaming of J2EE. It is the latest version of J2EE (if Sun had kept the old naming convention, Java EE 5 would have been J2EE 1.5).
Since Java EE is nothing but the latest version of J2EE, it includes the latest versions of all technologies and APIs in J2EE, including
Servlets, JSPs, EJBs, etc. Java EE 5 also includes new technologies that were not part of older versions of J2EE, including
JSF (Java Server Faces) and JPA (Java Persistence API).
If you are comfortable with the Java language
you should have no problem learning Java EE. The book assumes no previous knowledge of Java EE or J2EE, but it does assume Java knowledge.
