What is J2EE , is it same of Java?

Answer 1

Some of the key features and services of J2EE:

> At the client tier, J2EE supports pure HTML, as well as Java applets or applications. It relies on Java Server Pages and servlet code to create HTML or other formatted data for the client.

> Enterprise JavaBeans (EJBs) provide another layer where the platform's logic is stored. An EJB server provides functions such as threading, concurrency, security and memory management. These services are transparent to the author.

> Java Database Connectivity (JDBC), which is the Java equivalent to ODBC, is the standard interface for Java databases.

> The Java servlet API enhances consistency for developers without requiring a graphical user interface.

Key difference:
Java is a programming language, which has been influenced by the C language. It derives much of its syntax from C and C++, however it has fewer low-level facilities than either.
J2EE is a computing platform that is based on the Java programming language. A computing platform allows the developed software to run.

Answer 2

That's the enterprise edition of Java (and currently it's just Java EE). Personally I can not give you much information, since I do not usually develop with Java, but I know that it defines a series of standards for the development of applications. Here you can see a little more of the Oracle specification.
