Chapter 1: Getting started with Java EE
Section 1.1: What is Java EE?
Java EE stands for Java Enterprise Edition. Java EE extends the Java SE (which stands for Java Standard Edition). Java
EE is a set of technologies and related specifications that are oriented towards the development of large-scale
enterprise applications. Java EE is developed in a community driven process. So far the following versions of Java EE
have been released:
J2EE 1.2 (December12, 1999)
J2EE 1.3 (September 24, 2001)
J2EE 1.4 (November 11, 2003)
Java EE 5 (May 11, 2006)
Java EE 6 (December 10, 2009)
Java EE 7 (April 5, 2013)
Java EE 8 (August 31, 2017)
A key concept of the Java EE is that every Java EE version is comprised by a set of specific technologies. These
technologies address specific JSRs (Java Specification Requests). In order for a programmer to use these
technologies he needs to download an implementation of the Java EE technology specifications. The Java
Community provides a reference implementation for each technology but other Java EE compliant technologies are
developed and can also be used. The community provides a set of tests, namely the Java Compatibility Kit (JCK) that
can be used by the developers of a JSR implementation to check if it is compliant or not with the JSR. The following
table gives an overview of the technologies that comprise Java EE 7 and the related JSR that define the specs.

Section 1.2: Installation
First of all, you cannot "install" Java EE. Java EE consists of a number of specifications. You can install
implementations of those specifications however.
Depending on your needs, there are lots of possibilities. To install most (or all) of the specifications, you can choose
a Java EE 7 compatible Application Server. Depending on your needs, you can choose between application servers
that implement the web profile or application servers that implement the full profile. For a list of Java EE7
compatible application servers see
Java EE Compatibility.
Section 1.3: Installing Payara Server Full
Prerequisites
JDK 1.7 or later installed. You can find the Oracle JDK's
here.
Steps
Download
Payara Server Full.
Unzip the Payara Server at some location on your computer. We will use
C:\payara41
as INSTALL_DIR for
Windows users and
/payara41
for Linux/Mac users.
Starting / stopping Payara from the command prompt
Windows: Open a command prompt and execute the following command to start/stop Payara:
"C:\payara41\bin\asadmin"
start-domain
"C:\payara41\bin\asadmin"
stop-domain
Linux/Max: Open a terminal and execute the following command to start/stop Payara:
