EJB - Environment Setup


Advertisements


EJB is a framework for Java, so the very first requirement is to have a Java Development Kit (JDK) installed in your machine.

System Requirement

JDK 1.5 or above.
Memory no minimum requirement.
Disk Space no minimum requirement.
Operating System no minimum requirement.

Step 1 - Verify Java Installation in Your System

Now open console and execute the following java command.

OS Task Command
Windows Open Command Console c:\> java -version
Linux Open Command Terminal $ java -version
Mac Open Terminal machine:~ joseph$ java -version

Let's verify the output for all the operating systems −

OS Output
Windows

java version "1.6.0_21"

Java(TM) SE Runtime Environment (build 1.6.0_21-b11)

Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)

Linux

java version "1.6.0_21"

Java(TM) SE Runtime Environment (build 1.6.0_21-b11)

Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)

Mac

java version "1.6.0_21"

Java(TM) SE Runtime Environment (build 1.6.0_21-b11)

Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)

If you do not have Java installed, install the Java Software Development Kit (SDK) from https://www.oracle.com/technetwork/java/javase/downloads/index.html. We are assuming that Java 1.6.0_21 as installed version for this tutorial.

Step 2 – Set JAVA Environment

Set the JAVA_HOME environment variable to point the base directory location where Java is installed on your system. For example,

OS Output
Windows Set the environment variable JAVA_HOME to C:\Program Files\Java\jdk1.6.0_21
Linux export JAVA_HOME=/usr/local/java-current
Mac export JAVA_HOME=/Library/Java/Home

Append Java compiler location to System Path.

OS Output
Windows Append the string ;C:\Program Files\Java\jdk1.6.0_21\bin to the end of the system variable, Path.
Linux export PATH=$PATH:$JAVA_HOME/bin/
Mac not required

Verify Java Installation using java -version command explained above.

Step 3 – Download and Install NetBeans IDE

Download the latest version of NetBeans IDE from https://netbeans.org/downloads/index.html. At the time of writing this tutorial, I downloaded Netbeans 7.3 which comes bundled with JDK 1.7 using the following link https://www.oracle.com/technetwork/java/javase/downloads/index.html

OS Installer name
Windows Netbeans 7.3
Linux Netbeans 7.3
Mac Netbeans 7.3

Step 4 – Setup JBoss Application Server

You can download the latest version of JBoss Server from https://www.jboss.org/jbossas/downloads/. Download the archive as per the platform. Extract the Jboss to any location on your machine.

OS File name
Windows jboss-5.1.0.GA-jdk6.zip
Linux jboss-5.1.0.GA-src.tar.gz
Mac jboss-5.1.0.GA-src.tar.gz

Step 5 - Configure JEE Plugins to Netbeans

Open Plugin window using Tools > Plugins. Open "Available Plugin" tab and select "Java EE Base" and "EJB and EAR" under "Java Web and EE" category. Click install button. Netbeans will download and install the respective plugins. Verify plugins installation using "Installed" tab (as shown in the image given below).

Installed plugins

Step 6 - Configure JBoss Server in Netbeans

Go to Services tab and right click on servers to add a new server.

Add Server

Add Server Instance wizard will open. Select JBoss and in next step enter the relevant details to configure server in netbeans.

Choose Server

Once everything is configured, you will see the following screen.

Installed servers

Step 7 - Install Database Server (PostGreSql)

Download latest version of PostGreSql database server from https://www.postgresql.org/download/. At the time of writing this tutorial, I downloaded PostGreSql 9.2

OS Installer name
Windows PostGreSql 9.2
Linux PostGreSql 9.2
Mac PostGreSql 9.2
