JSF - Environment Setup

Advertisements


This tutorial will guide you on how to prepare a development environment to start your work with JSF Framework. This tutorial will also teach you how to setup JDK, Eclipse, Maven, and Tomcat on your machine before you setup JSF Framework:

System Requirement

JSF requires JDK 1.5 or higher so the very first requirement is to have JDK installed in your machine.

JDK1.5 or above.
Memoryno minimum requirement.
Disk Spaceno minimum requirement.
Operating Systemno minimum requirement.

Follow the given steps to setup your environment to start with JSF application development.

Step 1 - Verify Java installation on your machine

Now open console and execute the following java command.

OSTaskCommand
WindowsOpen Command Consolec:\> java -version
LinuxOpen Command Terminal$ java -version
MacOpen Terminalmachine:~ joseph$ java -version

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

OSGenerated Output
Windows java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b07)
Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode, sharing)
Linux java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b07)
Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode, sharing)
Mac java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b07)
Java HotSpot(TM)64-Bit Server VM (build 17.0-b17, mixed mode, sharing)

Step 2 - Setup Java Development Kit (JDK):

If you do not have Java installed then you can install the Java Software Development Kit (SDK) from Oracle's Java site: Java SE Downloads. You will find instructions for installing JDK in downloaded files, follow the given instructions to install and configure the setup. Finally set PATH and JAVA_HOME environment variables to refer to the directory that contains java and javac, typically java_install_dir/bin and java_install_dir respectively.

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

OSOutput
WindowsSet the environment variable JAVA_HOME to C:\Program Files\Java\jdk1.6.0_21
Linuxexport JAVA_HOME=/usr/local/java-current
Macexport JAVA_HOME=/Library/Java/Home

Append Java compiler location to System Path.

OSOutput
WindowsAppend the string ;%JAVA_HOME%\bin to the end of the system variable, Path.
Linuxexport PATH=$PATH:$JAVA_HOME/bin/
Macnot required

Alternatively, if you use an Integrated Development Environment (IDE) like Borland JBuilder, Eclipse, IntelliJ IDEA, or Sun ONE Studio, compile and run a simple program to confirm that the IDE knows where you installed Java, otherwise do proper setup as given document of the IDE.

Step 3 - Setup Eclipse IDE

All the examples in this tutorial have been written using Eclipse IDE. So I would suggest you should have latest version of Eclipse installed on your machine based on your operating system.

To install Eclipse IDE, download the latest Eclipse binaries with WTP support from http://www.eclipse.org/downloads/. Once you downloaded the installation, unpack the binary distribution into a convenient location. For example in C:\eclipse on windows, or /usr/local/eclipse on Linux/Unix and finally set PATH variable appropriately.

Eclipse can be started by executing the following commands on windows machine, or you can simply double click on eclipse.exe

 %C:\eclipse\eclipse.exe

Eclipse can be started by executing the following commands on Unix (Solaris, Linux, etc.) machine:

$/usr/local/eclipse/eclipse

After a successful startup, if everything is fine then it should display following result:

Eclipse Home page

*Note: Install m2eclipse plugin to eclipse using following eclipse software update site

m2eclipse Plugin - http://m2eclipse.sonatype.org/update/.

This plugin enables developers to run maven commands within eclipse with embedded/external maven installation.

Step 4: Download Maven archive

Download Maven 2.2.1 from http://maven.apache.org/download.html

OSArchive name
Windowsapache-maven-2.0.11-bin.zip
Linuxapache-maven-2.0.11-bin.tar.gz
Macapache-maven-2.0.11-bin.tar.gz

Step 5: Extract the Maven archive

Extract the archive, to the directory you wish to install Maven 2.2.1. The subdirectory apache-maven-2.2.1 will be created from the archive.

OSLocation (can be different based on your installation)
WindowsC:\Program Files\Apache Software Foundation\apache-maven-2.2.1
Linux /usr/local/apache-maven
Mac/usr/local/apache-maven

Step 6: Set Maven environment variables

Add M2_HOME, M2, MAVEN_OPTS to environment variables.

OSOutput
WindowsSet the environment variables using system properties.

M2_HOME=C:\Program Files\Apache Software Foundation\apache-maven-2.2.1

M2=%M2_HOME%\bin

MAVEN_OPTS=-Xms256m -Xmx512m

LinuxOpen command terminal and set environment variables.

export M2_HOME=/usr/local/apache-maven/apache-maven-2.2.1

export M2=%M2_HOME%\bin

export MAVEN_OPTS=-Xms256m -Xmx512m

MacOpen command terminal and set environment variables.

export M2_HOME=/usr/local/apache-maven/apache-maven-2.2.1

export M2=%M2_HOME%\bin

export MAVEN_OPTS=-Xms256m -Xmx512m

Step 7: Add Maven bin directory location to system path

Now append M2 variable to System Path

OSOutput
WindowsAppend the string ;%M2% to the end of the system variable, Path.
Linuxexport PATH=$M2:$PATH
Macexport PATH=$M2:$PATH

Step 8: Verify Maven installation

Now open console, execute the following mvn command.

OSTaskCommand
WindowsOpen Command Consolec:\> mvn --version
LinuxOpen Command Terminal$ mvn --version
MacOpen Terminalmachine:~ joseph$ mvn --version

Finally, verify the output of the above commands, which should be something as follows:

OSOutput
Windows Apache Maven 2.2.1 (r801777; 2009-08-07 00:46:01+0530)
Java version: 1.6.0_21
Java home: C:\Program Files\Java\jdk1.6.0_21\jre
Linux Apache Maven 2.2.1 (r801777; 2009-08-07 00:46:01+0530)
Java version: 1.6.0_21
Java home: C:\Program Files\Java\jdk1.6.0_21\jre
Mac Apache Maven 2.2.1 (r801777; 2009-08-07 00:46:01+0530)
Java version: 1.6.0_21
Java home: C:\Program Files\Java\jdk1.6.0_21\jre

Step 9: Setup Apache Tomcat:

You can download the latest version of Tomcat from http://tomcat.apache.org/. Once you downloaded the installation, unpack the binary distribution into a convenient location. For example in C:\apache-tomcat-6.0.33 on windows, or /usr/local/apache-tomcat-6.0.33 on Linux/Unix and set CATALINA_HOME environment variable pointing to the installation locations.

Tomcat can be started by executing the following commands on windows machine, or you can simply double click on startup.bat

 %CATALINA_HOME%\bin\startup.bat
 
 or
 
 C:\apache-tomcat-6.0.33\bin\startup.bat

Tomcat can be started by executing the following commands on Unix (Solaris, Linux, etc.) machine:

$CATALINA_HOME/bin/startup.sh
 
or
 
/usr/local/apache-tomcat-6.0.33/bin/startup.sh

After a successful startup, the default web applications included with Tomcat will be available by visiting http://localhost:8080/. If everything is fine then it should display following result:

Tomcat Home page

Further information about configuring and running Tomcat can be found in the documentation included here, as well as on the Tomcat web site: http://tomcat.apache.org

Tomcat can be stopped by executing the following commands on windows machine:

%CATALINA_HOME%\bin\shutdown
 
or
 
C:\apache-tomcat-5.5.29\bin\shutdown

Tomcat can be stopped by executing the following commands on Unix (Solaris, Linux, etc.) machine:

$CATALINA_HOME/bin/shutdown.sh
 
or
 
/usr/local/apache-tomcat-5.5.29/bin/shutdown.sh
