JSF - Environment Setup
JSF - Environment Setup
This chapter will guide you on how to prepare a development environment to start your work with JSF Framework. You will learn how to setup JDK, Ecppse, Maven, and Tomcat on your machine before you set up JSF Framework.
System Requirement
JSF requires JDK 1.5 or higher so the very first requirement is to have JDK installed on your machine.
| JDK | 1.5 or above |
| Memory | No minimum requirement |
| Disk Space | No minimum requirement |
| Operating System | No minimum requirement |
Environment Setup for JSF Apppcation Development
Follow the given steps to setup your environment to start with JSF apppcation development.
Step 1: Verify Java installation on your machine
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 | Generated Output |
|---|---|
| Windows | java version "1.6.0_21" Java(TM) SE Runtime Environment (build 1.6.0_21-b07) Java HotSpot(TM) Cpent 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) Cpent 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: Set Up 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 − . You will find instructions for instalpng 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 −
| OS | Output |
|---|---|
| Windows | Set the environment variable JAVA_HOME to C:Program FilesJavajdk1.6.0_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 ;%JAVA_HOME%in to the end of the system variable, Path. |
| Linux | Export PATH=$PATH:$JAVA_HOME/bin/ |
| Mac | Not required |
Alternatively, if you use an Integrated Development Environment (IDE) pke Borland JBuilder, Ecppse, IntelpJ IDEA, or Sun ONE Studio, compile and run a simple program to confirm that the IDE knows where you installed Java. Otherwise, carry out a proper setup according to the given document of the IDE.
Step 3: Set Up Ecppse IDE
All the examples in this tutorial have been written using Ecppse IDE. Hence, we suggest you should have the latest version of Ecppse installed on your machine based on your operating system.
To install Ecppse IDE, download the latest Ecppse binaries with WTP support from . Once you download the installation, unpack the binary distribution into a convenient location. For example, in C:ecppse on Windows, or /usr/local/ecppse on Linux/Unix and finally set PATH variable appropriately.
Ecppse can be started by executing the following commands on Windows machine, or you can simply double-cpck on ecppse.exe
%C:ecppseecppse.exe
Ecppse can be started by executing the following commands on Unix (Solaris, Linux, etc.) machine −
$/usr/local/ecppse/ecppse
After a successful startup, if everything is fine then it will display the following result.
*Note − Install m2ecppse plugin to ecppse using the following ecppse software update site
m2ecppse Plugin - .
This plugin enables the developers to run maven commands within ecppse with embedded/external maven installation.
Step 4: Download Maven archive
Download Maven 2.2.1 from
| OS | Archive name |
|---|---|
| Windows | apache-maven-2.0.11-bin.zip |
| Linux | apache-maven-2.0.11-bin.tar.gz |
| Mac | apache-maven-2.0.11-bin.tar.gz |
Step 5: Extract the Maven archive
Extract the archive to the directory you wish to install Maven 2.2.1. The subdirectory apache-maven-2.2.1 will be created from the archive.
| OS | Location (can be different based on your installation) |
|---|---|
| Windows | C:Program FilesApache Software Foundationapache-maven-2.2.1 |
| Linux | /usr/local/apache-maven |
| Mac | /usr/local/apache-maven |
Step 6: Set Maven environment variables
Add M2_HOME, M2, MAVEN_OPTS to environment variables.
| OS | Output |
|---|---|
| Windows | Set the environment variables using system properties. M2_HOME=C:Program FilesApache Software Foundationapachemaven-2.2.1 M2=%M2_HOME%in MAVEN_OPTS=-Xms256m -Xmx512m |
| Linux | Open command terminal and set environment variables. export M2_HOME=/usr/local/apache-maven/apache-maven-2.2.1 export M2=%M2_HOME%in export MAVEN_OPTS=-Xms256m -Xmx512m |
| Mac | Open command terminal and set environment variables. export M2_HOME=/usr/local/apache-maven/apache-maven-2.2.1 export M2=%M2_HOME%in export MAVEN_OPTS=-Xms256m -Xmx512m |
Step 7: Add Maven bin directory location to system path
Now append M2 variable to System Path.
| OS | Output |
|---|---|
| Windows | Append the string ;%M2% to the end of the system variable, Path. |
| Linux | export PATH=$M2:$PATH |
| Mac | export PATH=$M2:$PATH |
Step 8: Verify Maven installation.
Open console, execute the following mvn command.
| OS | Task | Command |
|---|---|---|
| Windows | Open Command Console | c:> mvn --version |
| Linux | Open Command Terminal | $ mvn --version |
| Mac | Open Terminal | machine:~ joseph$ mvn --version |
Finally, verify the output of the above commands, which should be as shown in the following table.
| OS | Output |
|---|---|
| Windows | Apache Maven 2.2.1 (r801777; 2009-08-07 00:46:01+0530) Java version: 1.6.0_21 Java home: C:Program FilesJavajdk1.6.0_21jre |
| Linux | Apache Maven 2.2.1 (r801777; 2009-08-07 00:46:01+0530) Java version: 1.6.0_21 Java home: C:Program FilesJavajdk1.6.0_21jre |
| Mac | Apache Maven 2.2.1 (r801777; 2009-08-07 00:46:01+0530) Java version: 1.6.0_21 Java home: C:Program FilesJavajdk1.6.0_21jre |
Step 9: Set Up Apache Tomcat
You can download the latest version of Tomcat from . Once you download 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-cpck on startup.bat
%CATALINA_HOME%instartup.bat or C:apache-tomcat-6.0.33instartup.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 apppcations included with Tomcat will be available by visiting http://localhost:8080/. If everything is fine, then it will display the following result.
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%inshutdown or C:apache-tomcat-5.5.29inshutdown
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.shAdvertisements
