Flex - Environment Setup

Advertisements


This tutorial will guide you on how to prepare a development environment to start your work with Adobe Flex Framework. This tutorial will also teach you how to setup JDK and Adobe Flash Builder on your machine before you setup Flex Framework:

System Requirement

FLEX requires JDK 1.4 or higher so the very first requirement is to have JDK installed in your machine.

JDK1.4 or above.
Memoryno minimum requirement.
Disk Spaceno minimum requirement.
Operating Systemno minimum requirement.

Follow the given steps to setup your environment to start with Flex 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

Step 3 - Setup Adobe Flash Builder 4.5

All the examples in this tutorial have been written using Adobe Flash Builder 4.5 Profession IDE Trial Version. So I would suggest you should have latest version of Adobe Flash Builder installed on your machine based on your operating system.

To install Adobe Flash Builder IDE, download the latest Adobe Flash Builder binaries from http://www.adobe.com/in/products/flash-builder.html. Once you downloaded the installation, unpack the binary distribution into a convenient location. For example in C:\flash-builder on windows, or /usr/local/flash-builder on Linux/Unix and finally set PATH variable appropriately.

Flash Builder can be started by executing the following commands on windows machine, or you can simply double click on FlashBuilder.exe

 %C:\flash-builder\FlashBuilder.exe

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

$/usr/local/flash-builder/FlashBuilder

Adobe Flash Builder Trial Version can be used for 60 days. Just accept the terms and conditions and skip the initial registration steps and continue with the IDE. We're using the trial version for teaching purpose.

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

FlashBuilder Home page

Adobe Flash Builder comes pre-configured with FLEX SDKs. We're using FLEX SDK 4.5 in our examples which comes bundled with Adobe Flash Builder 4.5.

Step 4: 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
