The development kit for Java Enterprise Edition (formally known as J2EE Software Development Kit, or SDK) is a bundle containing a comprehensive collection of libraries and utilities needed to develop Java applications, applets and servlets. Sun Microsystems (acquired by Oracle) has ported the kit to all major architectures and operating systems, including Linux. You can install the J2EE SDK on a Linux computer.
Log in to the computer as user "root."
Launch a Web browser and navigate to the Oracle download page for the SDK. Accept the license, then click on the "Java Platform, Enterprise Edition 6 SDK Update 2 (with JDK 6 U25)" download link for your version of Linux -- the options are 32 or 64 bits. Wait until the download completes.
Launch a command shell by clicking on the "Terminal" icon on the graphical desktop. Type the following commands into the shell:
chmod +x "java_ee_sdk.sh"
Replace "~/Downloads" with the path to the directory where the SDK installer downloaded. Replace "java_ee_sdk.sh" with the file name of the downloaded SDK installer. Press "Enter" after each line. After a short delay, the shell will prompt you for the next command. At that point, the J2EE SDK will have been completely installed on the Linux computer.
