The Eclipse IDE for Java EE Developers is by far the most popular download in the Eclipse IDE family. Developers use it mainly for developing Java Web Applications, which are made up of primarily JSP, XML, HTML files and Java Servlets. Installing the Eclipse IDE for Java EE Developers can be done in a few simple steps.
Step 1: Go to www.eclipse.org and download the proper version of Eclipse for your operating system. I happen to be developing on a 64-bit Mac running Mac OS X Leopard, so I downloaded the Mac Cocoa 64-bit version.
Step 2: Unzip the downloaded *.tar.gz file (double-click it) and move the "eclipse" folder to the root of your hard drive. Eclipse is installed!
Step 3: In the /eclipse directory, you'll find a Eclipse.app file. Double clicking it will start Eclipse. I prefer to drag this file down to the Dock for easy access.
Step 4: Once Eclipse is started, you'll be greeted by the Eclipse welcome screen.
Step 5: Click on the Workbench icon in the upper right corner to get to the workbench. You'll be asked to choose a workspace. This is where all your Java EE projects will reside.
Piece of Cake!!
