Setting up Java EE with Eclipse is pretty simple. Following are the steps:

1. Download Java EE Development Kit with JDK from Oracle. Choose a version that includes the GlassFish server.
2. Double-click and install. Assuming that you installed at c:\glassfish3.
3. Download Eclipse IDE for Java EE Developers from eclipse.org
4. Unzip to c:\
5. Open command prompt by clicking of the start icon and typing cmd in the search field. Press enter.
6. Type cd c:\eclipse
7. By default, eclipse only looks for JRE within its folders, so you need to specify the location on your JRE. To do this, type
   eclipse -vm c:\glassfish3\jdk\jre\bin\bin\javaw.exe
8. Obviously, you would not want to run this long command every time. So you need to change eclipse.ini settings. Open c:\eclipse.ini with a non-formatting editor like notepad.
   Add the following just above lines above --vmargs
   -vm
   c:\glassfish3\jdk\jre\bin\javaw.exe
   and save the changes.
9. Your eclipse.ini should look like the following:
   -startup
   plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
   --launcher.library
   plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.100.v20110502
   -product
   org.eclipse.epp.package.jee.product
   --launcher.defaultAction
   openFile
   --launcher.XXMaxPermSize
   256M
   -showsplash
   org.eclipse.platform
   --launcher.XXMaxPermSize
   256m
   --launcher.defaultAction
   openFile
   -vm
   c:\glassfish3\jdk\jre\bin\javaw.exe
   -vmargs
   -Dosgi.requiredJavaVersion=1.5
   -Xms40m
   -Xmx512m
10. double-click on the eclipse.exe icon to start eclipse. You might also want to add a shortcut to the desktop.
