The Geronimo Eclipse Plugin (GEP) requires the following prerequisite software (all of which is platform specific):

• Sun JDK 56.0 (J2SE 56.0)
• Eclipse IDE for Java EE Developers

Sun JDK 56.0 can be downloaded from Sun's J2SE 5.0 Downloads site. The Eclipse IDE for Java EE Developers can be downloaded in from the Eclipse Downloads site. Download and extract the Eclipse IDE for Java EE Developers archives to a directory of your choice (for example, C:\eclipse). The archive will be extracted to a directory named eclipse under the directory you specified (for example, C:\eclipse\eclipse), referred to as <ECLIPSE_HOME> from now on. Make sure that the JDK in the PATH is Sun JDK 56.0. Launch Eclipse by running <ECLIPSE_HOME>/eclipse.

The Geronimo server can be installed using the Geronimo Eclipse Plugin, or optionally you may install the manually. To install it manually, download the Geronimo 2.1.1 2 server from http://geronimo.apache.org/downloads.html and extract the archive to a directory of your choice (for e.g. C:\g). The archive will be extracted to a directory geronimo-tomcat6-javaee5-2.1.12 (for e.g. C:\g\geronimo-tomcat6-javaee5-2.1.12) or geronimo-jetty6-javaee5-2.1.12 depending on whether you downloaded Geronimo 2.1.1 2 distribution with Tomcat or Jetty as the web container. We will refer to this directory as <geronimo<GERONIMO_home>HOME> from now on.
