{scrollbar}We will be using Eclipse Galileo and Sun JDK 6.0+ for the illustration. Geronimo Eclipse Plugin (GEP) can be installed using the following options:


This page describes how to install the current release of the GEP (GEP 3.0-M1).

For information about installing previous releases, see this page.

Note that v3.0-M1 Geronimo server adapter feature provides server adapters for the v1.1.x, v2.0.x, v2.1.x, v2.2 and v3.0-M1 Geronimo servers. The reason for supporting v1.1.x server is to make v1.1.x server adapter compatible with latest version of eclipse. But since Geronimo 1.1 did not officially support JDK 6, it's not recommended to use v1.1.x server adapter with JDK 6. See the requirement in GERONIMODEVTOOLS-578.

If you plan to upgrade GEP to the latest version, you have to uninstall the existing one from your Eclipse first. See Uninstalling GEP for more details.

Prerequisites Prereqs

Sun JDK 6.0 can be downloaded from Sun's J2SE 6.0 Downloads site. The Eclipse IDE for Java EE Developers can be downloaded from the Eclipse Downloads site. Download and extract the Eclipse IDE for Java EE Developers archives to a directory of your choice (for e.g. C:\eclipse). The archive will be extracted to a directory named eclipse under the directory you specified (for e.g. C:\eclipse\eclipse), referred to as <ECLIPSE_HOME> from now on. Make sure that the JDK in the PATH is Sun JDK 6.0. Launch Eclipse by running <ECLIPSE_HOME>/eclipse.

To install the Geronimo server, download the Geronimo 3.0-M1 server from 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-javaee5-3.0-M1 (for e.g. C:\g\geronimo-tomcat7-javaee5-3.0-M1) or geronimo-jetty7-javaee6-3.0-M1 depending on whether you downloaded Geronimo 3.0-M1 distribution with Tomcat or Jetty as the web container. We will refer to this directory as <GERONIMO_HOME> from now on.

Installing GEP using Eclipse update manager

(star) A video desktop demonstration of Installing the Apache Geronimo Eclipse Plugin with the Eclipse Update Manager is available.

  1. Once you have all the prerequisites installed. Launch Eclipse from <ECLIPSE_HOME>/eclipse. By default Eclipse will be launched with Java EE perspective.
  2. Select Help->Install New Softwares... from the menu.

  10. Once GEP is installed you will be prompted to restart. Select Yes.

Installing GEP within WTP

  1. Once you have all the #Prerequisites installed, launch Eclipse from <ECLIPSE_HOME>/eclipse.By default Eclipse will be launched with Java EE perspective.
  2. Select the Servers tab as shown in the figure and select New->Server.

From version 3.4, Eclipse adopted a new update manager called P2. The update manager can't uninstall plug-ins that isn't installed by P2. As a result, with this method, GEP can't be uninstalled by eclipse update manager in eclipse 3.4. See Bug245469 for details.

Uninstalling GEP UninstallGEP

GEP may be uninstalled in a similar manner in which it was installed.

Uninstall does not work well on Helios, especially for GEP. It will uninstall GEP, but then you can't reinstall it, as it doesn't really get uninstalled. The only way to reinstall GEP in Helios is to reinstall Helios itself! See Eclipse Bugzilla 244935 for details, and hopefully a fix soon!
