Installing EclipseLink for Java SE and Jakarta EE Development

Use the following procedures to install EclipseLink for Java SE and EE development. Before you proceed with the install, it is recommended that you back up any existing project data.

1. Set the following system environment variables before installing EclipseLink:

   • JAVA_HOME - Set JAVA_HOME to where you installed your Java SDK home directory. For example:

     • Windows example: JAVA_HOME = C:\JDK

     • UNIX example: JAVA_HOME = ...:/usr/java/jdk

   • PATH - Set PATH to include JDK/bin directory. For example:

     • Windows example: PATH = C:\JDK\bin

     • UNIX example: PATH = ...:/usr/java/jdk/bin

2. Download the EclipseLink install archive zip file, eclipse-ver_no.zip, from the EclipseLink downloads page at http://www.eclipse.org/eclipselink/downloads/

3. Unzip the downloaded file in the desired installation directory. When you unzip the file, you will find an eclipselink subdirectory, containing multiple subdirectories. This directory is your new ECLIPSELINK_HOME directory. For example:

   • Windows example: ECLIPSELINK_HOME = <INSTALL_DIR>/eclipselink

   • UNIX example: ECLIPSELINK_HOME = ...:/usr/el/INSTALL_DIR/eclipselink
