Updating the JRE/JDK Used by the Installers

The installation of a Development Client places two JRE’s under the installation directory. One is provided by OUI itself and is used only by OUI during deinstallation. The second is in the system directory and is used by EnterpriseOne at runtime.

If you need to replace the JRE used at runtime (for example, to avoid security vulnerabilities), replace the one on the Deployment Server under the system directory (such as, \\<deployment server name>\<release>\system\jre) and build and deploy a package containing that foundation/system.

If you need to replace the JRE used during deinstallation, follow these steps after installing a package onto the Development Client:

  1. Drill down to <E1_install_dir>\jre\1.8.0
  2. Copy the contents of the JRE you want into that 1.8.0 directory. That directory should contain, among other things, bin and lib subdirectories.
Important: It is very important that you do not rename the 1.8.0 directory and that the directory contains the new JRE files and subdirectories.
Note: When a package is installed, that jre\1.8.0 directory will be replaced. You will need to replace the JRE after each package is installed.
