Selecting the Appropriate JRE

The Message Queue 4. 1 Installer JDK Selection Screen allows you to select existing JDK/JRE's on the system for use by Message Queue. Unfortunately, the list shown also includes the JRE used to run the installer application. This JRE is part of the installer bundle and is not really installed on the system. (Bug 6585911)

The JRE used by the installer is recognizable by its path, which should be within the unzipped installer directory and should include the subdirectory mq4_1–installer. For example:

some_directory/mq4_1–installer/usr/jdk/instances/jdk1.5.0/jre

Do not select this JRE for use by Message Queue. Instead, select another JDK on the system. If one does not exist, take the action appropriate for your platform.

• Solaris or Linux: Select “Install and use the default JDK”.

• Windows: Download and install a JDK before running the Message Queue 4.1 installer.
