If you prefer to use your existing Java Runtime Environment (JRE), or if you are installing Reflection for the Web on Solaris, use the nojre installation package. The JRE must be Java 1.8 or higher.
To use any of the -unix-nojre- installation packages, confirm that a JRE appropriate for your platform is already installed.
For example, to install Reflection for the Web on a z/Linux machine, download the JRE from this location: http://www.ibm.com/developerworks/java/jdk/linux/download.html
Expand the package you want to use, such as
rwebenterprise-prod-unix-nojre-manual.tar.gz
