Some help packages might be built without the required Java™ JRE. Building packages without the required Java JRE saves on package size and assumes that most systems already have a
JRE installed.
If a JRE is not installed or the
JAVA_HOME environment variable is not set, you
might see an error message when you start the local IBM®
Knowledge Center. For example:
Error: No JAVA_HOME defined
Resolution
Ensure that a JRE is installed and the JAVA_HOME variable is set. For
example:
Variable: JAVA_HOME
Value: C:\Program Files\IBM\JAVA71\jre
