Users whose platforms have Java 1.4 or an earlier version installed as the default JVM must unset environment variable JRE_HOME to resolve a Java version problem.
If your platform has Java 1.4 or an earlier version installed as the default JVM, the Ops Console may fail to start.
To resolve the version problem, unset JRE_HOME if it exists in the environment. If JRE_HOME does not exist in environment (in other words, is unset) and the install works correctly, RAP will use the Java 1.5 that comes with the installer to run everything.
The environment variable $JRE_HOME should point to the $RAP/shared/jre15 directory under the install image.
