Checking the level of Java

This is part of the larger task of customizing your z/OS environment.

To check your version of Java, enter java -version from an OMVS window. You will get a response similar to the following:
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0)
Classic VM (build 1.4.0, J2RE 1.4.0 IBM z/OS Persistent Reusable VM build cm1401
-20021127 (JIT enabled: jitc))
This indicates that the level of Java is 1.4.0, which is the minimum required level for this platform, as it is the lowest level that supports XPLink.
