Subject: How to retrieve current default Java version programatically

Is there a way to programmatically (CL or RPG) to retrieve
the current default version of JAVA that is set.

I need to conditionally execute CL code based on the current
default version of JAVA
(The Java Version that will run if I were to execute
RUNJAVA)
I know I can retrieve the version(s) of JAVA that are
installed, but I need the current default version.
The version that is displayed by running JAVA *VERSION

Example
If CurVerJava < "1.5"
Do A
Else
Do B
Enddo


Thanks

John
