RE: Setting the JVM version

["Rooney, Michael P" <michael.p.rooney@xxxxxxxxxxxxx>]

Barbara,

Thanks for clarifying my mistake.  As I am running 1.2, I went back and 
verified that, yes,
I have set the QIBM_RPG_JAVA_PROPERTIES environment variable as you describe.

When JNI is being used to start the JVM (as when RPG calls Java),
SystemDefault.properties works for every property _except_
java.version.  See
http://publib.boulder.ibm.com/infocenter/iseries/v5r3/ic2924/index.htm?info/rzaha/sysprop2.htm.

To set the java.version property, use the QIBM_RPG_JAVA_PROPERTIES
environment variable; set it up before the JVM gets started.  You code
the properties just like in the java command (with the initial -D),
separated and terminated by some character (say semicolon).  You need
the separator even with just one property.

   ADDENVVAR QIBM_RPG_JAVA_PROPERTIES VALUE('-Djava.version=1.4;')

See the V5R3 version of the ILE RPG Programmer's Guide
http://publib.boulder.ibm.com/infocenter/iseries/v5r3/ic2924/info/rzajp/sc092507.pdf,
but this support is also available through PTFs for V5R1 (SI10069) and
V5R2 (SI10101).
