About Java Virtual Machine

Can Someone help me for Java VM?
How can I see version of JVM and JDK on
UNIX AIX 4.3?

You can use "smitty" from any terminal.
Once in smitty, select:
Software Installation and Maintenance

then select:
List Software and Related Information

then select:
List Installed Software and Related Information

then select:
List Installed Software

in the first entry filed on the right (the
cursor should already be there) just type:
Java*

and you should get a list of all Java components.
One of those output lines should look somthing
like:
Java_dev2.rte.bin 1.2.2.10 C Java Runtime Environment

You can also, simply use the Java command flags
that display the version:
java -version
java -fullversion
This is easy, doesn't require root, and works
on all platforms. Enjoy...
