Hi,

There is nothing builtin in WMI for this.

For MS JVM, the version number of %SystemRoot%\System32\msjava.dll can
be used (and if the file doesn't exist, MS JVM is not installed).

For Sun's Java Runtime Environment, you can use some script logic for
registry values/keys under
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment
