Hi,

Does anyone know which part of the WMI will give me the Java VM information
(Vendor(s):Sun Microsystems or Microsoft Corporation, Version, etc.)?

I was thinking of using Win32_Product, but there's a warning saying that
only apps installed through MSI would appear in here.

Thanks in advance,
Gavin

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
