WLS 7.0 uses BEA's own JRockit virtual machine. Can't remember 100% sure if 6.1 used JRockit already, but I'd reckon the Sun JVM was the default.

Actually, the default install of WebLogic 7.0 ships with Sun's JVM, though you can also download versions of WLS that ship with JRockit.

I'd think VM is provided (and supported) by respective vendors - HP (for HP-UX), IBM (for AIX), or get it from Sun if one is available for each of the target platforms.
May I ask the reason for your question, and/or how this is important..?

You are right if you consider WebLogic offerings across various platforms. I tend to assume Intel unless the poster specifies otherwise...

Hi,
The default vm shipped with WL7 sp1 is Java(TM) 2 SDK, Standard Edition Version 1.3.1, but you can change it editing the script startWLS under:
%bea_home%\weblogic700\server\bin
I suggest you to download JRockit8 from BEA�s site as you gain performance using it with WL.
regards.

The main benefit of JRockit is concurrent GC, which is now part of HotSpot in 1.4. I would be interested to see a comparison between JRockit 8 and HotSpot 1.4 for various types of Applications.
I like this quote from BEA about JRockit 8:

Bob Griswold, Vice-President and General Manager of BEA's Java Runtime Group:

It's the world's fastest JVM. We've made that claim before, but now it really is
