BEA Jrockit supports both AMD64 and Intel's EM64T (basically renamed AMD64) http://www.bea.com/framework.jsp?CNT=index.htm&FP=/content/products/jrockit/
and Sun's Java 1.5 for "Windows AMD64 Platform" They advertize AMD64, presumably because that's what there servers use, but it should work on Intel's x86_64 (EM64T) also. The release notes have the following: "With the release, J2SE support for Windows 64-bit has progressed from release candidate to final release. This version runs on AMD64/EM64T 64-bit mode machines with Windows Server 2003 x64 Editions." Of course, if the platform is up to you, I'd choose Linux :-) -Yonik On 1/26/06, Peter Keegan <[EMAIL PROTECTED]> wrote: > I'd love to try this, but I'm not aware of any 64-bit jvms for Windows on > Intel.
