PAM Clarification Please - Installing Netweaver 7.0 on Win Server 2008 x64


I hope someone here can help clarify SAP's PAM documentation ( regarding Netweaver 7.0. We are currently running EP7SP16 on Windows Server 2003 x32. We are getting ready to install a whole new batch of portal servers (unrelated to the ones we already have in place) and I was wondering if it was supported, by SAP, to install NW 7.0 on Windows Server 2008 x64.

So, I went to the trusty 'ol PAM to look. Here is where the confusion started. It says Windows Server 2003 x64 is supported, but that Windows Server 2008 x64 is not, at least until Sun releases a 64-bit version of their 1.4.2.x JDK.

The reason I'm confused is I don't understand what the difference is between running Sun's 32-bit 1.4.2.x JDK on Server 2003 x64 as opposed to running the same JDK on Server 2008 x64. Why is 2003 supported and 2008 is not?



p.s. - Forgot to mention I already read OSS Note #1054740 which talks about 2008, but it didn't really help me in clearing up this question, beyond saying that it does work.

I understand that there is no 64bit 1.4.2 JDK, but the PAM says running Sun's 32bit 1.4.2 JDK on Windows 2003 64bit is supported. So, why wouldn't the same hold true for Windows 2008 64bit?

The reason for that is: 1.4.2 is already EOL´ed, SAP has a special contract with Sun to still support that old/ancient version. They won´t support it under Windows 2008 because this would require additional certification (see
