Ivaylo Ivanov told me, XI is not part of Sneak Preview.
But the Document SAP NetWeaver in the real world Part III: SAP Exchange Infrastrucure says in chapter prerequisites/installed Software:
To implement the solution described in this article, you need SAP® Web Application
Server 6.40 for Java and SAP Exchange Infrastructure 3.0 installed in the Web
Application Server (WebAS). In order to access the XI Integration Builder, you need to
have Java TM WebStart version 1.4.2 installed on the local computer.
An than sneak preview is mentioned:
SAP Web AS Java/Developer Studio 6.40 - Sneak Preview Edition
Is this a misunderstanding?
Thanks in advance
