Looking for com.sap.rfc and com.ibm.sap.bapi Java Libraries

Hi, I'm looking for com.sap.rfc and com.ibm.sap.bapi libraries for java.

At help.sap.com, chapter

"RFC Java Class Library (BC-FES-AIT) -> Installation and Setup" it's written:

"Locate the R/3 Presentation CD. You install the Java RFC components from this CD as part of the installation of SAP Automation."

At first, there're three of Presentation CDs. Second, is that there's no single installation, I mean,

there're a lot of products, no one named like "SAP Automation".

Does anyone know, what EXACTLY I should run from the CD?

Strange, I found already rfc libraries for a lot of languages, all but Java.

Next, in the "BAPI User Guide CA-BFA) -> Examples of BAPI Calls -> Calling BAPIs from Java" code example

the library com.ibm.sap.bapi is used.

Knows anybody, where to get it?
