Where can I download the dependencies/jars needed for java mapping in SAP PI 7.5?

I want to build a java mapping, but I need different JARs. This page contains information about the needed JARs, but I can't find any of the JARs themselves:

I can't find anything in the marketplace. I use SAP PI 7.5
