Reference External Java Libraries Across All SW Components/Namespaces

Hi,

I went through "How to Perform SAP Data Lookups Within XI Mappings" By Jerome Delune

While I found it very useful, I could only manage the first three approaches. I could not test the Fourth approach(Reference External Java Libraries Across All SW Components/Namespaces).

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/xi/how to perform sap data lookups within xi mappings

This is because I am using WebAS 6.40 and could not find the additional-Lib folder as mentioned. Please tell me the procedure how to reference External Java Libraries in WebAS 6.40.

Regards,

Dennis
