SessionBean with external library

Hi,

i am developing a session bean, that needs to call an external library. I thought like in WAS 6.20 i could refernce this library.

I am developing with SAP NetWeaver Developer Studio 2.0.4. I found out, that i can put in references in the application-j2ee-engine.xml. But how do i reference a library, that is not visible to the server. How do i add this library to the context of the server.

Thanx
