How to add library to buildspace in CBS?

Hi,

We have a Web Dynpro application that uses com.sap.security.api library and are having a problem figuring out how to build it in CBS. We can build the application locally by providing the proper classpath, but it will not build in CBS because the library cannot be found

Apparently, this library isn't in the SAP-JEE component included in the CBS as a default part of the configuration. How do you include a SAP library (jar) in an application built in CBS? Is there a component dependency we need to define in SLD and a SCA file we have to import? Or, is this done in some other way?

Thanks.

Rob
