Library Project and References Problem

Hi,

in Netweaver Developer Studio I would like to add references to a library project.

In this article is described how to do that:

At point 2 is described that I should be able to select from Installed Libraries – The default libraries expected to be available on the J2EE Engine.

But - in my case - the dialog that appears contains no references.

Do you know how I get the default libraries to be shown for selection?

Thank you and best regards

Marcus
