Tag Library Descriptor files in WEB-INF

I am attempting to develop a JSP application using Struts. In order to do this, both NetWeaver and Struts documentation state that the Tag Library Descriptor (*.tld files) must be placed in the WEB-INF directory of the WAR. In a NetWeaver Web Application Project, I need to map *.tld files so that they will appear in the WEB-INF directory of the resulting WAR. How is this done in NetWeaver?
