Just in case anyone is interested, Today I did a test to answer my original question; "Does data in the application and server scopes get stored in the "tenured" generation memory, or the "permanent" generation memory?"
I found that Application, Session and Server scopes all stored their 'data' in the "Tenured" generation space. The "permanent" generation is in fact used just for information about the data, 'classes' etc. Our site is in fact very large (university website) with lots of different classes, and our "permanent" generation was only using about 50 meg of the 250 meg allocated for it. Note that we run JRun4 with the Sun 1.4.2 JVM and Coldfusion 7.
