Assuming the lists are user dependent..
1)You should run some profiling and load tests.There may be no performance
issue in the first place.
2)Keep the actual content of the lists in application scope and only the ids in
session.Lets say you have to show {"New York","London",Toronto"}; keep an int
array in session{1,2,3}and use the request interceptor or Tiles Controller to
fetch the actual content.

If those lists are not user-dependant, you can put them in application
context. This way, they will be shared by all your users.
If they are user-dependant, I think I would have done a bean that
provides properties that get data from db on the fly.
Of course, if an error occur, it will be in jsp rendering ...
Maybe you can also put in request (not in session) frequently used
values with an interceptor ?
