In a Struts Action, I place a Map in session scope depending on what
year the user has chosen-- there may be Maps there named 2002accounts,
2001accounts, etc.

Thanks for jogging my memory... You can construct the key, but you lose

Another approach would be to maintain a map of maps (keyed by year) instead of
multiple free standing maps. Something like:
accountMap: {2001={...}, 2002={...}, ...}
So your loop might look like:
c:forEach var=account items=${accountMap[year]}

;-) I hate to make it more readable, but you should be able to do:
c:forEach items=${accountMap[accountForm.map.year]} var=account
