Constructing key to an object in session scope
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.
Now to display the contents of the Map, I tried:
<c:forEach items="${year+'accounts'}" var="account">
org.apache.jasper.JasperException: An error occurred while evaluating
custom action attribute "items" with value
"${accountForm.map['year']+'accounts'}": An exception occured trying to
convert String "accounts" to type "java.lang.Long"
How can I convince it that '2002' is just a String? I've tried other
variations, and sometimes it complains about a Double instead of a Long.
I tried flipping the order so it's 'accounts2002' but I got the same
error. I bet this is very simple and I'm just not awake yet...

Maybe:
<c:set var="mapName" value="${year}account"/>
<c:forEach var="account" items="${sessionScope[mapName]}">
