You can't use a dynamic 'var', but you can use a different syntax of
<c:set> that lets you set the values of elements in a Map, as in
<c:set target="${myMap}" property="${keyName}" value="${newValue}" />
Then, you can refer to what you have just set with expressions like
${myMap[keyName]}
Hope that helps,
