Yes, suppose that this map is stored in the scoped variable 'MyMap'. The
expression
${MyMap.blue}
will yield 'sky'. If you want to iterate, consider the following example:
<c:forEach items="${MyMap}" var="entry">
key: <c:out value="${entry.key}" />
value: <c:out value="${entry.value}" />
</c:forEach>
Hope that helps,
