Not tested below but should be ok. the .?? is because I don't know what 
kind of Objects are in the List. If they are beans in the ArrayList just 
.whateverProperty where whateverProperty of course equates to a getter 
(getWhateverProperty() in the bean)

<c:forEach items="${yourFormBean.yourMap}" var="map">
     The Key: <c:out value="${map.key}"/><br/>
     <c:forEach items="${map.value}" var="item">
	Item in List: <c:out value="${item(.??)}/><br/>
     </c:forEach>
</c:forEach>
