Well, your suggestion almost worked. I got the keys and values printed out but
the "test" wouldn't work!
Here is what I tried to do:
<c:forEach items="${fRoles}" var="item">
<c:if test="${item.key} == 'manager'">
Found manager
</c:if>
</c:forEach>
Is the syntax right? Anyway the above code doesn't find the key manager while
I can print it out using your suggestion.
I also tried this and it didn't work...
<c:choose>
<c:when test="${ not empty fRoles['manager']}" >
Found formRoles manager
</c:when>
<c:otherwise>
NOT Found
</c:otherwise>
</c:choose>
Do you have any other suggestions?
Thanks for your help
NK

What happens when you try:
<c:forEach var="element" items="${fRoles}">
<c:out value="Key=${element.key}, Value=${element.value}"/>
</c:forEach>
instead of logic:iterate
