c:forEach tag

Question

Hi,
I'm trying to use the forEach tag in the jstl in order to display the contents of an Hashtable. The table is written in the session and arrives populated with the results of a SELECT query.
The elements of the table are instances of a class of mine, and I'd like to display some of the fields (all accessible by getters and setters) of this class.
The fact is that if I try to write the elements of the table, I obviously get the class of the elements followed by their ID number (like Object@64383265), but if I try to access a field, I get nothing.
Here is the code reading the elements:
risposta = Hashtable in the session, contains dap.obj.Notizia objects
<jsp:useBean id="notizia" scope="page" class="dap.obj.Notizia" />
<c:forEach var="notizia" items="${risposta}">
     <c:out value="${notizia}" />
</c:forEach>
And if I try to replace the line of output with:
     <c:out value="${notizia.ID}" />
I obtain an error saying:
(...) Unable to find a value for "ID" in object of class "java.util.Hashtable$Entry" using operator "." (null)
If I use
     <c:out value="${notizia.[ID]}" />
no errors and nothing appears..
Do I need to know something about the cast inside the tags of jstl or am I trying to do something wrong?
I admit that these are my first days with jstl, but I've searched among some books with no results. Thanks in advantage for your jelp

Seeing as you are accessing a Map, the object you get back is a Map.Entry
So you can access it as ${notizia.key} to get the hash key, and ${notizia.value} to get the object of type Notizia
<c:forEach var="notizia" items="${risposta}">
<c:out value="${notizia.value.ID}" />
</c:forEach>Cheers,
