iterating of collection of HashMapsusing logic:iterate

Hi All,
I have hashmap with key/value but the value in this
hashmap is another hashmap.
How can I iterate over all the values using
logic:iterate.

HashMap h1 = new HashMap();

String id=1;
HashMap h2 = new HashMap();
h2.put(id,"123");
h2.put("key1","456");
h2.put("key2","789");

then I make entry to h1 like

h1.put(id,h2) and so on...more entries added to h1.

Now I want to iterate thru all the values of h1.

Please note that I am interested only in values of the
h2 and NOT the keys.

Thanks in advance for your help

Vinod

<% 

Map  cuurentMap=((Map.Entry )currentEntry).getvalue();

PageContext.setAttribute("cuurentMap",cuurentMap);

%>

<logic:iterate id="currentvalue" collection="cuurentMap">

// here u need to process the entries 

</logic:iterate>

Well If you would like to avoid scriptlets(which is what is suggested in the
second mail by Pradyumna then you could simple do...

<logic:iterate name="h1Attribute" id="entry">
  <logic:iterate name="entry" property="value" id="h2Entry">
     <bean:write name="h2Entry" property=value />
  </logic:iterate>
</logic:iterate>
