This is documented in the logic taglib reference. Here's the relevant section:
-----
Normally, each object exposed by the iterate tag is an element of the
underlying collection you are iterating over. However, if you iterate over
a Map, the exposed object is of type Map.Entry that has two properties:
key - The key under which this item is stored in the underlying Map.
value - The value that corresponds to this key.
So, if you wish to iterate over the values of a Hashtable, you would
implement code like the following:
<logic:iterate id="element" name="myhashtable">
Next element is <bean:write name="element" property="value"/>
</logic:iterate>
-----
Hope this helps.
