When you iterate over a Hashtable (or any other Map), the elements of
the iteration are of class "Map.Entry", which has two properties --
"key" and "value".
<logic:iterate id="impl" name="loadImpl" property="impl">
The curent value is <bean:write name="impl" property="value"/>
</logic:iterate>
However, to accomplish what you are doing above, a Hashtable seems like
overkill -- if you used an ArrayList or Vector instead, the iterator
would be on the elements themselves, and you would not need any extra
property accessors.
<logic:iterate id="impl" name="loadImpl" property="impl">
The current value is <bean:write name="impl"/>
</logic:iterate>
