YOu can read this on struts-logic doc :
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, you should use :
logic:iterate name="objA" property="hTable" id="objB" indexId="ind" type="ObjB" >
Next element is <bean:write name="objB" property="value.prop" />
[<bean:write name="value.ind"/>]
</logic:iterate>
