I figured it out. I changed my HashMap into a collection and started
iterating over the collection. Since the value object in the HashMap
contains the key also ( the business side is returning a HashMap instead of
a collection btw) , i was able to iterate through the collection and so
typecast each object to its exact data type. Thanks everybody for your help.
cheers,
Amar..

Mike,
Thanks a lot for your help. I am trying to figure out how to typecast the
'value' object into type DataBean so that i can call one of its methods.
Maybe i need to do something fancy to satisfy the compiler and the JVM.
cheers,
Amar..

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:
a.. key - The key under which this item is stored in the underlying Map.
b.. value - The value that corresponds to this key.
So
> <logic:iterate id="itemEntry" property="offerItems" name="someForm"
> scope="session" >
the property itemEntry.key is the key in the hashmap.
the property itemEntry.value is your bean, which you may do something like
itemEntry.value.name
Hope this helps.
