How to iterate session variable

[Rushikesh Thakkar]

Hi all,

I am trying to iterate the a session variable of type HashMap<String, List>
using the following code:

   <s:iterator value="#session.physicalArchives">
       <s:property value="key" />
       <s:property value="value"/>
   </s:iterator>

It is not producing any markup. I have made sure that the variable is
present in the session and has valid values within.
Kindly help me..
