Help Req on Iterate Tag using HashMap

[Shakti]

Hi All,
I am keeping some table data in a HashMap .
My Table is in this form :
UID #    EMP Details
               -Date of joining
               -Date of birth
               -Misc Detail

Now i am creating an EMPDetails bean and storing the bean in a hash map with UID # as 
the key.

Can anyone plz tell me how to show the data in a tabular form in jsp using iterate tag 
. I am unable to make out as how to 
iterate the EMPDetails bean which i am getting as value .

Thanks & Regards,
Shakti
