Any Hashmap examples used in jsp page?

[Dudley [EMAIL PROTECTED]]

Hi all, 

Could anyone please point me to where i can find some examples using
hashmaps in a jsp with struts...
Instead of using a whole bunch of logic equal tags all the time, i need a
way to evaluate a collection, looking for a specific key value, then show or
hide the relevant input boxes on my jsp..
any help...please!!!???
