RE: Any Hashmap examples used in jsp page? - still not working

["Dudley Butt@i-Commerce" <Du...@za.didata.com>]

Hi all

Still not getting this hashmap thing write...here is what i'm trying to do.
I have a hashmap with a list of key-value pairs.

I don't want to go thru each element and list it, i just want to evaluate
the equivalent Java code : if (map.containsKey(LIC.LINE_TYPE)){ ....
I want to find out whether the map has a certain key in it, without having
to loop the whole way. I'm trying to use a logic:equals tag

help!!!

 Maybe it's a dumb idea, but that's never stopped me before. =:]

 I used an ArrayList of String[]s and that worked fine. Thanks.
