RE: Question about iterate tag
Craig,
I did try this way but it still does not work. Since supplier.value is of type
SupplierBean, do I have to specify that anywhere?

When you iterate over a Hashtable (or any other implementation of the Map interface),
the object get for the "id" variable is actually an implementation of
the "Map.Entry" class, not the class of the value of the bean. From this "Map.Entry"
instance, however, you can easily get to the real information:
bean:write name="supplier" property="value.seq_nbr" scope="page"/
This works because a MapEntry has two properties -- key and value -- so we are using
the nested property syntax to effectively call getValue().getSeq_nbr().
Thanks in advance.

I believe you want the bean to be SupplierBean rather than Supplier. Your
request
bean:write name="supplier" property="value.seq_nbr" scope="page"/
seems like it would get translated into
out.print( String.valueOf(supplier.getValue().seq_nbr) );
or something akin to that which is Not At All what you're looking for.

RE: Question about iterate tag
Craig had suggested that I use:
bean:write name="supplier" property="value.seq_nbr" scope="page"/
but unfortunately it is not working.

RE: Question about iterate tag
IT IS UNBELIEVABLE!
I have wasted so much time trying to get this to work and all that was missing in my
JSP was this line:
%@ taglib uri="/Web-inf/struts-logic.tld" prefix="logic" %
The strange part is that I was not getting any error in the log files saying undefined
tag or anything.
I appreciate all the help I received :)

nope, not that strange.
if you viewed the source of your page, you should be able to see your
logic tags, still sitting there, unprocessed as text.
The container will only complain about undefined tags if there is a .tld
defined with
a prefix at the top of the page (ie the struts-logic tags). Otherwise it
treats everything
else as plain text.
