RE: URGENT: html:options
I think your collection needs to implement the List interface (use an
ArrayList instead of a vector)

i then had
this gave me an error, setCollection(java.lang.String) cannot be applied to
java.util.Vector
this was a compiler error.
i tried doing,

Re: URGENT: html:options
collection attribute of tag is used to set the name of a bean (in some
scope) that is a collection of the
items off the select-box.
You need to put your Vector into page or request scope to use this tag:
<%
request.setAttribute("items", agencyIds);
%>

Re: URGENT: html:options
hi!
thanks for the reply.
doesn't the jsp import statement followed by the usebean ie,
%@ page import="MyUtils" %>
introduce the agencyIds into page scope.
also with the example you gave me should
shouldn't the value of collections be items, since that is the key you used.
thanks
cheers

Re: URGENT: html:options
create a scripting variable "agencyIds" and a page scope bean "agencyIds". This
created vector is empty.
<% agencyIds= MyUtils.getAgencyIds(); %>
chags the object referenced by the scripting variable, but not the page scoped bean.
You should use something like this, assuming populateAgencyIds(List) adds items to an
existing List :
<% MyUtils.populateAgencyIds(agencyIds); %>
