<jsp:useBean id="agencyIds" type="java.util.Vector" scope="page" />
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); %>
