try something like:
<%
Collection c =
org.ellism.tir.util.DatabaseConstantsAdapter.getInstance().getProductLines();
request.setAttribute("colName",c);
%>
and then:
<logic:iterate id="..." collection="colName"...
</logic:iterate>
you can alse put your collection into the jsp scope
variable somewhere in your action.
hope it helps.
