That solved the problem beautifully. Thanks for the help. As for the conversation over whether this code is better suited as a servlet, the general answer would be yes. However, due to some expected maintenance issues here there has been a decision made to try to limit Java code as much as possible (it is largely a financial matter for maintenance - paying someone who knows JSTL is considered cheaper than a full blown Java developer). Hence, the processing code winds up in a JSP.
