Thanks for the prompt reply, Vasmi. I've tried both adding the jar file as a module in the app server (and defining the dependency in my geronimo-web.xml), and I've also tried including the JAR in the WEB-INF\lib folder of the war file as well. I've attached a war file which uses the latter method. To reproduce the error, try accessing http://localhost:8080/cityLookup/CityLookupServlet?s=chi
