You need to have a web.xml inside your WEB-INF directory, which should in turn be in your webapp root directory. This is where you need to declare your servlet, and map it to one or more URL patterns. You should see the Servlet spec for more details. Also check out the example webapps that come with Tomcat. -- Tim Moore / Blackboard Inc. / Software Engineer 1899 L Street, NW / 5th Floor / Washington, DC 20036 Phone 202-463-4860 ext. 258 / Fax 202-463-4863 > > Thanks so very much for your assistance, it is genuinely appreciated. > Jackie > > At 12:39 PM 2/6/2003, you wrote: > >What version of Tomcat are you using?
