how to run servlets using weblogic 6.1?

Hi,
How do i run a servlet using Weblogic 6.1?
i have foolwed the instructions given at the url:
http://e-docs.bea.com/wls/docs61/quickstart/quick_start.html
i'm able to run html and jsp files, by simply following the instructions given for each.
but, i'm not able to do so in the case for servlet.
if i want to run a servlet whose class file "HelloWorldServlet.class" has been copied into the path:
WL_HOME\config\mydomain\applications\DefaultWebApp\WEB-INF\classes
using the url
http://localhost

ort/HelloWorlServlet
what url-pattern value should i give in the web.xml file?
I would appreciate if anyone could help me on this.
