Why do I get the 404 error message "The requested resource is not available"?
or "The requested object does not exist on this server"?
If you get either of these errors on a servlet, check the servlet's entry in the web.xml. The entry should be similar to the following:
<servlet> <servlet-name>myServlet</servlet-name> <servlet-class>org.alpha.beta.MyServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>myServlet</servlet-name> <url-pattern>/MyServlet</url-pattern> </servlet-mapping>
The name can be any name as long as it is the same in both mappings. The class must be the fully qualified class name. The pattern must be a pattern that matches the URI that invokes the servlet. In this case, the pattern matches the URI =http://localhost:8081/MyServlet=.
