There are a couple concepts to understand here: 1. unless you provide a mapping to your servlet, the Servlet engine won't find it for you. Servlets are not directly loadable. Static files are (as are .jsp's). Servlet mappings are set up in the web.xml. In Tomcat, a default servlet mapping is set up for you for convenience: the directory "servlet" which comes after your context name. So, that would be http://localhost:8080/test/servlet/.
Now that we know that, this brings us to point #2. 2. Either you must provide an alias for your servlet or reference it by its fully qualified name; that being the package + classname. If your servlet doesn't specify a package, then it would just be your ClassName. Given no specified alias and the servlet belonging to package com.mycompany.servlets, your Counter servlet would be access like: http://localhost:8080/test/servlet/com.mycompany.servlets.Counter and if it doesn't have a package: http://localhost:8080/test/servlet/Counter You can provide an alias by adding the following to your web.xml file (inside /test/WEB-INF/ directory): <servlet> <servlet-name>counter</servlet-name> <servlet-class>com.mycompany.servlets.Counter</servlet-class> </servlet> Now you can actually access your servlet like this: http://localhost:8080/test/servlet/counter Notice that even though, in this case, the servlet was part of a package, you can still access it without referring to the package since you specified an alias for the servet. You can do even more if you add your own mapping: <servlet-mapping> <servlet-name>counter</servlet-name> <url-pattern>/counter</url-pattern> </servlet-mapping> Now you can access the servlet without using the default mapping "/servlet/" since you are providing your own mapping: http://localhost:8080/test/counter notice how the "servlet-name" tag within the "servlet-mapping" tag is the same name as we specified in "servlet-name" tag within the "servlet" tag. There are lots more complex examples that you can use by looking at the servlet spec or getting a good book on servlets such as Oreilly's Java Servlet Programming 2nd Edition, but this should get you started with what you need.
