Tomcat Servlet映射：为什么示例目录在url中而不在web.xml中

Question

After installing Tomcat you can browse http://localhost:8080/ examples /servlets/servlet/HelloWorldExample

Why it isn't http://localhost:8080/servlets/servlet/HelloWorldExample

since examples is not refered to in Servlet-Mapping ?

<servlet-mapping>
    <servlet-name>HelloWorldExample</servlet-name>
    <url-pattern>/servlets/servlet/HelloWorldExample</url-pattern>
</servlet-mapping>

Answer 1

Maybe this answers:

Tomcat provides a number of excellent servlet examples in "\\webapps\\examples". The servlet source files are kept under "\\webapps\\examples\\WEB-INF\\classes", together with the compiled classes. To run the examples, start Tomcat server. Issue URL http://localhost:8080/examples .

Answer 2

examples is a context path for examples web application deployed on Tomcat. Only for ROOT context you have the same url in servlet mapping and servlet url.
