servlet类似
servlet配置为：
<servlet>
<servlet-name>Demo01_OutWrite</servlet-name>
<servlet-class>com.cjq.response.Demo01_OutWrite</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Demo01_OutWrite</servlet-name>
<url-pattern>/servlet/Demo01_OutWrite</url-pattern>
</servlet-mapping>
jsp配置对外访问路径
<servlet>
<servlet-name>forward</servlet-name>
<jsp-file>/jsp_Tag/forward.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>forward</servlet-name>
<url-pattern>/forward/*</url-pattern>
</servlet-mapping>
相差点就是<servlet-class> 改成<jsp-file>
