    <url-pattern>/servlet1</url-pattern>
  </servlet-mapping>

    <taglib-uri>/internetbeans.tld</taglib-uri>
    <taglib-location>/WEB-INF/lib/internetbeans.jar</taglib-location>
  </taglib>
</web-app>
如果你是用JB5向导生成Servlet则该文件会自动修改

Answer 1

把class文件放入指定的文件夹即可

Answer 2

在用户apps目录中的web-inf建立web.xml文件，加入如下行说明：<servlet>
    <servlet-name>servletname</servlet-name>
    <servlet-class>classspackage</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>servletname</servlet-name>
    <url-pattern>/servletname</url-pattern>
</servlet-mapping>即可
