    <!-- The mapping for the JSP servlet -->
    <servlet-mapping>
        <servlet-name>jsp</servlet-name>
        <url-pattern>*.jsp</url-pattern>
    </servlet-mapping>

    <servlet-mapping>
        <servlet-name>jsp</servlet-name>
        <url-pattern>*.nature</url-pattern>
    </servlet-mapping>


    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>index.nature</welcome-file>
    </welcome-file-list>


와 같이 설정하면 .jsp .nature 는 모두 jsp 파일로 인식한다.
