当我创建一个webapi时，我必须在web.xml中声明相关的class/url

<servlet-mapping>
        <servlet-name>myServlet</servlet-name>
        <url-pattern>/myServlet.htm</url-pattern>
        <!-- WebApi -->
        <url-pattern>/Timbrature2/*</url-pattern>
        <url-pattern>/Timbrature2.json/*</url-pattern>
        <url-pattern>/Timbrature2.xml/*</url-pattern>
        <url-pattern>/Timbrature/*</url-pattern>
        <url-pattern>/Timbrature.json/*</url-pattern>
        <url-pattern>/Timbrature.xml/*</url-pattern>
        <url-pattern>/TimbratureMobile/*</url-pattern>
        <url-pattern>/TimbratureMobile.json/*</url-pattern>
        <url-pattern>/TimbratureMobile.xml/*</url-pattern>
        <url-pattern>/$metadata</url-pattern>
    </servlet-mapping>

但是如果我的webapp从jars动态代码加载，我可以添加一个“新”类来用作REST端点吗？
阅读Apache文档，尝试各种配置，但一无所获
