java - 如何修复 OC4J 中的资源未找到错误？

Question

我正在尝试在 OC4J 上部署 Web 应用程序，尽管我已严格按照说明进行操作并且部署过程顺利进行，但我仍然收到 500 错误(如下)。我是 OC4J 的新手，所以我希望得到一些关于要查看和修改内容(XML/设置/等)来解决此问题的提示。这是实际的错误，以防万一:

500 Internal Server Error

看起来你的index.jsp重定向到了你的login.do Struts Action；但您的应用程序未配置为将 .do url 重定向到 Struts。 Struts Action Servlet 是否配置为负责所有 *.do url 映射？请在 web.xml 配置文件 (WEB-INF\web.xml) 中查找与此类似的条目:

<servlet>
    <servlet-name>action</servlet-name>
    <servlet-class>
        org.apache.struts.action.ActionServlet
    </servlet-class>
    <init-param>
        <param-name>config</param-name>
        <param-value>
         /WEB-INF/struts-config.xml
        </param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

以及到 servlet 的映射，如下所示:

<servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>/*.do</url-pattern>
</servlet-mapping>
