我正在使用 struts2 开发一个 Web 应用程序。

我已将一项操作的名称 OldNameAction.java 更改为 NewNameAction.java。

现在，当我使用 tomcat 运行应用程序时，出现以下错误：

Action class [oldNameAction] not found - action - file:/C:/path/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/projectname/WEB-INF/classes/struts.xml:155:98

我的 struts.xml 文件如下所示：

<action name="getSimulation" class="newNameAction" method="getSimulation">
            <result name="dnf_andOr">dnf_andOr_simulator.jsp</result>

        </action>

和 applicationContext.xml：

<bean id="newNameAction" class="com.org.action.NewNameAction" scope="prototype">
    </bean>

我使用了“clean tomcat workdirectory”和“clean”选项，但没有成功。任何想法？任何想法，为什么它保留新名称？
