我开发了一个基于 Spring 的小型 Web 应用程序来测试 Spring RMI。在那里，我创建了一个简单的服务来根据输入参数生成问候消息并将其返回给客户端。我的弹簧上下文文件如下所示：
<bean id="registry"
class="org.springframework.remoting.rmi.RmiRegistryFactoryBean">
<property name="port" value="4777"/>
</bean>
<bean id="greetingService" class="com.greeting.GreetingServiceImpl" >
</bean>
<bean class="org.springframework.remoting.rmi.RmiServiceExporter"
p:service-ref="greetingService"
p:serviceName="greetingRmiService"
p:serviceInterface="com.greeting.GreetingService"
p:registry-ref="registry"
/>
首先，我在运行 tomcat server 7 的本地 pc 中部署了这个应用程序，并且部署成功。然后我把这个应用的war文件上传到了Openshift tomcat 7 DIY服务器。但它没有部署我的应用程序并在日志文件中给出了这个错误。

如何修复此错误并在 Openshift 中部署此应用程序？
谢谢！
