我開發了一個基於Spring的小型Web應用程序來測試Spring RMI。在那裏，我創建了一個簡單的服務，根據輸入參數生成問候消息並將其返回給客戶端。我的Spring上下文文件看起來像這樣：openshift中的Java RMI端口綁定錯誤
<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"
/>
首先我在本地PC上運行Tomcat服務器部署7本應用程序並將其成功部署。 然後我把這個應用程序的war文件上傳到Openshift tomcat 7 DIY服務器。但它沒有部署我的應用程序，並在日誌文件中給出了這個錯誤。

如何修復這個錯誤，並得到部署在Openshift此應用程序？
謝謝！在使用
我已經運行「netstat a | grep $ OPENSHIFT_INTERNAL_IP」來檢查當前正在運行的端口。但港口4447不在那裏。我也隨機嘗試了不同的端口（1099,9999等）。但他們沒有工作。它嘗試所有不同的端口是不實際的。你有沒有看到**權限被拒絕**異常。所以我想這是關於openshift服務器端口綁定的權限。有關於此的任何想法？ – 2013-04-29 04:37:01
錯誤消息中的端口號是4777，但'權限被拒絕'表示您需要設置Windows防火牆規則。 – EJP 2013-04-29 04:51:33
感謝您的幫助！是的，可能是防火牆是問題。但我認爲我們沒有權限在openshift服務器中以用戶身份更改防火牆設置。 – 2013-04-29 09:24:41
