Mule ESB - 小服務程序：入站端點錯誤

Question

在我的mule應用程序中，我用Servlet入站端點替換了HTTP入站端點，因此我可以在JBoss上部署mule應用程序。現在，當JBoss啓動時，我收到以下錯誤消息：

2012-08-16 12:13:00,416 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/oms]] (main)

一定要聲明servlet命名空間：

xmlns:servlet="http://www.mulesoft.org/schema/mule/servlet" 

... 

http://www.mulesoft.org/schema/mule/servlet http://www.mulesoft.org/schema/mule/servlet/current/mule-servlet.xsd 

，並在你的類路徑中的Servlet運輸JAR。
