在Ubuntu上的Amazon EC2上的Tomcat 7中部署Web应用程序

Question

我正在尝试在ubuntu上的外部虚拟机Amazon EC2上的tomcat 7中部署我的Web应用程序，但我总是遇到错误。我正在我的计算机上运行Web应用程序，它可以运行。

错误：

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.test.registration.dao.UserDAOImpl] for bean with name 'userDAOImpl' defined in file [/var/lib/tomcat7/webapps/ServerApp/WEB-INF/classes/com/test/registration/dao/com.test.regist$

这是我的主要xml文件：

我部署一个简单的程序HelloWorld，它的工作原理。 我的春季版是3.2.9RELEASE。

Answer 1

我在data.xml中添加了字符串：

<bean id="userDAOImpl" class="com.test.registration.dao.UserDAOImpl" /> 

我也删除了所有俄罗斯评论！现在它有效！
