使用vaadin和orm的web应用程序（来自可视化范例）不'；t work-java.lang.NoClassDefFoundError:org/orm/PersistentException

我的情况是：

• orm.jar和从可视化范例项目导出的类（java构建路径中的orm.jar）
• 使用Vaadin框架创建的用户界面
• 本地主机中的SQL server（XAMPP）
• 使用EclipseEE、Java和DAO模式

我正在创建一个web应用程序。我使用的是Apache tomcat 7，当我通过用户界面填写数据以创建类别时，在服务器运行的情况下，通过单击“创建类别”按钮（这将在数据库中创建类别），这不会执行任何操作，并显示以下错误：

java.lang.NoClassDefFoundError:org/orm/PersistentException
