java - 具有 vaadin 和 orm(来自视觉范例)的 Web 应用程序不起作用 - java.lang.NoClassDefFoundError : org/orm/PersistentException

Question

我的情况是:

• orm.jar 和从可视化范式项目导出的类(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 服务器 (XAMPP)。
• 使用 Eclipse EE、Java 和 DAO 模式。

我正在创建一个网络应用程序。我正在使用 Apache tomcat 7，当我通过用户界面填写数据以创建类别时，在服务器运行时，通过单击“创建类别”按钮(这应该在数据库中创建一个类别)，这不起作用任何东西，并显示以下错误:

java.lang.NoClassDefFoundError: org/orm/PersistentException
