用Vaadin配置休眠JPAContainer2.0

我試圖轉換Vaadin演示JPAContainer使用休眠而不是eclipselink。但我似乎無法得到它的工作。用Vaadin配置休眠JPAContainer2.0

這裏是我引用https://vaadin.com/book/-/page/jpacontainer.html

這是試圖運行應用程序時的堆棧跟蹤的文檔：

伊夫包括與MySQL連接器沿着所述休眠庫/ WEB-INF/LIB/

我幾乎整整一天都在搞這樣的事情，並沒有得到它的地方。任何幫手將不勝感激。

在我看來，你的驅動程序不包含在buildPath中。 – 2012-04-07 02:08:27

它位於WebContent/WEB-INF/lib /中，它出現在eclipse中的WebApp庫中 – John 2012-04-07 02:50:52

如何部署Web應用程序？ Eclipse下的Tomcat？ – 2012-04-10 23:17:29

我通過使用早期版本的hibernate 3.x得到了這個工作。最初我使用的是hibernate 4.x，我認爲在該版本中一定會有一些配置更改，不允許我以我嘗試的方式使用。
