运行MVC spring应用程序嵌套异常时出错是org.hibernate.HibernateException：未找到方言类：org.hibernate.dialect.MySQL5Dialect

Question

我没有在我的网络应用程序中使用Maven。我已经发布了以下我在类路径中包含的jar的截图。

运行应用程序时，我收到以下错误 -

javax.servlet.ServletException: Servlet.init() for servlet employee threw exception
    org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:108)
    org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:379)

Employee-servlet.xml有以下bean条目 -

以下是database.properties

的屏幕截图

我检查了jar5 hibernate-3.2.4.ga.jar中是否存在MySQL5Dialect类，但不确定为什么它仍然会抛出错误。

任何帮助将不胜感激。
