是否有某种类型的默认hibernate日志配置与tomee一起提供？使用hibernate从独立应用程序访问mysql表时，我没有收到任何错误。但是，当我将相同的代码移植到运行在tomee中的Web应用程序时，我收到的错误如下。它似乎是由于某些东西被配置为使用hsqldb来执行hibernate日志记录。但是我从来没有在hibernate或tomee中做过任何这样的配置。

TomEE为您提供默认数据源（hsqldb）。我猜你使用javax.persistence属性而不是jta-data-source / non-jta-data-source标签在你的持久性单元中设置你的mysql连接。
