Answer 1

最后我找到了解决方案，在windows中我们需要先加载类，然后加载jar文件。

一样（这真是奇怪！）

set CLASSPATH = %<project_name>%\classes;%<project_name>%\lib\java\ant-antlr-1.6.5.jar;.... 

除了我们需要包括类

include_class '<your class>.persistence.HibernateUtil' 

感谢所有帮助。

Answer 2

我怀疑你有jar文件，包括一个休眠罐，在LIB或者是由Rails的自动加载一些其他的文件夹2.3

看看

您可能仍然需要在他的评论中包含jens所描述的要求。
