我快要吐血了，帮帮忙啊。hibernate使用，cannot open connection

[c9714052]

我参照http://www.hibernate.org.cn/88.html学习hibernate的使用方法，sqlserver的驱动是setup.exe得来的三个jar文件，所以在hibernate.properties中改成自已的
## JSQL Driver
hibernate.connection.driver_class com.microsoft.jdbc.sqlserver.SQLServerDriver
出错提示为：
et.sf.hibernate.JDBCException: Cannot open connection

我用mysql也试过，也出现同样问题，已经搞了两天了，哪位大侠帮帮忙啊。

用ms的驱动要把那三个jar并成一个
另外看看你的驱动是否在类路径里

[c9714052]

不行啊，我在jbuilder里把三个jar都放到一起，取了个名叫mssqlServer了，已经引用了这些jar，不然出错的是找不到驱动程序的错误。
