郁闷：在“Generating Artifacts”期间发生了内部错误。

[paradise_java]

在HIBERNATE GENERATING ENGNERING时候报错。
在GOOGLE,BAIDU查了好多，导致错误的原因很多。
看了下LOG：

1.我的HIBERNATE.CFG.XML和PROXOOL.XML都放在"\WEB-INF\CLASSES\"里面
2.proxool-0.9.0RC3.jar，sqljdbc.jar都放在\WEB-INF\lib下

初学HIBERNATE,麻烦几位高手看看怎么解决，昨天弄了1天也没搞定。能解决立即给分，在加也可以

没有高手了嘛？

想当初的CSDN的红红火火，现在竟然变成这样了。。。失望！

[古月一刀2005]

连接数据库的包出现错误！



情况有好多种：1位置，2过时 ，3，版本不对！

[paradise_java]

我用的是PROXOOL连接池，都已经配置好了，放到了WEB-INF/CLASSER下了，驱动是MS SQL 最新的驱动
