Generating Artifacts错误的解决办法

今天尝试反向从myeclipse database explorer 生成pojo和.hbm.xml的时候出现这么一个错误：“Generating Artifacts”

凭借我多年的经验，这个问题是出在找不到驱动上面。于是在环境变量上找寻，但是检查了很久没有发现问题。

最后解决办法：

找到workspace下面的 .myhibernatedata 这个文件，打开它，然后找到configFile，将路径改为hibernate连接数据库的配置文件路径，问题解决！

reSettingsFile=/siliao/hibernate.reveng.xml
configFile=/siliao/cfg/proxool_mysql.xml
createConfigFile=false
addLibs2Classpath=true
baseDaoClass=BaseHibernateDAO
