本人在使用Hibernate生成映射文件及POJO时遇到的问题：“org.hibernate.exception.GenericJDBCException: Could not get list of tables from database. Probably a JDBC driver problem.
”

版本信息：Hibernate3.1 ；MyEclipse6.0M1； Oracle8。

查看Eclipse workspace\.metadata\.log文件产生如下日志信息：

解决思路：按照提示信息描述的Probably a JDBC driver problem.开始更换OracleJDBCDriver classess12的各种版本，由于数据库版本为8使用8的驱动明显不行，逐渐升高版本至(10.2.0.3) 问题便解决了。可以到这个地址下载最新的Oracle驱动程序http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/jdbc_10201.html
