JPA 2.0 Provider Hibernate 在为实体管理器工厂准备配置时抛出异常，我使用的是 DB2 v9.5 数据库和 DB2 v9.5 JDBC type 2 驱动程序.

The JPA 2.0 Provider Hibernate is throwing exception while preparing configuration for entity manager factory, I am using DB2 v9.5 database and DB2 v9.5 JDBC type 2 driver .

java.sql.SQLException: [IBM][JDBC Driver] CLI0626E  getDatabaseMajorVersion is not supported in this version of DB2 JDBC 2.0 driver.

推荐答案

看代码:有一个未记录的hibernate.temp.use_jdbc_metadata_defaults属性，设置为false 可能会有所帮助:

From looking at the code: there is an undocumented hibernate.temp.use_jdbc_metadata_defaults property, setting it to false may help if you can't change JDBC driver:

<property name = "hibernate.temp.use_jdbc_metadata_defaults" value = "false" />
