在配置weblogic数据源和连接池时，由于建立连接池采用的weblogic的默认sqlserver jdbc驱动程序weblogic.jdbc.sqlserver.SQLServerDriver,这给我下面的工作带来很大的麻烦。我在进行session.save()时，提示错误 JDBC error: Unsupported method: Connection.prepareStatement ,很是让我纳闷，百思不得其解，后google一下，得到了bea 工程师的解答，如下:
 Well, that's clearly one of them. I would contact Hibernate/Plum Tree
 about this, and ask how many JDBC drivers they've tested this with.
 I would venture an educated guess that many JDBC drivers will not
 be able to completely implement all the JDBC 3.0 methods in the
 spec's wishlist.... MHO,

    可以看出，bea提供的sqlserver驱动没有完全实现 jdbc的方法，而hibernate3却调用了Connection.prepareStatement 方法，碰巧该方法不实现，就出现上述错误。
