急！！tomcat4.1.27下，到设置数据库时报错,详见内部。

已把class12.jar加到common/lib下，设置数据库输入driver,url等后
报错：Failed to load specified JDBC driver. Make sure the driver is in your server's classpath. Since Jive does not work with the "sun.jdbc.odbc.JdbcOdbcDriver" driver, or the "com.internetcds.jdbc.tds.Driver" driver, their use is specifically disallowed.
用oracle,db2数据库试过报同样的错误。用mysql数据库，就不会报这样的错。如何解决啊？？:(
