说是我的路径错了，但是正确的路径是什么啊？求指点

Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");是这句吗？

对

我是这么写的

你加没加上我不知道啊，反正编译的时候就是没有找到你驱动的jar包，这是确定的。或者是你没把jar包build path 进去，或者是jar包版本有问题

哦，对了，jar包怎么去哪弄啊？可能是我的jar包不对，请问我怎么才能知道用什么jar包？

汗。。。SQLServer就有SQLServer的驱动，Microsoft SQL Server JDBC Driver，这还要看你的sqlserver版本

我没用SQLServer，我用的mysql。和mysql front。你能把msbase.jar,mssqlserver.jar,msutil.jar这几个jar包发给我吗？我的邮箱sushuai2008@qq.com,谢谢了

网上搜啊老大，我没有
