.是什么原因,数据库在我本地,已经启动.
3个驱动JAR包我是从别的机器上考过来的.放在工程的CLASSPATH下.
给你的sqlserver打上sp3补丁
这个得看你的连接数据库的代码了。好好看看它。错误提示是说你的连接数据库出错。
如果你的服务器是windows2003的，sql要打到sp4才可以！
我是WINDOWXP,打到SP3,
数据库连接
driver:com.microsoft.jdbc.sqlserver.SQLServerDriver
user:sa
passwd:sa
Class.forName(driver).newInstance();
conn = DriverManager.getConnection(url, user, passwd);
还是一样的错误
sqlserver是2000的
url:jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=DB_JXC
