摘要: 帮我看一下下面创建jdbc连接怎么会出错

String driverClasses=com.microsoft.jdbc.sqlserver.SQLServerDriver;
try {
Driver driver = (Driver)Class.forName(driverClasses).newInstance();//这一步了错了
DriverManager.registerDriver(driver);
drivers.addElement(driver);
}
catch (Exception e) {
Log.printEvent("Can't register JDBC driver: " +
driverClassName + ", Exception: " + e,logFile);
}
