public static void main(){
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
Connection conn = DriverManager.getConnection("jdbc:microsoft:sqlserver://127.0.0.1:1433","sa","");
}
}

D:\Program Files\Xinox Software\JCreator LE\MyProjects\research\research.java:6: unreported exception java.lang.ClassNotFoundException; must be caught or declared to be thrown
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");

D:\Program Files\Xinox Software\JCreator LE\MyProjects\research\research.java:7: unreported exception java.sql.SQLException; must be caught or declared to be thrown
Connection conn = DriverManager.getConnection("jdbc:microsoft:sqlserver://127.0.0.1:1433","sa","");

因为数据连接的方法将异常抛出，调用者必须try{}catch{}

把public static void main()改成
public static void main(String[] args) throws Exception也行。
