数据库如下:
package xjglxt;
import java.sql.*;
public class DataBaseManager
{
Connection con;
ResultSet rs;
Statement stmt;
public DataBaseManager()
{
try{
//DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
//con=DriverManager.getConnection("jdbc:oracle:thin:@happy:1521:myoracle","maimihui","maimihui");
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver" );
con=DriverManager.getConnection("jdbc:odbc:ss","sa","1234");
stmt=con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
}
}
}
那如果把它起掉了,还是有出现问题啊,没有了类啊.那怎么办啊?
