源码是： 
package test; 
import java.sql.Connection; 
import java.sql.DriverManager; public class DB { 
Connection conn; 
public Connection getConn() { 
return conn; 
} 
public DB(){ 
String driver="oracle.jdbc.driver.OracleDriver"; 
String url="jdbc:oracle:thin:@127.0.0.1:1105:orcl"; try { 
Class.forName(driver); 
conn=DriverManager.getConnection(url,"testchen","testchen"); 
System.out.println(conn); 
} catch (Exception e) { 
e.printStackTrace(); 
} 
} 
public static void main(String[] args) { 
new DB(); 
} 
} 就一个连接数据库 使用的是ojdbc14.jar  oracle11g
