JDBC连接oracle,奇怪问题
错误:
java.sql.SQLException: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
The Connection descriptor used by the client was:
localhost:1521:xe


我的源码:
String strDriver = "oracle.jdbc.driver.OracleDriver ";
String strURL = "jdbc:oracle:thin:@localhost:1521:xe ";
String user = "system ";
String password = "yd ";

Connection conn = null;

try {
Class.forName(strDriver);
conn = DriverManager.getConnection(strURL,user,password);
System.out.println( "连接成功! ");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

服务中:oracleServerXE ----------------那实例号应该是XE吧?

[解决办法]
应该这里错了:1521:xe
你数据库名叫什么,好象不是XE吧?
端口号后面接的是数据库名，也就是实例名
