从Java连接到Oracle DB时出错

Question

有人可以帮我解释为什么我在尝试从java连接到Oracle数据库时收到以下错误....

连接呼叫是:

Connection con = DriverManager.getConnection(
     "jdbc:oracle:thin:@winson.net:1522/hcrod", 
     "manager", "passing");

我收到以下错误:

java.sql.SQLException: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

Answer 1

在类似的情况下,我工作了一个稍微的其他连接字符串: jdbc:oracle:thin:@winson.net:1522:hcrod

真的没有//和有:而不是/

Answer 2

听起来服务器上的端口没有监听，端口 1522。

可以telnet移植成功吗？
