N久么用 Oracle 10G 使用JDBC访问出现以下错误
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:PLSExtPro1c

解决的方法是：
jdbc:oracle:thin:@localhost:1521:PLSExtProc
PLSExtProc 是默认的数据库id
到 E:\oracle\product\10.2.0\db_1\NETWORK\ADMIN tnsnames.ora
里面就看 SID的值。 (SID = PLSExtProc)
