Oracle 10g Express Editionに接続しようとすると、エラーが発生します。
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
私のサンプルコード:
Class.forName("oracle.jdbc.OracleDriver");
Connection connection = null;
connection = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe", "mk119", "mk119");
Statement stmt = connection.createStatement();
データベース内:
SQL> connect mk119
