セキュア ゲートウェイを使用して、Bluemix アプリ (Java liberty プロファイル) をオンプレミスの db/as400 に接続しようとしています。すべての接続を拒否または許可しても、エラー メッセージは変わりません。アプリからのリクエストがセキュア ゲートウェイ クライアントに到達していないようです (また、接続が拒否されたことを示すメッセージが sgw クライアントに表示されません)。
どうすればそれを解決できますか? これはコードです:
DB_SERVERNAME=jdbc:as400://xxx-xx-xxx-x.integration.ibmcloud.com:15XXX/dbname
try {
Driver driver = new com.ibm.as400.access.AS400JDBCDriver();
DriverManager.registerDriver(driver);
System.out.println("Driver Loaded Successfully ...");
dbConn = DriverManager.getConnection(DB_SERVERNAME, DB_USERNAME, DB_PASSWORD);
System.out.println("Connected...");
} catch (SQLException e) {
e.printStackTrace();
}
エラーメッセージは次のとおりです。
Driver Loaded Successfully ...
