Недавно я работаю над этим маленьким проектом с Java EE, и мне нужно использовать базу данных Derby, но каждый раз, когда я перехожу в базу данных Service-> и стараюсь подключиться к моей JDBC: Derby, я получаю эту ошибку: < /p>
Невозможно подключиться. Cannot establish a connection to jdbc:derby://localhost:1527//sample using org.apache.derby.jdbc.ClientDriver (java.netConnectException : Error connecting to server localhost on port 1527 with message Connection refused: connect.).
and this exception :
