ввод правильного имени пользователя и пароля, получение ORA -01017 :неверное имя пользователя/пароль; вход запрещен

У меня есть конфигурация базы данных оракула в файле tomcat server.xml

<Resource name="jdbc/sgfdb" auth="Container"
          driverClassName="oracle.jdbc.OracleDriver"
          url="jdbc:oracle:thin:@databaseurl:1521:schema"
          username="username" password="password" maxActive="20" maxIdle="10"
          maxWait="-1"
          factory="oracle.jdbc.pool.OracleDataSourceFactory"
          type="oracle.jdbc.pool.OracleDataSource"/>

Затем в моем веб-приложении (spring mvc project )я объявляю это в context.xml

<Context>
 <ResourceLink name="jdbc/sgfdb"
        global="jdbc/sgfdb"
        type="javax.sql.DataSource"/>
</Context>

Я смог подключиться к этой базе данных раньше. Я не работал над ним неделю. Теперь, когда я пытаюсь запустить его, всегда получаю:

SEVERE: Servlet.service() for servlet [action] in context with path [/WebUI] threw exception [Request processing failed; nested exception is javax.persistence.QueryTimeoutException: Could not open connection] with root cause
**java.sql.SQLException: ORA-01017: invalid username/password; logon denied**

Я уверен, что имя пользователя и пароль верны. Кто-нибудь может подсказать, что здесь происходит?
