Grailsでプールの問題の初期接続を作成できません

Question

先輩がリモートのOracle JDBCを作成しました。データベーススキームにアクセスするには特定のWiFiに接続する必要があります。私は以下のように私のDataSource.groovyを設定にもかかわらず：

dataSource { 
pooled = true 
jmxExport = true 
driverClassName = "oracle.jdbc.OracleDriver" 
username = "test" 
password = "pass"} 

hibernate { 
cache.use_second_level_cache = true 
cache.use_query_cache = false 
} 

environments { 
development { 
    dataSource { 
     dbCreate = "create-drop" // one of 'create', 'create-drop', 'update', 'validate', '' 
     url = "jdbc:oracle:thin:@10.42.0.1:1521:xe" 
     username = "test" 
     password = "pass" 
     driverClassName = "oracle.jdbc.OracleDriver" 
     dialect = imocha.hibernate.dialect.Oracle11gDialect 
    } 
} 
test { 
    dataSource { 
     dbCreate = "update" 
     url = "jdbc:oracle:thin:@10.42.0.1:1521:xe" 
     username = "test" 
     password = "pass" 
     driverClassName = "oracle.jdbc.OracleDriver" 
     dialect = imocha.hibernate.dialect.Oracle11gDialect 
    } 
} 
production { 
    dataSource { 
     dbCreate = "update" 
     url = "jdbc:oracle:thin:@10.42.0.1:1521:xe" 
     username = "test" 
     password = "pass" 
     driverClassName = "oracle.jdbc.OracleDriver" 
     dialect = imocha.hibernate.dialect.Oracle11gDialect 
     properties { 
      // See http://grails.org/doc/latest/guide/conf.html#dataSource for documentation 
      jmxEnabled = true 
      initialSize = 5 
      maxActive = 50 
      minIdle = 5 
      maxIdle = 25 
      maxWait = 10000 
      maxAge = 10 * 60000 
      timeBetweenEvictionRunsMillis = 5000 
      minEvictableIdleTimeMillis = 60000 
      validationQuery = "SELECT 1" 
      validationQueryTimeout = 3 
      validationInterval = 15000 
      testOnBorrow = true 
      testWhileIdle = true 
      testOnReturn = false 
      jdbcInterceptors = "ConnectionState" 
      defaultTransactionIsolation = java.sql.Connection.TRANSACTION_READ_COMMITTED 
     } 
    } 
} 

しかし、それはまだGrailsのでプールの問題の初期接続を作成することができませんでし示しています。私のGrails（プロキシはWiFiに接続する必要があります）でプロキシをクリアしました。私の上級代理店はGrailsの接続に影響します。リモートデータベースに接続できない理由を知りたい。

を使用していますが、ClassNotFoundExceptionが取得している：oracle.jdbc.driver.OracleDriverと

は、アプリケーションのクラスパスにあなたのojdbcXX.jarですか？あなたが使用しているオラクルのバージョンに応じて

（11のようです）あなただけのドライバパッケージ名を変更する必要があります：私が編集した後

driverClassName: 'oracle.jdbc.OracleDriver'
