LinuxMandrivaにTomcat7MySQLデータベースをインストールしましたが、アプリケーションがコンテナーにデプロイされているため、接続できません。

私は2つの簡単なテストを作成し、クライアントからそれらを実行すると、接続を取得します-

public class TestHibernate {
    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        User user = new User();
        user.setName("userName");
        user.setPassword("userPassword");

        Session session = HibernateUtil.
            getSessionFactory().openSession();

        session.beginTransaction();
        session.save(user);
        session.getTransaction().commit();

        session.close();
    }
}

HibernateUtilの一部-

...
      cnf.setProperty("hibernate.connection.url", "jdbc:mysql://ip:3306/gibrid");
      cnf.setProperty("hibernate.connection.username", "java");
      cnf.setProperty("hibernate.connection.password", "java");
...

Jdbcテスト-

public class TestJdbc {
    public static void main(String[] args) {
      Connection conn = null;
      String url = "jdbc:mysql://ip:3306/";
      String dbName = "gibrid";
      String driver = "com.mysql.jdbc.Driver";
      String userName = "java"; 
      String password = "java";
      try {
          Class.forName(driver).newInstance();
          conn = DriverManager.getConnection(url+dbName,userName,password);
          System.out.println("Connected to the database");
          conn.close();
          System.out.println("Disconnected from database");
      } catch (Exception e) {
          e.printStackTrace();
    }
  }
}

このような場合、接続を取得してデータベースを操作できます。しかし、クライアントブラウザからリクエストすると、タイムアウトが発生します。何故ですか?情報をいただければ幸いです。


これがcatalina.outです-

私は Hibernate に詳しくないので、これが関連しているかどうかはわかりません:

「hibernate.properties が見つかりません」

「使用するドライバー: com.mysql.jdbc.Driver at URL: jdbc:mysql://---ip here----/gibrid」

IPポートはテスト プログラムと同じですか?

このブログは、C3PO の構成の問題を示唆しています。1 つのコメントは、Mysql と C3PO の間の異なるタイムアウト設定を示唆しています。HTH
