java – 我是否正确关闭了这个Oracle池连接？

public class DatabaseHandler
{

    static private Connection m_database = null;

    static private OracleConnectionPoolDataSource pooledSource = null;

    static public void openDatabase(String userName,String password,String serverName,int portNumber,String sid)
    throws WebApplicationException
    {
        try
        {
            // Load the JDBC driver
            String driverName = "oracle.jdbc.driver.OracleDriver";
            Class.forName(driverName);

            // Create a connection to the database
            String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid;

        }

        {
            throw new WebApplicationException(Response.Status.INTERNAL_SERVER_ERROR);
        }
    }
}

我在Eclipse中这样做,我发出警告,pooledSource.close()已被弃用.我以前从未使用过汇集连接,我只是想确保我正在做的一切正确.有没有更好的方法来关闭Oracle池化资源？
