spring 3とproxoolの統合について多くの人が質問しています

public class ProxoolInitListener implements ServletContextListener {
    private static final Logger logger = LoggerFactory.getLogger(ProxoolInitListener.class);

    @Override
    public void contextDestroyed(ServletContextEvent arg0) {
        // TODO Auto-generated method stub
        System.out.println("destroy database pool....");
    }

    @Override
    public void contextInitialized(ServletContextEvent contextEvent) {

        String appDir = contextEvent.getServletContext().getRealPath("/");

        try {
            PropertyConfigurator.configure(appDir + "/../conf/" + "proxool.properties");
        } catch (ProxoolException e) {
            logger.error("proxool init error:" + e);  //To change body of catch statement use File | Settings | File Templates.
            return;
        }
    }
}
