	protected final Log logger = LogFactory.getLog(getClass());
	
	public void insertLog(String num, String nature, RenderRequest request)
	{

			String mail = UserLocalServiceUtil.getUserById(
					Long.parseLong(request.getRemoteUser())).getEmailAddress();
			String ip= UserLocalServiceUtil.getUserById(
					Long.parseLong(request.getRemoteUser())).getLoginIP();
			

			logger.info("request à faire : execute PMT_LOG_INSERT_01('216"+num+"',"+nature+",'"+mail+"',182,'"+ip+"')");
			
        getSimpleJdbcTemplate().update("execute PMT_LOG_INSERT_01('"+num+"',"+nature+",'"+mail+"',182,'"+ip+"') ",
