[root@ip-10-* webapps]# cp -r sourceDir/ /targetDir/ 
//将被复制到targetDir文件夹下 The SourceDir will be found under "targetDir"

2. Rename 重命名:

[root@ip-10-* 20100102update]# mv sourceDir/ newName

3. Move 移动:

mv Source.zip targetDir/

4. 移除整个目录:

[root@ip-10*webapps]# rm -rf Athena_Java/

在XAMPP中重置Mysql密码:

1. Go to http://localhost:port/security/  该链接将会对目前的配置进行安全检查

2. 该页面会检查当前安全配置, 并会带有链接: http://localhost/security/xamppsecurity.php

3. 该页面中可进行重置密码等操作.

选择Oracle, Next, 到如下界面:

Connect, 稍等片刻即可.

	resultSet.last(); // 游标移到最后, 获得rs长度
			int length = resultSet.getRow();
			resultSet.first(); // 还原游标到rs开头

2. 使用一个方法 Handle多个Alert.

// 弹出Alert
			Alert.show(RM.getString(BUNDLE_ONLINE_TEST, "olt.attempt.warn.remove"), RM.getString(BUNDLE_ONLINE_TEST, "olt.confirm.title"),
				Alert.YES|Alert.CANCEL, null, onAlertClose).data = "remove";
//----------------------统一响应---------------------------------

	// onWarning Close
	private function onAlertClose(e:CloseEvent):void {
		if((e.target as Alert).data == "remove") {
			if(e.detail == Alert.YES) {
			...
			}else {
				// do nothing
			}
		}else if((e.target as Alert).data == ALERT_ATTEMPT) {
			if(e.detail == Alert.YES) {
				...
			}
		}else if((e.target as Alert).data == ALERT_GO_ON_ATTEMPT) {
			if(e.detail == Alert.YES) {
				...
			}
		}else {
			throw new Error("无法识别的Alert关闭类型: " + e.toString());
		}
	}

原因: 执行的数据库查询没有查询到任何结果，却调用了resultSet.next().

2. java.sql.SQLException: 对只转发结果集的无效操作:

如果conn在创建时, 若不给定参数，预设是ResultSet.TYPE_FORWARD_ONLY、 ResultSet.CONCUR_READ_ONL, 此时不可进行游标操作, 会报错: java.sql.SQLException: 对只转发结果集的无效操作.
欲操作游标, 则应使用stmt=conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);

1. Vista, Win7没有特殊情况, 都要run as Admin

2. 元素命名:

Never Never Never 在工程中使用中文名的元素!
不要在元素命中使用".", 以往我在导入声音时, 如此命名: 1.1, 1.2, 1.3, 初次使用并无问题, 但再次打开或是复制后打开 发现会有很多copy of 1。… 此后声音完全乱了套

3. 慎重升级到5。 最近装了5， 但发现4的源文件到5的打开有若干问题, 如字体无法自动识别等.

4. 没事不要乱点, 也不要在导出或发布时"取消"

要进行解析的XML:

  
    13999910**
    
    me@liguoliang.mail
    [网络异常]服务器: {ID}网络异常
    
  

进行解析的PHP代码:

	/**
	 * 解析XML, 创建Site, 返回Site列表.
	 * @param $xmlPath
	 * @return unknown_type
	 */
	public static function loadSitesFormXML($xmlPath) {
		$xml = new DOMDocument(); // 创建DOM
		$xml->load($xmlPath);//'sites.xml'); // 加载XML
		$sitesXml = $xml->getElementsByTagName("site"); // 根据Name获得Elements列表.

		$arraySites = array();

		foreach($sitesXml as $site) { // 遍历每一个Element.
			$site = self::createSite($site); // 转入createSite()方法进一步解析DOMElement, 创建并返回Site对象.
			$arraySites[$site->id] = $site;
		}
		// logMesg("XML解析完毕, 共获得Stie对象: ".count($arraySites), false);
		return $arraySites;
	}

	/**
	 * 解析给定的DOMElement, 创建并返回Site对象.
	 * @param $site
	 * @return unknown_type
	 */
	public static function createSite(DOMElement $site) {
		$id = $site->getAttribute("id"); // 获得Attribute ID
		$url = $site->getAttribute("url"); // 获得Attribute URL
		$expectedReturnString = $site->getAttribute("expectedReturnString");
		$timeOut = $site->getAttribute("timeOut");
		$maxRetries = $site->getAttribute("maxRetries");
		$minErrorReportInterval = $site->getAttribute("minErrorReportInterval");

		$notifySmsToElement = $site->getElementsByTagName("notifySmsTo"); // 获得Element: 手机短信发送对象
		$notifySmsTo = $notifySmsToElement->item(0)->nodeValue;

		$notifySmsBodyElement = $site->getElementsByTagName("notifySmsBody");
		$notifySmsBody = $notifySmsBodyElement->item(0)->nodeValue;

		$notifyEmailToElement = $site->getElementsByTagName("notifyEmailTo");
		$notifyEmailTo = $notifyEmailToElement->item(0)->nodeValue;

		$notifyEmailSubjectElement = $site->getElementsByTagName("notifyEmailSubject");
		$notifyEmailSubject = $notifyEmailSubjectElement->item(0)->nodeValue;

		$notifyEmailBodyElement = $site->getElementsByTagName("notifyEmailBody");
		$notifyEmailBody = $notifyEmailBodyElement->item(0)->nodeValue;
		return $site = new Site($id, $url, $expectedReturnString, $timeOut, $maxRetries, $minErrorReportInterval, $notifySmsTo, $notifySmsBody, $notifyEmailTo, $notifyEmailSubject, $notifyEmailBody);
