} You accomplish this using the CsvListReader.read() method果然也是很簡單

for(int j=0;j<header.length;j++){
System.out.println(header[j]);
}
UserBean user;
while( (user = inFile.read(UserBean.class, header, userProcessors)) != null) {
System.out.println(user.getZip());
}
List l;
while( (l = r.read()) !=null ){
System.out.println(l.get(0));
}

在基本的 HTML 網頁中，您可以使用 URL 來區別多個網頁檢視。 但是在 AJAX 應用程式中，向伺服器提出要求時並不會變更網頁的 URL，因此難以追蹤。
不過，您可以呼叫 _trackPageview 函數來為任何 AJAX 事件指派網頁檔名
pageTracker._trackPageview("/pagefilename1" );//pagefilename1可替換名稱 應該就可以了public interface TextProvider
Provides access to ResourceBundles and their underlying text messages. Implementing classes can delegate TextProviderSupport. Messages will be searched in multiple resource bundles, startinag with the one associated with this particular class (action in most cases), continuing to try the message bundle associated with each superclass as well. It will stop once a bundle is found that contains the given text. This gives a cascading style that allow global texts to be defined for an application base class.
super.getText("keyYouType")這樣就可以取出對應的值了!

}void open(string method, string url, boolean asynch, string username, string password)開啟對伺服端的連結；method為請求方式（GET、POST)；url是目標URL;asynch為非同步設定，預設是true。
void send(content)對伺服端傳送請求，content以放XML、輸入串流、字串、JSON格式的內容，放進去會放在POST本體中發送。void setRequestHeader(string header, string value)為HTTP請求設定一個給定的 header 設定值。
void abort()用來中斷請求。string getAllResponseHeaders()傳回一個字串，其中包含HTTP請求的所有回應標頭。string getResponseHeader(string header)傳回一個字串，其中包含指定的回應標頭值。
