使用CalDav API集成雅虎日历

我正在尝试访问用户的雅虎日历，如果他的用户名和密码是已知的。我找到了一个使用CalDav API做代码的代码片段。代码使用2个库sardine.jar和ical4j.jar。该代码的文档说该代码将适用于谷歌日历和雅虎日历。只有我们必须相应地将URL更改为CalDav服务器。代码适用于谷歌日历罚款，但当我更改雅虎日历的代码，它不工作。我得到了以下错误：使用CalDav API集成雅虎日历

堆栈跟踪：]与根源 net.fortuna.ical4j.data.ParserException：错误位于第1行：预期[-3]，读[-1]

我想这是由于谷歌和雅虎ics文件格式不匹配或没有雅虎创建的ics文件。当我从浏览器使用这个URL时，我发现了谷歌日历的ics文件，但不是来自雅虎。

这是我使用的代码：

import java.io.BufferedReader; 
import java.io.IOException; 
import java.io.InputStream; 
import java.io.InputStreamReader; 
import java.util.Iterator; 
import java.util.List; 

import net.fortuna.ical4j.data.CalendarBuilder; 
import net.fortuna.ical4j.data.ParserException;

public static void main(String[] args) throws Exception { 

    Sardine sardine = SardineFactory.begin("Email","password"); 

    String url= "https://www.google.com/calendar/dav/[email protected]/events/"; 

    java.util.Calendar start = java.util.Calendar.getInstance(); 
    java.util.Calendar end = java.util.Calendar.getInstance(); 
    end.add(java.util.Calendar.MONTH, 1); 

    //Fri May 25 08:56:36 KST 2012==Mon Jun 25 08:56:36 KST 2012 

    Period period = new Period(new DateTime(start.getTime()),new DateTime(end.getTime())); 
    Filter filter = new Filter(new PeriodRule(period)); 


    //Collection<CalanderQueryOutput> results = new ArrayList<CalanderQueryOutput>(); 


    InputStream EventStream = sardine.get(url); 
    BufferedReader br = new BufferedReader(new InputStreamReader(EventStream)); 
    CalendarBuilder builder = new CalendarBuilder(); 
    Calendar calendar = builder.build(br); 


     List eventsToday = (List) filter.filter(calendar.getComponents(Component.VEVENT)); 
     CalanderQueryOutput caldavOutput = new CalanderQueryOutput(); 

    for (Iterator i = eventsToday.iterator(); i.hasNext();) { 

    Component component = (Component) i.next(); 


    String CreatedS = component.getProperty(Property.CREATED).toString().trim(); 
String SummaryS = component.getProperty(Property.SUMMARY).toString().trim(); 
String StatusS = component.getProperty(Property.STATUS).toString().trim(); 
String StartDateS = component.getProperty(Property.DTSTART).toString().trim(); 
String EndDateS = component.getProperty(Property.DTEND).toString().trim(); 

/*System.out.println(CreatedS); 
System.out.println(SummaryS); 
System.out.println(StatusS); 
System.out.println(StartDateS); 
System.out.println(EndDateS);*/ 
System.out.println(component); 


    } 
     }

请让我知道什么是worng与代码或如何获得雅虎日历编程ics文件。
