How do I convert a string to an iCalendar(ics) object?

Question

I have been given the task of implementing a way to convert a string received through a JSON object to an iCalendar object(ics). I found the iCal4j library and have been attempting to use that as my parser. however it seems that the CalendarBuilder takes an InputStream.

How do I proceed ?

String response = jsonObj.getString("icalendar");

CalendarBuilder calBuiler = new CalendarBuilder();
Calendar calendar = calBuilder.build("???");
....

Edit : Would this work?

public Calendar convertStringtoCalendar(String arg)
{
    CalendarBuilder calBuiler = new CalendarBuilder();
    InputStream is;
    try {
        is = new ByteArrayInputStream(arg.getBytes("UTF-8"));
        return calBuiler.build(is);

    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (ParserException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return null;
}

Solved the problem by doing the following.

public static Component getCalendarEvent(String myCalendarString) 
{
    try {
        StringReader sin = new StringReader(myCalendarString);
        CalendarBuilder builder = new CalendarBuilder();
        Calendar calendar = builder.build(sin);

        return (Component)calendar.getComponent("VEVENT");

    } catch (Exception e) {e.printStackTrace();}

    return null;
}

I suggest you try my new iCalendar API for Java called iCalendarFx. It can parse a string into any calendar element - VCALENDAR, VEVENT, etc.
