111, 'title' => "Event1", 'start' => "$year-$month-10", 'url' => "http://yaho开发者_运维知识库o.com/" ) )); ?>

You need to create a Servlet for that. Create a class which extends HttpServlet and write code in doGet() accordingly that it writes the desired JSON string to the response. You can use Google Gson to convert Java objects to a JSON string.

For example:

// Gather data.
Map<String, Object> map = new HashMap<String, Object>();
map.put("id", 111);
map.put("title", "event1");
map.put("start", new SimpleDateFormat("yyyy-MM-10").format(new Date()));
map.put("url", "http://yahoo.com/");

// Convert to JSON string.
String json = new Gson().toJson(map);

// Write JSON string.
response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
response.getWriter().write(json);

Then just map this servlet in web.xml on the desired url-pattern.

Instead of a Map you could even create your Javabean class Event:

public class Event {
    private Long id;
    private String title;
    private Date start;
    private URL url;
    // Add/generate getters/setters.
}

You could even use Gson to convert it:

Event event = eventDAO.find(request.getParameter("id"));
String json = new Gson().toJson(event);

This way you can more easy collect them all in a List<Event> which is preferable above a List<Map<String, String>>:

List<Event> events = eventDAO.list();
String json = new Gson().toJson(events);

In your servlet put this script:

map.put("id", 111);
map.put("title", "event1");
map.put("start", new SimpleDateFormat("yyyy-MM-10").format(new Date()));
map.put("url", "http://yahoo.com/");

// Convert to JSON string.
String json = new Gson().toJson(map);

// Put json between [] to be formatted by Fullcalendar
json = "[" + json + "]";

// Write JSON string.
response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
response.getWriter().write(json);

First you need to invoke the servlet from jQuery - you do this with $.ajax(). Then you need to pass the result to the calendar. The following works fine:

$.ajax({
          url: 'app',
          dataType: "json",
          success: function(response) {
              $('#calendar').fullCalendar({
                  header: {
                        left: 'prev,next today',
                        center: 'title',
                        right: 'month,agendaWeek,agendaDay'
                    },
                    editable: true,
                    events: [response]
                });
          }
        });
