how to integrate jquery calendar with jsp

Answer 1

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);

Answer 2

I've created a servlet and am able to generate JSON script. I'm not sure how to feed the JSON response in fullcalendar. I've tried using the servlet URL. But it didn't help. Kindly help me with a sample code.

Answer 3

It Work with servlet this is how:

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 -- Ghazi
    json = "[" + json + "]";***

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