JSP and JavaScript conversion date

I have a problem trying to convert a specific type of date.

My goal is to load it into this format: dd/MM/yyyy

Current Date Format: Thu Apr 04 00:00:00 EEST 2013

When I warn about using JavaScript, it replies that it is not a date. I used a lot of solutions, such as formatting in JSP:

 <fmt:formatDate value="${theDate}" pattern="dd/MM/yyyy"/>

Result Error:

 Attempt to convert String "Thu Apr 04 00:00:00 EEST 2013" to type "java.util.Date", but there is no PropertyEditor for that type.

And even in Javascript:

 var dateCreation = new Date(theDate);

The problem with JavaScript is that it says dateCreation not a date. Any ideas?

Problem with your date string "Thu Apr 04 00:00:00 EEST 2013"

when i tried with your date string to get IllegelArgumentException

change "Thu Apr 04 00:00:00 EEST 2013" to "Thu Apr 04 00:00:00 EST 2013" , then work fine.

I can not guess why you received this EEST (one E extra).

  public static void main(String[] args) { Date date = new Date("Thu Apr 04 00:00:00 EST 2013"); System.out.println(date); }

You get an error in javascript because you are passing the same JS string as me.

fmt: formatDate expects a java date object as a value. In your case, it looks like the Date object is not a date object, but a string representation of a date object. Specify a date object and this should work.

Also in JavaScript, what is the value of the param parameter and where is it defined?

The date object in JavaScript has the following constructors:

 var d = new Date(); var d = new Date(milliseconds); // from epoch var d = new Date(dateString); // "yyyy-mm-dd hh:mm:ss" var d = new Date(year, month, day, hours, minutes, seconds, milliseconds);

Make sure you use one of them. Keep in mind that the month for the last constructor mentioned is 0.

EST is GMT-05: 00, and EEST is GMT + 03: 00. The difference arises, for example. when parsing "Thu Apr 04 23:00:00 EEST 2013". Java (7) can parse EEST, but cannot format it in EEST.

  String s = "Thu Apr 04 23:00:00 EEST 2013"; SimpleDateFormat sdfParse = new SimpleDateFormat("E MMM d H:m:sz yyyy", Locale.ENGLISH); Date d = sdfParse.parse(s); SimpleTimeZone stz = new SimpleTimeZone(3 * 3600000 /* GMT+03:00 */, "EEST"); GregorianCalendar cal = new GregorianCalendar(stz, Locale.ENGLISH); cal.setTime(d); String ddmmyyyy = String.format("%02d/%02d/%4d", cal.get(Calendar.DAY_OF_MONTH), cal.get(Calendar.MONTH) + 1, cal.get(Calendar.YEAR)); System.out.println(s+"\n"+ddmmyyyy);

In JavaScript:

 function format2(s) {s="0"+s;return s.substr(s.length-2);} function dateFormat(theDate) { //theDate = "Thu Apr 04 00:00:00 EEST 2013"; var timestamp = Date.parse(theDate.replace(/EEST/, "GMT+0300")); var datePseudoGMT = new Date(timestamp+3 * 3600000); var dateCreation = format2(datePseudoGMT.getUTCDate()) +"/"+format2(datePseudoGMT.getUTCMonth()+1) +"/"+format2(datePseudoGMT.getUTCFullYear()); console.log(dateCreation); return dateCreation; }
