Use SimpleDateForma tter and GregorianCalend ar class in your JSP file to convert the date you got from javascript into your database format.

thank you for your time..my problem actually is to load the event from the database to the jquery calendar..my database is mysql

It's the same way. It's just the problem of converting one string into another.
Whether from database to calender format or from calender to database format, it doesn't matter.

When you got your date from the database via jdbc-SQL, it has a special format (by default yyyy-mm-dd in mySql, unless you have saved it in some other format or converted it by SQL directly). Your task is to convert this String into an another String that your javascript calender needs (json format).

You could do it manually with string manipulations, like splitting at delimiters and home-made parsing. But this would lead to a complicated and error-prone function. So use GregorianCalend er and SimpleDateForma tter, they are your friends and will ease this job a lot.

So instead of converting
String --> (via home-made function) --> String,
you convert
String -->(via SimpledateForma tter) --> GregorianCalend ar Object --> (via SimpleDateForma tter) --> String

(Remark:As an equivalent to the PHP-code above you could also use the Date object instead of GregorianCalend ar, but that's deprecated.)

thank chaarmann for your explaination..m y problem is not how to convert the date but how to encode json in java especially in jsp..as you can see in the code example,it encode the json in php..my major problem is here

# echo json_encode(arr ay(
#
# array(
# 'id' => 111,
# 'title' => "Event1",
# 'start' => "$year-$month-10",
# 'url' => "http://yahoo.com/"
# )
#
# ));

It seems your major problem is that you don't understand the JSON format.
I didn't understand, too.
But I googled "JSON" and one of the top links is "http://en.wikipedia.or g/wiki/JSON"
and there is written in the middle of the page as an example:

{
     "firstName": "John",
     "lastName": "Smith",
     "address": {
         "streetAddress": "21 2nd Street",
         "city": "New York",
         "state": "NY",
         "postalCode": 10021
     },
...

So looking at that it seems pretty easy:
Array is a curly bracket "{" instead of "array(" in PHP,
keys and values are separated by ":" instead of "=>".

So you must convert your code

array(
 'id' => 111,
 'title' => "Event1",
...

into

{
 "id" : 111,
 "title" : "Event1",
...

That means you must put that into a String and pass it to javascript:

String json="{\"id\":111, \"title\":\"Event1\", ...";

To fill in the values from database for "$year" and "$month", just use the SimpledateForma tter as I described before. I hope you understand now better that it's just a simple string to string conversion, from one format to another.
