Hi Jaisamma,

let me know , what u mean with this ID?.

In JSP , you have two options,

1) You can use javascript to find out the Current date and format it.

2) You can use java code itself to find out current days date and format it.

In JSP

Using javascript

-

<b><html>

<script language="javascript">

function onLoadin()

{

d = new Date();

var date = d.getDate();//For getting date range 1-31

var month = d.getMonth()+1;//Value range 0-11

var year = d.getYear();

/*

for formatting it to presentable format

*/

var sydate = date + "/" + month + "/" +year;

document.myForm.datum.value= sydate;

}

</script>

<body onLoad="onLoadin()">

<form name="myForm">

<input name="datum" type="text" size="13" maxlength="10"/>

</form>

</body>

</html>

go through this.

http://www.javascriptkit.com/jsref/date.shtml

</b>

this contains details of javascript date object

http://www.w3schools.com/jsref/jsref_obj_date.asp

Using java code

-

<%@ page import="java.text.*" %>

<%@ page import="java.util.*" %>

<%

Format formater = new SimpleDateFormat("dd/MM/yyyy");

Date syDatum = new Date();

<td><font SIZE="1">Date</FONT></td>

<td align="left"><i><%=formater.format(syDatum)%></i></td>

%>

let me know , is your application using any database for storing the ID ?.

hi,

the bellow piece of code should work for u..

<script type="text/javascript">

<%Date now = new Date()%>

document.form[0].datum.value=

<%=DateFormat.getDateInstance().format(now))%>

</script>

Since the Date method is of java's ,you have to place them in scriptlet and when it reaches the browser (<%=... %>) is replaced with the actual date value..

Regarding the ID , the best way is to generate the id from the database. If u want to avoid using database and still want to create id's dynamically , i can suggest some methods(which may not be fool proof.).

Hai jaisamma,

for what purpose r u using this IDs?

r u storing this IDs in any data base?.

r u reusing this IDs in future or just for one time display?.

if u r using this for one time purpose , then we can take the current time inmillis . its unique.. but for later use u have to store it somewhere.

Hi Jaisamma ,

one simple way to generte id is , u can take the

System.currentTimeMillis()).toString() method to get the current time in millis . it will be unique always.(but u have to give proper data lenght for storing this.

another way is , u can get the max value from the data base itself for particular column.

SELECT MAX(<ID>) FROM <table Name>.

Edited.

-

that depend upon the database.

u can use long ..

just hav a look at this
