Re: Getting the date/time from the client

2006-07-11 Thread Shinya Koizumi 

One is to embed javascript in the output

out.println(HTMLHEADtitleJavaScriptExample/title);
out.println(SCRIPT LANGUAGE=JavaScript);
out.println(function back() {);
out.println(history.back(-1););
out.println(});
out.println(/SCRIPT);
out.println(/HEAD);


The other solution is to get it from the request header.

protected void doGet(HttpServletRequest request, HttpServletResponse 
response)

throws ServletException, IOException {
long l = request.getDateHeader(Date);
Date d = new Date(l);
System.out.println(d);
}

Hi All,

I am doing a project in jsp/servlet and tomcat, which requires to take
the client date/time (ie the time of the machine the browser is
running). Is there any way to accomplish this ?

Thanks  regards

Hi,

May be you can use:
request.getDateHeader()

Have a look at, there is a related thread there:

Yeah, you are right about it, I can't get getDateHeader working.

For the solution one, I have setup like this for jsp and worked.

Re: Getting the date/time from the client

2006-07-11 Thread Vinu Varghese 

SK,
That javascript prints the current client time. But I want the client 
time with the request.

The scenario is :

I have a index.jsp

%@ page language=java contentType=text/html; charset=ISO-8859-1
   pageEncoding=ISO-8859-1%
!DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.01 Transitional//EN
html
head
meta http-equiv=Content-Type content=text/html; charset=ISO-8859-1
titleInsert title here/title
/head
body
Client time : a href=clienttime.htm Click/a
/body
/html

and  a servlet that can take the client time (Hoping to :-) ) which is 
mapped to 'clienttime.htm'


   protected void doGet(HttpServletRequest request, HttpServletResponse 
response) throws ServletException, IOException {
  
   response.setContentType(text/plain);
  
   long time = request.getDateHeader(Date); // Hoping to get the 
client date.
  
   PrintWriter out = response.getWriter();
 
   out.println(Server time  + new Date());
  
   out.println(Client time (long)  + time);
  
   out.println(Client time  + new Date(time));
  
   }



Is there any way to do this (get the client time from the request) ? 


Or Am I trying to do a dumb thing ? ;)

Re: Getting the date/time from the client

2006-07-11 Thread Shinya Koizumi 

uh...
no luck yet. getDateHeader only returns the date value when
you have some query strings in date format.
So, send the time as a part of query string like this
index.jsp?requesttime=25:40:12 or something similar.

If one has a better solution let him know.

Re: Getting the date/time from the client

2006-07-11 Thread Jon Wingfield 
The HTTP spec (rfc2616) says clients should only send the Date header 
with http messages with body content (POST, PUT) and even then it's 
optional.


Try adding a date string as a parameter on your GET request which your 
servlet can then parse from request.getParameter(...).


One way to do this would be to change your link to a form with a hidden 
input field for your date value. Add an onclick/onsubmit javascript 
handler to your form button which sets the value of the hidden field to 
the current date in a format that your servlet will understand.


for example:

function setDate(form) {
  form.dateField.value = new Date().toString();
}


Example assumes a hidden form input field with name dateField.

Jon

Subject: Getting the date/time from the client


   


Hi All,

I am doing a project in jsp/servlet and tomcat, which requires to
take
the client date/time (ie the time of the machine the browser is
running). Is there any way to accomplish this ?

Thanks  regards
Vinu

Is that really appropriate??  What if I have my Locale set to France, and my
clock set to Pacific Standard Time?  Then what?  (assume I am on the east
coast of the USA...)

 hidden

  the current date in a format that your servlet will understand.
 
  for example:
 
  function setDate(form) {
form.dateField.value = new Date().toString();

  The scenario is :

  Client time : a href=clienttime.htm Click/a

  and  a servlet that can take the client time (Hoping to :-) ) which
 is
  mapped to 'clienttime.htm'
 
 protected void doGet(HttpServletRequest request,
  HttpServletResponse response) throws ServletException, IOException {
   response.setContentType(text/plain);
   long time = request.getDateHeader(Date); // Hoping to
  get the client date.
   PrintWriter out = response.getWriter();
  out.println(Server time  + new Date());
   out.println(Client time (long)  + time);
   out.println(Client time  + new Date(time));
   }
 
 
  Is there any way to do this (get the client time from the request) ?
  Or Am I trying to do a dumb thing ? ;)

A good devil's advocate question, or was it rhetorical?

Either way it's got exactly the answer you'd expect, you'll set the date
to whatever Locale the Request returns.  Obviously.

I was playing devil's advocate -- since we don't really know the OP's
