Topic awaiting preservation: Create .ics file

I was trying to create a .ics icalender file when user click on a link.

How could I in JSP parsed a few parameters and a file could be created?

In ASP, this could be accomplished using:

Response.ContentType = "text/x-vCalendar"

Response.AddHeader "Content-Disposition", _ "filename=Event.vcs;"

Response.Write starvCalendar

Response.End

I have also seen a much simplier example:

<FORM method="post" name="vCalendar" action="http://www.cvent.com/EventManagement/Summary/eventInfo.ics">

<input type="hidden" name="planner" value="boston@yahoo.com">

<input type="hidden" name="title" value="Weekly Email - December 12, 2000">

<input type="hidden" name="start" value="20011215T010000Z">

<input type="hidden" name="end" value="20011215T030000Z">

<input type="hidden" name="loc" value="Caprice Club">

<input type="hidden" name="desc" value="Description bla bla bla ">

<input type="hidden" name="createdate" value="20010822T014533Z">



Friday, December 14, 2001 8:00 PM - 10:00 PM&nbsp;<a class=detailsLinks href="javascript:document.vCalendar.submit();">Add to my calendar</a>



</FORM>

My question is I am not sure about the line

<FORM method="post" name="vCalendar" action="http://www.cvent.com/EventManagement/Summary/eventInfo.ics">

if I create a similar file in my local directory, the entire code doesn't seem to work at all. I am very confused. I appreciate any assistance.

Thank you again.

I'm pretty sure that that form posts to an url that's internally redirected to some kind of scripting language (or cgi). Kinda like it's done in this place (look at the ->rssChanges for an example).

Sorry, but I can't help you with JSP, I haven't worked with it yet.

The poster has demanded we remove all his contributions, less he takes legal action.
We have done so.
Now Tyberius Prime expects him to start complaining that we removed his 'free speech' since this message will replace all of his posts, past and future.
Don't follow his example - seek real life help first.

Ini,

Have you done anything with regards to create an icalendar file? Thank you.

Ini,

I have not done anything yet as I am still trying to learn how to do this.

What I have found so far is if I have the parameter in the form (above) parsed into a Bean and the bean return a streams of strings into the browser then the MIME should pick it up. I have a javascript version which some one has kindly posted in the internet, but I do hope to have it in Java Bean.

Would you be able to assit me further in this?

Thanks Ini.

I have learn the iCalander format. I reckon my current missing link is to learn how to do some basic I/O from a Java Bean or JSP so that the iCalendar Text file is created once someone click on "Add to my Calendar" in the form which I posted earlier.

I/O is something which I have not attempted at all. but will give it a good try.

Thanks.

Ini,

I am getting a bit confused after reading on some material and some simple test. I understand that the string which I need to to sent to a browser is :

BEGIN:VCALENDAR

So I did a quick test with this JSP file:

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

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

<%

response.setContentType("text/x-vCalendar");

response.setHeader("Content-Disposition","filename=event.ics");

%>

<% response.close %>

Somehow, it just print on the browser and does not involke outlook client.

Most of the example which I have come across involve a .ics file. Is this necessary as I understand you could also write to browser directly?

Thank you again.

Ini,

What do you mean the "link to the output page"? I access the page directly from browser. ie
http://servername/test/icalendar.jsp

The source code of the output is in my previous posting.

One of the interesting article which I have found is this:

http://www.devx.com/getHelpOn/10MinuteSolution/20508

It's doing almost the same thing (only in ASP).

I greatly appreciate your assistance on this issue. Thanks again.

Ini,

The following works now. It also works with attachment in the setHeader. The following will prompt for user to "Open" or "Save". Do you know if that is a way to force it to Open and not Save?

Thank you.

<%

response.setContentType("text/calendar");

response.setHeader("Content-Disposition","inline;filename=event.ics");
