Sorry for late respose.
This is how I did:
- Create a Template Class extends
WOComponent.
- put in the stefan's code in AppendToResponse
accordingly, including _asStream method
- create a action button in the caller component
such as:
public Template downloadAction()
{
//for
testing only, otherwise should use its class name to replace
"Template"
Template nextPage =
(Template)pageWithName("Template");
//
Initialize your component here
return
nextPage;
}
- do test and the action button should trigger the
download.
This is just a brief one and i believe more details
could be found in WebObjects file downloading sample code.
Cheers

Hi Fred
That is where I am trying to recall - is it due to when you zip all
directory of files and after that it was unable to continue when the file size
reaches ~30M. The number 30M is quite a familiar number to me :) b'cos
it hit me many times before.
I have also
tried out Stefan's code and it worked fine. I suggest you could look at
the code how you keep all the files zip together before calling
setContentStream.
Just4c
now..

Simon, Cheong, Anjo
thanks.
So I was able to get it to work after pushing the send/recieve
timeout up. So in my attempts to get this to work I was using
WOLongResponsePage and it still failed. So was I using that wrong? I created a
component that was a subclass of WOLongResponse page and performed my actions
in appendToResponse. That included zipping up a directory of files and then
passing the stream of that zip to the content stream. Or did I need a
combination of both [WOLongResponse and adjusting the send/recieve timeout] to
get this to work?
