Fred
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..
Cheers

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?
