respond() { ... r.setattachmentheader(..); r.setContentType(..) super.respond(); }
or do how i showed you in the first place using an anonymous imple of IRequestTarget directly.
IRequestTarget.detach() { } IRequestTarget.getLock() { return null; }

I'd like to do it the clean way... When I do this:RequestCycle.get().setRequestTarget(new StringRequestTarget("hello"){
public void respond(){
String txt = "content";
WebResponse r=(WebResponse) WebRequestCycle.get().getResponse();
r.setAttachmentHeader(filename);
r.setContentType(contentType);
try {
Streams.copy(new StringInputStream(txt), r.getOutputStream() );
} catch (IOException ex) {
ex.printStackTrace();

});The content shows up as "hello" and opens in the browser not as the correct content type, I'm sure I'm using the wrong kind of IRequestTarget, which one should I use? I can't figure out the syntax for EmptyRequestTarget and still override respond().J

Subject: Re: [Wicket-user] Downloading a file generated on the flywhile this works it is a bit hacky. it would be better to let the requesttarget's response method produce the output.

Subject: Re: [Wicket-user] Downloading a file generated on the fly
Here's an application that I wrote.
The application retrieves data from a database and converts it to an Excel XLS file.
I am sending the XLS file to the web browser via the ServletOutputStream.
Note: DatabaseQueryForm extends BaseForm

I am thinking that I can do something similar but extend DynamicWebResource. Then use ResourceLink to link to it... Would this work? Is there a better way to do it?J
