That looks like an excellent API. Would it be very hard to implement this? Personally I am also looking for something like this, but then bookmarkable. I got some suggestions on how to do this with the current APIs, but I did not like them at all. So now I am using a servlet. Regards,

That is exactly what I am looking for. Perhaps someone could show a sample of implementation or even better to make it in the release? Sorry if there was any misunderstanding of my question but this is something Wicket should excel against other frameworks. That looks like an excellent API.

Never mind. I just saw and tested Johan Campagner's posted solution and it resolves all issues. This is why I like Wicket and its developers. That is exactly what I am looking for. Perhaps someone could show a sample of implementation or even better to make it in the release? Sorry if there was

This does not apply as it copies input to output. My issue is that in OnClick() I call excelGen(OutputStream) to produce the bytes on the fly. but the ResourceStream needs InputStream that wicket would read data to send as response. My take is that I need to get a handle of the reponse

is it really that difficult to do some legwork? the hint in downloadlink is to do getrequestcycle().setrequesttarget(new irequesttarget() {..}); irequesttarget has a respond(requestcycle cycle); cycle in turn has a cycle.getresponse().getoutputstream(). -igor On Tue, Apr 1, 2008 at 12:59 AM,

In a raw servlet programming, it is trivial, just get response outputstream, set headers and pass it to the excelGen (as a poorman's way, close the connection after done) Wicket got to have a more structured api for this common task. This one (even with model args) falls to the same category of

Well, if you're using WicketFilter, then you can just write your own servlet. If WicketFilter doesn't think it's responsible for the request, it'll let it flow through. So, you could just code this using Servlets anyway. Wouldn't extending WebResource and using ResourceLink be the way to do

I think he makes a valid point, personally. People do want to do this sort of thing quite frequently. It wouldn't kill us to implement an OutputStreamLink that looked like this: add(new StreamingLink(link) { public String getFileName() { return download.xls; } public String
