streaming files with wicket

[Douglas Ferguson <do...@douglasferguson.us>]

I built a page with markup type = xml and set the content type and disposition so that the file will download.

This is great except when there is a fatal exception thrown, my error page is getting written to the downloaded file.

Any ideas how make the browser load the error page?

Only thought I had was to stream the file to disc and then send A) stream to browser if there is no exception or B) forward to error page.
But that kinda sucks as it is not truing streaming back to browser.

Igor's response doesn't mention hitting disk.
You can do it in memory

Yeah.. I thought of that, but I liked the idea of streaming without hitting
disc.

i dont think there is a way once you start streaming with an
attachment header...

you can try rendering the page into memory and writing that out
instead - so then you at least know your page rendered ok.
