If this is Wicket 1.2.6, yes I can understand this issue, and it's
fixed in 1.3. It was a bug in BufferedWebResponse, not buffering
enough.
Back to your problem: does it work on Tomcat or Jetty?
Note that for security reasons you shouldn't mention the absolute
path in the URL. I advise to prepend the root path in the code.
Also be careful of the double slash! By reading your code, the
request translates to:
reports//path/to/file
