Hi,
Servlet specs do not allows to write both to the servletresponse's
outputstream and its writer.
In your code you write to the stream and later somewhere else (maybe
Wicket) writes to the writer.
See the code in DownloadLink to see how it writes the file bytes.
You cannot write your OpenID response together with Wicket page response.
