RE: Two problems: Struts2 + https + file load and Struts2 + file load + java.lang.IllegalStateException: getOutputStream()

[UncleLongHair <un...@tidd.cc>]

I was getting the "getOutputStream() has already been called for this
response" problem and figured out a solution.  In my case, I was able to
switch from getOutputStream() to getWriter() because I was dealing with text
files, and the error message stopped.

I think the error message is misleading, I think you can get it if either
getOutputStream() gets called more than once OR if both getOutputStream()
and getWriter() are called.  I wonder if the idea is to prevent both text
and binary data from being written into a response.

I understand that this might not help everyone, but I thought I'd offer it
up.  It might be worthwhile to look at the source for HttpServletResponse to
see the conditions under which the error is thrown.
