java.lang.IllegalStateException: getOutputStream()

When I open an email attachment, it works fine, but
then I get this error, if I click twice on the
hyperlink to the attachment. Obviously, this is a
webmail application.

Re: java.lang.IllegalStateException: getOutputStream()

Posted by Luminous Heart <lu...@yahoo.com>.

I found out that the servlet specs requires that we
use getWriter instead of getOutputStream(). I guess it
is more effecient to use PrintWriter and getWriter
instead of my approach. 

Hope that will be helpful.
