I believe what is happening is that you are filling up your output buffer
and it auto flushes, then you try to do a redirect or forward and since the
buffer has been flushed, the response is implicitly committed. I ran into
this in a couple of places in my code, and could not move the forward up in
the page so I just increased the buffer size as follows and it works like a
champ:
<%
//THIS HAS TO BE DONE FIRST....DO NOT MOVE!!!!!!!!!!!!!!
response.setBufferSize(1024 * 15);
%>
As stated, this has to be done at the top of the JSP file. Obviously, the
more HTML and Client side script you have in your page before your
redirect/forward (which in the generated servlet becomes out.print(....))
the more likely you are to encounter this exception.
