Subject line feeds in response
Date Mon, 09 Sep 2002 15:43:46 GMT
Hi all,

got the following problem:

I'm generating xml with jsps. Before I write out any response, I'm using
out.clearBuffer() to
clear anything from the output buffer in order not to write out new lines
etc.
However, this doesn't seem to work. I always get 3 line feeds before the xml
starts, which
causes most parsers to fail parsing that xml.
I was wondering wether this is caused by the dispatcher mechanism I'm using:

RequestDispatcher dispatcher = request.getRequestDispatcher(jspUrl);
dispatcher.forward(request,response);

since the resulting servlet code for the jsp begins output without any line
feeds, so this problem can't have it's origin the jsp. The generated source
code is:

// begin [file="/includeHeader.jsp";from=(0,2);to=(0,15)]
   out.clearBuffer();
// end
// HTML // begin [file="/includeHeader.jsp";from=(0,17);to=(1,0)]
   out.write("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n");

I tried to use also the clear() method in the out object, also reset(),
resetBuffer() in HttpServletResponse,
with the same results. The line feeds are always outputted before the "<?xml
version=\"1.0\" encoding=\"UTF-8\"?>\n" String.

I'm running jakarta-tomcat-4.0.4-LE-jdk14 on nt 4.0.

Any help would be really, really appreciated.

Thanks

Alex
