How Ajax decides, which response it will set to responseXML and which to responseText.
			

			

			private void writeResponse(HttpServletResponse resp, String output) throws IOException {
			

			resp.setContentType("text/xml");
			

			resp.setHeader("Cache-Control", "no-cache");
			

			//resp.getWriter().write(output);
			

			PrintWriter out = resp.getWriter();
			

			out.write(output);
			

			//out.println(output);
			

			//out.flush();
			

			}
			

			

			if I use the above function in my servlet, I don't get the responseText, but if I  use the following function I get responseText.
			

			

			private void writeResponse(HttpServletResponse resp, String output) throws IOException {
			

			resp.setContentType("text/xml");
			

			resp.setHeader("Cache-Control", "no-cache");
			

			//resp.getWriter().write(output);
			

			PrintWriter out = resp.getWriter();
			

			//out.write(output);
			

			out.println(output);
			

			out.flush();
			

			}
			

			

			Please clarify.
