i converted download servlet to jsp, and... exception occurred -"You already got writer." here is my jsp code.. <%@ page errorPage="error.jsp" %> <% String file = request.getParameter("p_file"); byte b[] = new byte[1024]; File file=new File(pp_file); FileInputStream fin=new FileInputStream(file); response.setContentType("application/octet-stream"); response.setHeader("Content-Disposition","attachment;filename=" + pp_file + ";"); ServletOutputStream dataOut = response.getOutputStream(); // maybe, this line caused problem. int numRead = fin.read(b); while (numRead != -1) { dataOut.write(b,0,numRead); numRead=fin.read(b); } dataOut.close(); %> so i tried to use out instead dataOut ..like this.. response.setContentType("application/octet-stream"); response.setHeader("Content-Disposition","attachment;filename=" + pp_file + ";"); int numRead = fin.read(b); while (numRead != -1) { out.write(b,0,numRead); numRead=fin.read(b); } at this time, content of file just displayed on browser.. how can i solve these problems ? anybody knows ? =========================================================================== To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".
