Set headers with jsp

Question

hi,
i try to make a download page with jsp. here is my code:
<%@ page import="java.io.*,javax.servlet.*,java.util.* "%>
<%          
String filename = "super.zip";
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition","attachment; filename=\""+filename+"\"");
response.setHeader("Pragma","Public");
//is it correct to set headers like this
       FileInputStream fis = null;
       BufferedInputStream bis = null;
       ByteArrayOutputStream baos = null;
       int aux;     
       try
                 File f = new File("c:\\" + filename);
                 fis = new FileInputStream(f);
                 bis = new BufferedInputStream(fis);
                 baos = new ByteArrayOutputStream();
               while ((aux = bis.read())!=-1)
                    baos.write((byte)aux);
               baos.writeTo(response.getOutputStream()); //is it correct to return the content to browser like this     
       finally
               if (bis != null)
                    bis.close();     
%>and the error i get is
getOutputStream() has already been called for this response
i need immediate help. i hope someone knows the answer. thanks...

The issue is that you can not have PrintWriter and OutputStream at
the same time.
