Flex pdf request to PDF response creation logic

This code is to get the pdf request from Flex application and generate pdf file which will be displayed in the flex application.

@Override
public void doGet(HttpServletRequest req, HttpServletResponse resp)
  throws ServletException, IOException {


 System.out.println("I am in pdf Exporter get method");
 int maxLength = req.getContentLength();

 String method = req.getParameter("method");
 String name = req.getParameter("name");

 ServletInputStream si = req.getInputStream();

 ServletOutputStream stream = resp.getOutputStream();

 resp.setContentType("application/pdf");
 resp.setContentLength(maxLength);
 resp.setHeader("Content-Disposition", method + ";filename=" + name);

 copyStreams(si, stream, 100);

 stream.close();
}


//read the input stream and copy in to output steam
//Input stream will have pdf content which is coming from flex application
private void copyStreams(InputStream inStream, OutputStream outStream, int flushCount) throws IOException
{
 int currentByte;
 int flushCounter = 0;

 while((currentByte = inStream.read()) != -1)
 {
  outStream.write(currentByte);
  if(flushCounter++ > flushCount)
  {
   outStream.flush();
   flushCounter = 0;
  }
 }

 outStream.flush();
}
