Problem in viewing PDF File.

Question

Hi All,
I created a servlet which reads the PDF file from the file system and to show it in the browser. And I attached the URL in my HTML Page. Whenever I click on that URL it is activating PDF viewer in the browser and browser is showing the blank page. But, The moment I refresh the page I was able to view the PDF document. I am sure this is not a coding problem. It looks like some problem with the plug-in. I tried by reinstalling the Acrobat Reader 5.0 still I am facing the same problem. I am using Windows2000 Professional, SilverStream 3.7.is the application Server. Database is Oracle 8i.
I want to avoid the second step(i.e refresing the page to view PDF document). Can any one help me out in this matter.
Thanks in advance for helping me out in this problem.
Thanks
Shivaji

I've been working on displaying pdf from a servlet, and although I don't know exactly what your situation is, here is how I served up the pdf file from the servlet using the HttpServletResponse object.
            byte[] data = getFileBytes();// from somewhere
            response.setContentType("application/pdf");
            response.setContentLength(data.length);
            java.text.SimpleDateFormat dateFormat = new java.text.SimpleDateFormat("EEE, dd MMM yyyy - HH:mm:ss z");
            response.setHeader("Expires", dateFormat.format(new java.util.Date()));
            response.getOutputStream().write(data); //Write out the pdf report
            response.getOutputStream().flush(); //flush the buffer
