Downloading the generatred PDF from the server results in a blank browser

Question

Hi,
We are using iText to generate PDF documents and that's working fine. Only when we try downloading the generated PDF document it just opens up a blank browser and does not display anything. This behavior is noted in IE and Firefox! The application is hosted on IBM Websphere and IBM Web server on a Linux machine, the application is a https (secured) application.
There are no errors logged in the log, just that the PDF does not get downloaded. The size of the PDF files are around 2.5 MB.
When I try to replicate the issue from my local workspace the same PDFs work fine - able to download! Any app ser/web server setting issue? Has anyone faced such an issue, any suggestions?
Thanks

Hello All,
Thank you for initiating to reply. Actually the case is erratic, as I said in my first post, as the document gets downloaded for a few times and does not for a few times. The pattern is whenever the file size if 2.5 MB or more then the doc. does not get downloaded on the client side (browser - IE & firefox). Below is the code (it has the proper content type, content disposition), please have a look at this and suggest
     String fileName = pdfName+".pdf";
          File file = new File(outputPdfFolder+ fileName);
          BufferedInputStream input = null;
          BufferedOutputStream output = null;
          try {
          response.setContentType("application/pdf");
response.setHeader("Content-Length",""+file.length());
response.setHeader("Content-Disposition", "inline;filename=\""+outputPdfFolder+fileName+"\"");
// Open streams.
     input = new BufferedInputStream(new FileInputStream(outputPdfFolder+fileName), (int)file.length());
output = new BufferedOutputStream(response.getOutputStream(), (int)file.length());
logger.logInfo(this,"File length size:"+file.length());
long fileLength = file.length();
byte[] buffer;
if(fileLength < Integer.MAX_VALUE) // this constant value holds the MAXIMUM POSSIBLE VALUE of integer data type
buffer = new byte[(int)fileLength];
input.read(buffer);
output.write(buffer);
else
          buffer = new byte[1000];
          int c;
     while ((c=input.read(buffer, 0, 1000)) != -1)
     output.write(buffer, 0, c);
          }
