Problem opening servlet generated PDF in browser

Question

This is the code i use to show the PDF in a browser
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
res.setContentType("application/pdf");
res.setHeader("Content-Disposition","inline;Filename= " + file.getName());
ServletOutputStream sos = res.getOutputStream();
               outStream.writeTo(sos);
               sos.flush();          
               outStream.close();
               sos.close();
In Netscape i get an error saying the filename does not start with %PDF and in IE the page just shows up blank. from the blank pagewhen i use the back button and then hit the forward button the pdf will show up in IE.
I also tries using fileOuput stream instead of servletoutputstream
     FileOutputStream fout = new FileOutputStream( file );
               outStream.writeTo(fout);
               fout.close() ;
               outStream.close() ;
In this case IE does nothing but it works on netscape or mozilla
This is running on websphere 5.0 , apache webserver on linux env
But i need to get this worked on IE any help would be greatly appreciated!
Thanks in Advance
