Display a PDF file from local drive

Question

Hi,
I would like to display a pdf file that is actually stored on the portal server hard drive.
What I have tried to do is link an iFrame element to the url of the file: "D:
MyFolder
myFile.pdf"
But it doesn't work. I have the following error when trying to do that:
com.sap.tc.webdynpro.services.exceptions.InvalidUrlRuntimeException: Invalid URL=D:/MyFolder/myFile.pdf
Does this means that iFrame can only display http URLs ? What are the other ways to easily display pdf files ?? I'am stuck with that problem and can't find any other solution.
I also tried with "servletResponse.getOutputStream().write(fileByteContent);" but the problem is that I am not in a PAR application, and I don't have the servletResponse element and don't know how to get it.
Thanks for your help.

Hi,
   You can not access the .pdf file using the nornal path (c:
), use the following code to open the pdf in ur iframe, this will work i used it in my application.
String sFileName =
strCampCodeVal"_"nReqIdVal+".pdf";
String sFile =
"C:
SBLI
BCP
barcode_files
"+sFileName;
File fFile = new File(sFile);
     if ( fFile == null )
         System.out.println("System can not download the
                                 file at this time. Please try again later.");
              return;
//Checking the file for existence
     if ( !fFile.exists() || !fFile.canRead() )
         System.out.println("You have specified an
                   invalid file to download. Please check and try
                    again.");
         return;
//set the content type its important , try with applicatio/pdf also
     res.setContentType("application/force-download");
//seting the header
     res.setHeader("Content-disposition",
"attachment;filename=" + sFileName);
     res.setHeader("Cache-control", "must-revalidate");
     ServletOutputStream sosCur = res.getOutputStream();;
//reading the in and writing the stream
     BufferedInputStream bisFile = null;
          try
               byte [] bBuffer = new byte[4096];
               bisFile = new BufferedInputStream(new
                                                FileInputStream(fFile));
               int nBytes = -1;
                          while( (nBytes = bisFile.read(bBuffer, 0, 4096))!=-1 )
                   sosCur.write(bBuffer, 0, nBytes);
          catch(Exception ex){
This will resove your issue.All the best..
