But I am using the ServletOutputStream to display the results in the
following code snippet...
The problem I have is that the ServletoutputStream does not display the
content identified/added by pdfContentByte. Any help here ??????
ServletOutputStream ServletOutputStream out =
response.getOutputStream();
baos.writeTo(out);
out.flush();
thanks

Below is the code I have used to diaplay/open pdf file
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;
}
if ( !fFile.exists() || !fFile.canRead() )
{
System.out.println("You have specified an
invalid file to download. Please check and try
again.");
return;
}
res.setContentType("application/force-download");
res.setHeader("Content-disposition",
"attachment;filename=" + sFileName);
res.setHeader("Cache-control", "must-revalidate");
ServletOutputStream sosCur = res.getOutputStream();;
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)
{
System.out.println("Failed to download the file
\""
+ sFile + "\"" + ex.getMessage());
}
finally
{
try
{
if ( bisFile != null
)
bisFile.close();
}
catch(Exception ex)
{
}
if ( sosCur != null )
{
sosCur.flush();
}
}
Hope this will be helpful,
