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,

Hi,
I am using a Servlet to create a pdf file and
display the output
through the servlet. The pdf file gets created in
the Server directory
with all thePdfContentByte content. Any content
added through
pdfContentByte is not shown in the servlet output,(
while
non-pdfcontentbyte content is shown in the servlet
output). The file
has all these content (but does not display through
Servletoutputstream)
Can you please help?
The code is listed below. Can someone tell me what
I am doing wrong
here?
Thanks in advance for your help.
regards
Murali Thirumalai
Document doc = new
Document(PageSize.LETTER.rotate());
PdfWriter writer = PdfWriter.getInstance(doc, new
FileOutputStream("HTRSCertificates.pdf"));
ByteArrayOutputStream baos = new
ByteArrayOutputStream();
PdfWriter.getInstance(doc, baos);
doc.open();
PdfContentByte cb = writer.getDirectContentUnder();
doc.add(Chunk.NEWLINE);
doc.add(new Chunk("Test content"));
helv = BaseFont.createFont("Helvetica",
BaseFont.WINANSI, false);
// step 4: adding content
for (int i=0; i<list1.size();i++)
{
cb.beginText();
p1 = (Participant) list1.get(i);
cb.setFontAndSize(helv,24);
Font font = new Font(helv, 12, Font.ITALIC);
doc.add(new Chunk(p1.getFirstName()+' ' +
p1.getLastName()));
cb.showTextAlignedElement.ALIGN_CENTER,p1.getFirstName()+'
' +
p1.getLastName(), doc.getPageSize().width() / 2,
350, 0);
cb.showTextAligned(Element.ALIGN_CENTER, clsDt,
doc.getPageSize().width() / 2, 250, 0);
cb.endText();
if (i<list1.size()-1) doc.newPage();
}
// step 5: closing the document
doc.close();
PdfWriter.getInstance(doc, baos);
response.setHeader("Expires", "0");
response.setHeader("Cache-Control",
"must-revalidate, post-check=0,
pre-check=0");
response.setHeader("Pragma", "public");
// setting the content type
response.setContentType("application/pdf");
// the contentlength is needed for MSIE!!!
response.setContentLength(baos.size());
// write ByteArrayOutputStream to the
ServletOutputStream
ServletOutputStream out =
response.getOutputStream();
baos.writeTo(out);
out.flush();
