John and folks,
First of all, thank you for your help.
I am still struggling with my PDF conversion. I am a
little headache with this. We have a lot of FOP/JAXP
professional here and hopefully I can get your
suggestion.
>From what you suggested me, I read a lot of reference
and resources. Now I tryed to use JAXP and FOP to
convert the binary tiff data into PDF format and I
got an error "Error 500:java.io.ByteArrayInputStream".
I know something wrong with my code. I just couldn't
figure out how to fix it. Below is the partcial codes
I wrote. Can you please take a look at my code and
give me your recommandation? I know I already
bothered you too much. You are not supposed to spend
time on this for me. If you don't have time, I totally
understand that. If you could help me, I will greatly
appreciate it. I use * to mark the part which I have
problem with. I also enclosed my XSL file here for
your reference.
My servlet:
public class ImageDownload extends HttpServlet {
...
public void doPost(HttpServletRequest req,
HttpServletResponse resp) throws
ServletException, IOException {
...
//get binary tiff data from database and put it in
an byte array
byte[] bt=(byte[]) v.elementAt(0);
DisplayToPdf(bt, resp);
}
public void DisplayToPdf(byte[] bt,
HttpServletResponse response) throws ServletException
{
try {
ByteArrayOutputStream out = new
ByteArrayOutputStream();
response.setContentType("application/pdf");
Driver driver = new Driver();
driver.setLogger(log);
driver.setRenderer(Driver.RENDER_PDF);
driver.setOutputStream(out);
ByteArrayInputStream bais=new
ByteArrayInputStream(bt);
File xslfile = new
File("C:/workspace/MaxTradDownload/Web
Content/html/Tiff2Pdf.xsl");
try {
driver.setOutputStream(out);
//Setup XSLT
TransformerFactory factory =
TransformerFactory.newInstance();
Transformer transformer =
factory.newTransformer(new StreamSource(xslfile));
//*assign ByteArrayInputStream bais to image
variable in xsltfile, seems like it is not working.
transformer.setParameter("image", bais);
//Setup input for XSLT transformation
//*Here, I need to do something to convert
ByteArrayInputStream into Source type. I haven't
figure out how to do or if it is possible
//Source src =
team.getSourceForProjectTeam();
//Resulting SAX events (the generated FO)
must be piped through to FOP
Result res = new
SAXResult(driver.getContentHandler());
//Start XSLT transformation and FOP
processing
//* I need to work on the first parameter
transformer.transform((Source)bais, res);
byte[] content = out.toByteArray();
response.setContentLength(content.length);
response.getOutputStream().write(content);
response.getOutputStream().flush();
} finally {
out.close();
}
} catch (Exception ex) {
throw new ServletException(ex);
}
}
}
