Problem adding Non-English Font
We have a problem adding a new font (a Chinese one) to fop. We are trying to produce UTF-8 reports in Chinese using fop from a servlet. We have the reports going ok in English. We have gotton a Chinese ttf font file and tried to follow the instructions listed in the Font section of the fop web site. We ran the font metrics utility to produce the font metrics xml file and added the definition of the new font to the userConfig.xml. However, it is not clear where to place the generated font metrics xml file. We cannot find any similar files elsewhere in the directory structure. Has anybody done this before or know where they should be located? Also in the font instructions on the web site, it says to start fop with a -c command line option. However, we are doing this in a Servlet. How do we invoke fop with this option set from another Java class?

RE: FOP Servlets being invoked twice
Thanks for the tip on IE behaving like this.
I don't agree with the suggestion about using DOM to
build up a document. Intuitively it does not make sense
to have Xalan parse the document out when the program that
constructs it knows the structure. There are several
problems with this, however:
(1) It is more convoluted to code DOM than dealing with strings.
(2) It will be slower. Xalan does not use DOM to store
nodes in an xml document since it creates too many objects.
(3) It will take more memory since storing the document in
a DOM will use more memory than a StringBuffer.

As far as I know, IE has always done 2 requests per mime type that
it
doesn't handle internally. See Article ID: Q293336 in the M$ knowledge
base. Netscape and all others only do 1 request. If anyone knows a
configuration that can get IE to behave, please let me know
I do suggest adding
response.addHeader("Content-Disposition", "inline;
filename=report.pdf");
it will fix some glitches in IE5.0, and also have you considered using
a
Dom Document rather than a string to pass your xml around? It would
save
you from having to parse it twice when you go from your business object
to
Xalan, and from Xalan to FOP.

.pdf extension
We had exactly the same problem with the file extensions. IE
seems to ignore the content type directive. Once we renamed
our servlet url to "report.pdf" IE was able to pick up
the reports.

If you check the mailing list archives you will see that at least one
person
has seen this problem (with IE I think) and can't find a way around it.
However I don't see it myself so it might be fixable.

This is the only bit I am worried about - how does this help?
Since you've mentioned servlets I'll throw my problem into the fray.
I've seen the content size problem (which you have correctly solved in
your code)
but now I have a problem with a particular build of IE. Basically the
PDF doesn't appear -
in fact neither does acrobat reader
The problem occurs on the IE version 5.50.4522.1800 and not with other
IE5.5 versions, eg.
5.50.4134.0600.
(Incidently the data is submitted to the servlet using Post - apparently
this is
the cause of the bug in IE)
Now I got so fed up with this that I tried saving the PDF file to disk
and then issuing
a redirect to the static PDF file. Hooray this works in the problem
version of IE.
Oh b(*&^(*er it no longer works in the older versions of IE.
I've tried the servlet "sendRedirect", I've tried a Location header with
relative and
absolute URLs, I've even just tried a "Refresh" header. Nothing seems to
work.
So folks - what are your servlet experiences?
I feel like I'm going round in circles here.
The one thing I haven't really done is to change the URL to end with
".pdf"
Basically I can't create a class called "something.pdf" so haven't
created a servlet
with that name yet. I've tried servletname;stupidie.pdf but that didn't
seem to help.

FOP Servlets being invoked twice
I have a problem with a servlet, which serves up pdf documents,
invoking the servlet twice for every time I request the
url using my browser. The pdf document is produced
correctly in both instances. Anybody else seen this
problem, know what it is, or have a constructive suggestion?
The servlet gets data from a database, formats into xml,
transforms it with Xalan, then again to a pdf, sending
the content to a byte array where it is then written to
the output stream. Here is a code fragment:
Writer writer = new StringWriter();
// Get an xslt processor factory
TransformerFactory tFactory = TransformerFactory.newInstance();
// Create the 3 objects the XSLTProcessor needs to perform the
transformation.
ReportInfo reportInfo = getReportData(request,res);
String xml = reportInfo.getXml();
StringReader stringReader = new StringReader(xml);
Source xmlSource = new StreamSource(stringReader);
Source xslSheet = getXSLInput(reportInfo.getReportNo());
StreamResult xmlResult = new StreamResult(writer);
Transformer transformer = tFactory.newTransformer(xslSheet);
// Perform the transformation.
transformer.transform(xmlSource, xmlResult);
// send output from xsl transformation to a string reader
// create a input source containing the xsl:fo file which can be fed to
Fop
Reader reader = new StringReader(writer.toString());
writer.flush();
writer.close();
//set Driver methods to start Fop processing
Driver driver = new Driver();
driver.setRenderer("org.apache.fop.render.pdf.PDFRenderer",".14");
driver.addElementMapping("org.apache.fop.fo.StandardElementMapping");
driver.addElementMapping("org.apache.fop.svg.SVGElementMapping");
driver.addPropertyList("org.apache.fop.fo.StandardPropertyListMapping");
driver.addPropertyList("org.apache.fop.svg.SVGPropertyListMapping");
// send pdf writer output to a byte array stream
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PrintWriter printWriter = new PrintWriter(baos);
driver.setWriter(printWriter);
driver.buildFOTree(parser, new InputSource(reader));
driver.format();
driver.render();
// send the bytes out to the servlet output stream
res.setContentType("application/pdf");
res.setContentLength(baos.size());
long sixty = System.currentTimeMillis() + 60*1000;
res.setDateHeader("Expires", sixty);
baos.writeTo(res.getOutputStream());
res.flushBuffer();
