Error using servlet for external-graphic
Hi all, I'm trying to use a servlet to generate a dynamic image and am seeing the following error: 6/26/02 3:16 PM -- http://localhost:8080/client/DoGetImage?w=200&h=100&leftmargin=1.5 6/26/02 3:16 PM -- Could not load external SVG: The current document is unable to create an element of the requested type (namespace: http://www.w3.org/2000/svg, name: head).Error while creating area : No ImageReader for this type of image (http://localhost:8080/client/DoGet Image?w=200&h=100&leftmargin=1.5) The relevant FO source is: http://localhost:8080/client/DoGetImage?w=200&h=100&leftmargin=1.5"/> The image displays fine in a browser, but after adding some logging code to the servlet it appears that FOP is not calling it at all. Does anybody know what might be causing this error (querystring in the URL, use of a port number, etc)? Much thanks, Joel Stevenson

J.Pietschmann wrote: Well, obsolete or not, it works, is available, platform neutral, easy to install and provides support for a wide range of graphics formats, some of them rather obscure. Do you know of a JAI implementation, preferably OSS and/or freely available, which supports all common subformats of TIFF, PNG, BMP and perhaps a few more? Well, that's right and what is more JAI strongly requires at least jdk1.3 :( -- Oleg Tkachenko Multiconn International Ltd

Re: Weird behaviour of Apache fop
Just curious - why are you processing input as string instead of tree? xslt is not text processing language, it's intended for tree transformations. I believe this string processing example is a very convolute analogue of 3 simple xslt templates: Moreover, these templates has advantage over string processing - they are really build output tree by elements, while you are just outputting string values like "foo", that's why fop doesn't see element b here - it's just text node holding *characters* '<', 'b', '>', 'f' etc. This string has to be parsed by xml parser in order to be tree or sax events, that is particular reason you cannot avoid transformation to string and reparsing using this technique. The only reason for using this string-oriented stuff is ill-formed input, like html, but you can use 1) tidy software to get xhtml, 2) html parser (apache has one, libxml is able to parse html also).

Here is how I convert DOM to PDF directly, without creating files or string

throws TransformerConfigurationException,
TransformerException {
Document doc = null;
try {
// helper to create DOM documents
doc = XMLUtilities.createDocument();
} catch (Exception e) {
throw new TransformerConfigurationException();
}
Node n = doc.importNode(node, true);
doc.appendChild(n);
DOMSource domSource = new DOMSource(doc);
DOMResult domResult = new DOMResult();
transformer.transform(domSource, domResult);
Node n2 = domResult.getNode();
return (Document) n2;
}
// transforms FO DOM into PDF and sends it to OutputStream
protected void createPdf(Document doc, OutputStream fOut)
throws IOException, FOPException {
InputSource inputSource = XmlHelper.dom2inputSource(doc);
ByteArrayOutputStream out = new ByteArrayOutputStream();
Hierarchy hierarchy = Hierarchy.getDefaultHierarchy();
Logger log = hierarchy.getLoggerFor("fop");
log.setPriority(Priority.ERROR);
File userConfigFile = new File(FOP_CONFIG);
Options options = new Options(userConfigFile);
Driver driver = new Driver(inputSource, out);
driver.setLogger(log);
driver.setRenderer(Driver.RENDER_PDF);
driver.run();
byte[] content = out.toByteArray();
fOut.write(content);
out.flush();
out.close();
}
/*
import org.apache.xalan.serialize.Serializer;
import org.apache.xalan.serialize.SerializerFactory;
import org.apache.xalan.templates.OutputProperties;
*/
// and dom2inputSource, which converts any DOM to SAX InputSource
without
// writing to disk
public static InputSource dom2inputSource(Document doc)
throws IOException {
InputSource is = null;
Serializer serializer = SerializerFactory.getSerializer(
OutputProperties.getDefaultMethodProperties("xml"));
CharArrayWriter caw = new CharArrayWriter();
serializer.setWriter(caw);

Subject: RE: FOPServlet and XML string
I'm having the same issues, so if you find a solution, please post. But, it
seems like you could use the XALAN function XSLTransform to convert a DOM
document or a string using an XSL file to either a FO file or another DOM
document. XSLTInputHandler will only take java.io.File parameters, but I've
seen examples of using the JAXP Transformer to do the job as well. See:
http://www.devx.com/xml/articles/vp101201/vp101201-1.asp. It seems as if
this could be modified to use a StringReader and/or StringWriter. Let me

RE: Embedded FOP question.
Thanks for your help! I needed to change it to use a ByteArray so that I could set the content length for IE. Other than that it worked great. Thanks again.

There is sample code in the archive at http://marc.theaimsgroup.com/?l=fop-user&r=1&w=2# http://marc.theaimsgroup.com/?l=fop-dev&r=1&w=2# For producing and rendering a DOM, look up javax.xml.transform.dom.DOMResult in the JAXP documentation coming with your XSLT processor and look for render(Document) in src/org/apache/fop/apps/Driver.java Unless you need to manipulate the intermediate DOM, it is usually more effective to use SAX to tie the XSLT processor to the FOP driver, for example http://marc.theaimsgroup.com/?l=fop-user&m=102400770318682&w=2 J.Pietschmann

Some seemingly "simple" Formatting Questions
I'm relatively new to using FOP. I've got a document working fairly well, but am having a difficult time doing a few things that I would have thought to be "simple". 1. Cannot set the TOP MARGIN of a "xsl-region-before". Setting it to anything is ignored and the data is always printed at the very top of the page. 2. Cannot set the FONT of a "fo:retrieve-marker" used in a "xsl-region-before". It seems to ignore my font setting and always print the same size. 3. Cannot set the height of a "fo:leader" to a small amount. The output is always preceeded by more white space than is desired. 4. Problem using "keep-with-next" across page and column breaks of multi-column pages. Thanks to Chuck Paussa, I made great headway on better controlling KEEPS in a multi-column document by putting the data in TABLE CELLS. The KEEP-TOGETHER seems to work fine within TABLE cells; however, the KEEP-WITH NEXT does not appear to work. Any insights on this would be greatly appreciated. Thanks, Paul Thibodeaux
