Problems with Apache FOP and Barcode4j
Hi folks,
I'm upgrading my FOP version from 0.20 up to 0.95 and I'm getting two
problems.
The first one, and most important, is that I can't generate barcodes with
Apache FOP and Barcode4j projects. I don't know why but I'm getting this
error:
javax.xml.transform.TransformerException: org.xml.sax.SAXException:
Mismatch: page-sequence (http://www.w3.org/1999/XSL/Format) vs. root
(http://www.w3.org/1999/XSL/Format)
I know that this error uses to be a follow-up error but I have no more
detail and I'm lost since I have reached a strange situation.
I have the following code on my xslt.
- Definition:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:barcode="org.krysalis.barcode4j.xalan.BarcodeExt"
xmlns:svg="http://www.w3.org/2000/svg"
extension-element-prefixes="barcode">
- Template:
<xsl:template match="texto[@class='CODIGO_BARRAS']">
<fo:block>
<fo:instream-foreign-object>
<xsl:variable name="barcode-cfg">
<barcode>
<code128>
<human-readable>none</human-readable>
<height>5mm</height>
<quiet-zone enabled="false"/>
</code128>
</barcode>
</xsl:variable>
<xsl:copy-of select="barcode:generate($barcode-cfg, .)"/>
</fo:instream-foreign-object>
</fo:block>
</xsl:template>
- Call example:
<texto class="CODIGO_BARRAS" text-align="left" font-size="12pt"
module="0.45" height="10" >D106696</texto>
- Java code:
The following code throws the exception.
public void convertXmlToPdf(final StreamSource xmlSource, final String
xsl, final OutputStream pdf) throws Exception {
FOUserAgent foUserAgent = instance.fopFactory.newFOUserAgent();
// todo, configure urls.
foUserAgent.setBaseURL("file:///C:/TRIBUTOS/apps/gt_ear/build/gt_ear/gt_web/");
foUserAgent.setFontBaseURL("file:///C:/TRIBUTOS/apps/gt_ear/build/gt_ear/gt_web/");
foUserAgent.setAuthor("Miguel Tablado");
//Setup XSLT
Fop fop = instancia.fopFactory.newFop(MimeConstants.MIME_PDF,
foUserAgent, pdf);
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new
StreamSource(xsl));
// Parámetro PATH de las imagenes
transformer.setParameter("AG_XSLFO_PATH_IMAGES",
AGFunciones.agregarProtocoloFile(AGConfig.get("VirtualDirTemplates")) +
"/images");
//Resulting SAX events (the generated FO) must be piped through to
FOP
Result res = new SAXResult(fop.getDefaultHandler());
//Start XSLT transformation and FOP processing
transformer.transform(xmlSource, res);
}
The following one creates the .fo file with no problems.
private void convertXML2FO(final StreamSource src, final String xslt)
throws IOException, TransformerException
, FOPException {
//Setup output
final File fo = new File(AGConfig.get("writeXmlFoPdfIntoFile"));
final OutputStream out = new FileOutputStream(fo);
try {
//Setup XSLT
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new
StreamSource(xslt));
// Parámetro PATH de las imagenes
transformer.setParameter("AG_XSLFO_PATH_IMAGES",
AGFunciones.agregarProtocoloFile(AGConfig.get("VirtualDirTemplates")) +
"/images");
//Resulting SAX events (the generated FO) must be piped through
to FOP
Result res = new StreamResult(out);
//Start XSLT transformation and FOP processing
transformer.transform(src, res);
} finally {
out.close();
}
}
The .fo generated snippet is something like this:
<fo:block>
<fo:instream-foreign-object>
<svg:svg height="1.3316mm" viewBox="0 0 120.54 1.3316" width="120.54mm">
<svg:g style="fill:black; stroke:none">
<svg:rect height="1.3316" width="0.42" x="0" y="0"/>
<svg:rect height="1.3316" width="0.21" x="0.63" y="0"/>
...
<svg:rect height="1.3316" width="0.42" x="120.12" y="0"/>
</svg:g>
</svg:svg>
</fo:instream-foreign-object>
</fo:block>
Trying to find out the original problem I have tried two things, the first
one is to replace Barcode4j call to svg code.
Any problem, the resultant pdf has a pretty barcode.
The second one, that follows me to the second problem mentioned at
introduction, has been configuring logs to get more information,
but I didn't get success. I'm logging with Bea Weblogic 8.1 SP 5 system logs
whose are java.util.logging and they are printing on FOP Exceptions, but not
INFO logs.
How can I configure them to succeed?
Java properties are setted and it doesn't work, I tryied to filter logs, but
there is no special handler...
Many thanks, and excuse me for the text!
Miguel.

I got it, what I have done is to include a line on fop.bat including the jar
since the environment variable didn't work.
So I have include some libraries to my lib project directory and it has
worked. I pray for proper logging :)
Thanks.

Posted by Tobias van Treeck <tv...@nepatec.de>.
Hui Miquel,
i also had this problem but then i realized that i forgot the following
jar:
barcode4j-fop-ext.jar
You also need those:
barcode4j.jar
batik-all-1.7.jar
avalon-framework-4.2.0.jar
commons-io-1.3.1.jar
commons-logging-1.0.4.jar
fop.jar
serializer-2.7.0.jar
xalan-2.7.0.jar
xercesImpl-2.7.1.jar
xml-apis-1.3.04.jar
xml-apis-ext-1.3.04.jar
xmlgraphics-commons-1.3.1.jar
Do you got all those?

I have modified my xslt in order to apply only the barcode template and I
get the simplest fo file as you said, but unfortunately it doesn't works, it
doesn't render the svg (the barcode nodeList, really) nor it prits out any
exception.
By the way if I launch the fo file from command line I get problems finding
barcode classes. I don't know what I'm doing wrong because I have put the
jar path on the classpath environment variable.
About Xalan version, I'm using 2.7.1 and it is working from Weblogic
container, not jdk installation one.
Any idea?
Tx, Miguel.

Posted by Tobias van Treeck <tv...@nepatec.de>.
Hi Miguel,
i had a similar problem recently. I also generated a PDF with a barcode
and an image.
I got the exact same error you got (root vs. page-sequence) and the
reason was a wrong parameter in a table i used (for the column-with i
used % instead of cm)
Now i have serval suggestions for you:
1. Try to isolate your barcode 'code' - meaning create a document with
just the barcode and run it. Does that work?
2. I used the same barcode 'code' like you but the following proved to
be better for me:
Namespace:
xmlns:barcode="http://barcode4j.krysalis.org/ns"
<block ...>
<fo:instream-foreign-object>
<barcode:barcode>
<xsl:attribute name="message">
<xsl:text>1234567890</xsl:text>
</xsl:attribute>
<barcode:codabar>
<barcode:height>15mm</barcode:height>
<barcode:module-width>0.3mm</barcode:module-width>
<barcode:wide-factor>3.0</barcode:wide-factor>
<barcode:quiet-zone enabled="true">10mw</barcode:quiet-zone>
</barcode:codabar>
</barcode:barcode>
</fo:instream-foreign-object>
Try that barcodeversion in a separate stylsheet and run it.
3. Which version of xalan are you using? Put the newest one with the
endorsed mechanism (http://java.sun.com/j2se/1.4.2/docs/guide/standards/
) into your jdk.

Thanks for the extensive additional data. I might have the problem now.

This indicates that the Barcode4J FOP extension is not correctly set up
with FOP. Please note that FOP 0.95 needs a different extension than FOP
0.20.5 because the extension APIs have changed. Please put
"barcode4j-fop-ext-complete.jar" (from Barcode4J 2.0) into your
classpath (and remove the old JAR). The above error message should then
go away and the barcodes should appear.
But that doesn't really explain why you got the "mismatch" error. Maybe
we need to take this one step at a time.

I have done it but I got the same report.
Code...
public class AGEstandarXSLTErrorListener implements ErrorListener {
private final AGMap report;
public AGEstandarXSLTErrorListener(final AGMap _report) {
super();
this.report = _report;
}
public void error(final TransformerException exception) throws

this.report.get(AGFrontServlet.ERRORES) + "{ ERROR XSLT =" +

}
public void fatalError(final TransformerException exception) throws
TransformerException {
/*More of the same*/
}
public void warning(final TransformerException exception) throws
TransformerException {

}
}
Where AGMap is a Hashmap wrapper.

An alternative is to just set a simple ErrorListener implementation on
the Transformer to override Xalan's default ErrorListener. I've attached

Re: Problems with Apache FOP and Barcode4j
Posted by Miguel Tablado <mi...@gmail.com>.
Hello Andreas and others,
I'm using xalan 2.7.1. And this is the xslt processor guessed from the
StackTrace (I doubted if Weblogic was discarding it).
org.xml.sax.SAXException: Mismatch: page-sequence
(http://www.w3.org/1999/XSL/Format) vs. root
(http://www.w3.org/1999/XSL/Format)
StackTrace:
org.apache.xalan.templates.ElemLiteralResult.execute(ElemLiteralResult.java:725))
org.apache.xalan.transformer.TransformerImpl.executeChildTemplates(TransformerImpl.java:2339))
I have generated the fo file and it is correct, furthermore if I launch the
command line with -d -fo options i get the pdf file and some messages that
I'd discard as font errors. Wouldn't I?
- The call:
fop -d -fo
c:\bea8\user_projects\domains\tributos\logs\tempPdfGaudi\gaudiXMLFOPDF.fo
out.pdf

points. (fo:block, location: 22/38)
By the way, looking at BarcodeExt source I have notice that you can work
using name-spaces or not, and as I wasn't using them I have tryed the
opposite as follows:
<fo:block>
<fo:instream-foreign-object>
<bc:barcode message="Hello World!"
xmlns:bc="org.krysalis.barcode4j.xalan.BarcodeExt">
<bc:code128>
<bc:height>8mm</bc:height>
<bc:human-readable>none</bc:human-readable>
<bc:length>25mm</bc:length>
</bc:code128>
</bc:barcode>
</fo:instream-foreign-object>
</fo:block>
It throws another exception which is (as you mentioned):
Message:
org.xml.sax.SAXException: endElement() called for fo:root where there is no
current element.
The resultant .fo file is trunked/uncomplete and the last rendered object is
the generated svg barcode. I know the namespace I'm using is for processing
the barcode at xslt process and that I could do it at fop process using
"http://barcode4j.krysalis.org/ns" namespace, let's go!
FOP is not generating the svg object. Surely the reason is this that I get
from command line:

But I don't understand why the FOP ElementMapping class doesn't found them
if I have setted the CLASSPATH to go for barcode-ext-complete jar, any idea?

Just to be sure: Can you try using a different XSLT processor (or
simply a more recent version of Xalan)? Reason I'm asking is that I
seem to remember that some Xalan versions swallow exceptions. It
recovers, hands control back over to FOP, but the node in question
(where the error originates; if I judge correctly, the page-sequence
in question) will still not have been processed completely, so FOP
will have received a startElement(), but no endElement().
Not that this will immediately solve your issue, but if the XSLT
processor would terminate, then you should at least get a more
appropriate error-message.
Another thing to try to receive a more meaningful error message:
- first generate the FO from the XML+XSLT (by means of the '-foout'
command-line option), and check if the FO is valid XML
- if the first step succeeds, then render the resulting FO to the
desired output format, preferably in debug-mode ('-d') to receive as
much relevant info as possible.
If this doesn't help, don't hesitate to post back here!
HTH!
