Hi Alan,

as far as I remember the stylesheets for pdf-generation have moved from core into the pdf-output-plugin.

So you may be looking at outdated style sheets. Which might also explain the errors you are getting (some changes were required in the transformations to accomodate that last fop-update).

Check out plugins/org.apache.forrest.plugin.output.pdf/resources/stylesheets for the current stylesheets (from head). After using Forrest with the pdf-plugin for the first time, you will also find the stylesheets in build/plugins/org.apache.forrest.plugin.output.pdf/resources/stylesheets.

Yet I agree with Brian, these style sheets were designed to be used in a pipeline, so you may have to make some major adjustments.

Hi All,

I am writing a program similar to pdf output plugin to convert xdoc pages in xml document ( xdoc similar to http://xmlgraphics.apache.org/fop/index.xml), and would like to generate the pdf output using fop (0.95 on Mac os 10.5) as shown in the following. However I am getting the following errors from console.

(Location of error unknown)org.apache.fop.fo.ValidationException: Error(Unknown location): For fo:simple-page-master, fo:region-body must be declared before fo:region-before.

1. Where can I find the xsl to convert from xdoc to fo. I find one from apache forrest distribution( apache-forrest-0.8/main/webapp/skins/common/xslt/fo/document-to-fo.xsl)? Or Am I using the wrong one for converting from xdoc to fo?

2. Is anything wrong with my code?


public class fop {
public static void main(String[] args) throws Exception {
// configure fopFactory as desired
            FopFactory fopFactory = FopFactory.newInstance();
            // configure foUserAgent as desired
            FOUserAgent foUserAgent = fopFactory.newFOUserAgent();

            // Setup output
OutputStream out = new java.io.FileOutputStream(new File("mypdf.pdf"));
            out = new java.io.BufferedOutputStream(out);

            // Construct fop with desired output format
Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, out);

            // Setup XSLT
            TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new StreamSource(new File("/Downloads/apache-forrest-0.8/main/webapp/skins/common/xslt/fo/document-to-fo.xsl")));

            // Set the value of a <param> in the stylesheet
            transformer.setParameter("versionParam", "2.0");

            // Setup input for XSLT transformation
Source src = new StreamSource("http://xmlgraphics.apache.org/fop/index.xml";);

// 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(src, res);
