Getting 'WrappedRuntimeException' when using XSL-FO in an Xpage - xslt

Question

I am trying to create a PDF from the contents of an xpage. I am following the format that Paul Calhoun used in Notes in 9 #102. I am able to create PDF's for views, but having trouble creating one for a document. I do not think the error is in Paul's code so I am not including it here, although I can if need be.
To generate the XML to display I use the generateXML() method of the document class in java. I get a handle to the backend document and then return the XML. The XML appears well formed, the top level tab is <document>. I pass this XML to the transformer which is using Apache FOP. All of my code is contained in the beforeRenderResponse of an xAgent.
The XSL stylesheet that I am using is a stripped down version to just get a proof of concept to work. I am going to include it, because the problem likely resides with this code. I am totally new to XSL.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
version="1.1"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
exclude-result-prefixes="fo">
<xsl:output
method="xml"
version="1.0"
omit-xml-declaration="no"
indent="yes" />
<xsl:param
name="versionParam"
select="'1.0'" />
<xsl:template match="document">
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
<fo:layout-master-set>
<fo:simple-page-master
master-name="outpage"
page-height="11in"
page-width="8.5in"
margin-top="1in"
margin-bottom="1in"
margin-left="1in"
margin-right="1in">
<fo:region-body />
</fo:simple-page-master>
</fo:layout-master-set>
<fo:page-sequence master-reference="A4">

space-after="5mm">
Apache FOP Proof of Concept.
</fo:block>
</fo:page-sequence>
</fo:root>
</xsl:template>
</xsl:stylesheet>
In the log file I get the message:
FATAL ERROR: 'com.ibm.xtq.common.utils.WrappedRuntimeException: D:\Program Files\IBM\Domino\<document form='PO'>
The error echos the entire XML in the log that it is trying to transform and ends with:
(The filename, directory name, or volume label syntax is incorrect.)'
Notice that Domino is trying to include the XML in a path. I know this is wrong, but don't know what to do to fix it.
EDIT: This is the Java class that runs the transformation. This code is from Paul Calhoun's demo.
import java.io.OutputStream;
import javax.xml.transform.Result;
import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.sax.SAXResult;
import javax.xml.transform.stream.StreamSource;
import org.apache.fop.apps.FOUserAgent;
import org.apache.fop.apps.Fop;
import org.apache.fop.apps.FopFactory;
public class DominoXMLFO2PDF {
public static void getPDF(OutputStream pdfout,String xml,String xslt, Boolean authReq, String usernamepass) {
try {
//System.out.println("Transforming...");
Source xmlSource,xsltSource; //Source xmlSource = new StreamSource("http://localhost/APCC.nsf/Main?ReadViewEntries&count=999&ResortAscending=2");
xmlSource = new StreamSource(xml); //Source xsltSource = new StreamSource("http://localhost/APCC.nsf/viewdata.xsl");
xsltSource = new StreamSource(xslt);// configure fopFactory as desired
final FopFactory fopFactory = FopFactory.newInstance();
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
// configure foUserAgent as desired
// Setup output
// OutputStream out = pdfout;
// out = new java.io.BufferedOutputStream(out);
try {
// Construct fop with desired output format
Fop fop = fopFactory.newFop(org.apache.xmlgraphics.util.MimeConstants.MIME_PDF,foUserAgent, pdfout);
// Setup XSLT
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(xsltSource);
//transformer.setParameter("versionParam", "Company List"); // Set the value of a <param> in the stylesheet
Source src = xmlSource; // Setup input for XSLT transformation
Result res = new SAXResult(fop.getDefaultHandler()); // Resulting SAX events (the generated FO) must be piped through to FOP
transformer.transform(src, res); // Start XSLT transformation and FOP processing
} catch (Exception e) {
} finally {
}
} catch (Exception e) {
e.printStackTrace(System.err);
}
}
}
This code is called in the xAgent using this line:
var retOutput = jce.getPDF(pageOutput, xmlsource, xsltsource, authReq, usernamepass);
The xmlsource is set with this line where the method returns XML using Document.generateXML():
var xmlsource = statusBean.generateXML(POdata, sessionScope.unidPDF);

Answer 1

Your problem is the XMLSource! When you look at Paul's code:
Source xmlSource = new StreamSource("http://localhost/APCC.nsf/Main?ReadViewEntries");
This points to an URL where to retrieve XML.On the other hand your code:
xmlsource = statusBean.generateXML(POdata, sessionScope.unidPDF);
contains the XML. So you need to change to:
String xmlstring = statusBean.generateXML(POdata, sessionScope.unidPDF);
Source xmlsource = new StreamSource(new java.io.StringReader(xmlstring));
I strongly suggest you try to keep all the Java in a java class, so you don't need to wrap/upwrap the objects in SSJS. Have a look at my series on FO too.
