I have an object PDFData with some attributes. One of them are Arraylist: One with String and another with a custom object (with some primitive attributes).
I need to render both list with a XSLT for create a PDF file with Apache-FOP. I've googled multiple ways to solve it but I have not found anything.
My class for render the PDF is:
public class PDFRender {
public static final String SUMMARY_REPORT_XSL = "summary_report.xsl";
//private final Logger log = LoggerFactory.getLogger(getClass());
public ByteArrayInputStream createPDFFile(ByteArrayOutputStream xmlSource) throws IOException {
ByteArrayInputStream inputStream = null;
InputStream template = Thread.currentThread().getContextClassLoader().getResourceAsStream(SUMMARY_REPORT_XSL);
StreamSource transformSource = new StreamSource(template);
FopFactory fopFactory = FopFactory.newInstance();
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
ByteArrayOutputStream pdfOutStream = new ByteArrayOutputStream();
StreamSource source = new StreamSource(new ByteArrayInputStream(xmlSource.toByteArray()));
Transformer xslfoTransformer;
try {
TransformerFactory transfact = TransformerFactory.newInstance();
xslfoTransformer = transfact.newTransformer(transformSource);
Fop fop;
try {
fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, pdfOutStream);
// Resulting SAX events (the generated FO) must be piped through to FOP
Result res = new SAXResult(fop.getDefaultHandler());
// Start XSLT transformation and FOP processing
try {
xslfoTransformer.transform(source, res);
inputStream = new ByteArrayInputStream(pdfOutStream.toByteArray());
} catch (TransformerException e) {
String msg = "Caught exception transforming source to generate PDF";
//log.error(msg, e);
throw new RuntimeException(msg, e);
}
} catch (FOPException e) {
String msg = "Caught FOP exception generating PDF";
//log.error(msg, e);
throw new RuntimeException(msg, e);
}
} catch (TransformerConfigurationException e) {
String msg = "Caught exception transforming source to generate PDF";
//log.error(msg, e);
throw new RuntimeException(msg, e);
}
return inputStream;
}
public ByteArrayOutputStream getXMLSource(PDFData data) throws Exception {
JAXBContext context;
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
try {
context = JAXBContext.newInstance(PDFData.class);
Marshaller m = context.createMarshaller();
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
m.marshal(data, outStream);
} catch (JAXBException e) {
String msg = "Caught exception marshalling application to generate PDF";
//log.error(msg, e);
throw new RuntimeException(msg, e);
}
return outStream;
}
}
PDFDatais as follows:
@XmlRootElement(name = "PDFData")
public class PDFData {
public String clientName;
public String clientProfile;
public String clientLang;
public URL clientLogo;
public ObjectId verificationId;
public String verificationCountry;
public String verificationDocumentType;
public List<Page> verificationPages = new ArrayList<>();
public String verificationTemplateName;
public Long verificationTime;
public List<ActionResult> verificationActions = new ArrayList<>();
public List<String> verificationMrz = new ArrayList<>();
/* ... */
}
My XSLT has no relevance because I don't have anything yet about it. Maybe just for comment it, is relevant that when I have to access to some attribute (for example clientName), I do it as follows:
<xsl:when test="clientName = 'Test client'">Orange</xsl:when>
I am using XSLT 1.1 with Jar dependency 'org.apache.xmlgraphics:fop:1.0' (version 1.1. dependencies don't load with gradle, I don't know why).
Summary: Someone knows how to render a Java List to a XSL template?
Thanks in advance!
UPDATE 1: Well... I have found a solution here. It solves one of my problems. I can get all the values. But now I have another problem. How can I loop over them?
UPDATE 2: @KevinBrown thinks that my XSLT could be important, so here is my XSLT:
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format">
<xsl:template match="PDFData">

UPDATE 3: Woohooo!! This weekend I have tried some solutions and I have obtained a loop:
<xsl:for-each select="verificationMrz">
<xsl:variable name="i" select="position()" />
<xsl:value-of select="$i" />
</xsl:for-each>
Ok, cool! But when I try to access the list with the index (<xsl:value-of select="verificationMrz[$i]" />) I don't get any value. I have checked if the list is not empty with <xsl:value-of select="verificationMrz[1]" /> and it works nice. So I think my problem is with variable i, maybe data type? I don't know...
