The TOC was regenerated, but the page numbers are missing

[Jmik01]

Dear ALL,
I would like to ask why, when I regenerate the TOC, I lose the page numbers. I am using Spring Boot 2.7.18 and Java 11. For docx4j I am using:


<!-- https://mvnrepository.com/artifact/org. ... erenceImpl -->
<dependency>
<groupId>org.docx4j</groupId>
<artifactId>docx4j-JAXB-ReferenceImpl</artifactId>
<version>11.5.5</version>
</dependency>


Below the code I use to regenerate the TOC:



public static boolean processToc(File inputFile, File outputFile) throws Throwable {
boolean bResult = true;
try {
// Carica il documento Word
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(inputFile);

//verica se e' presente una TOC
if (isTocPresent(wordMLPackage) == null) {
bResult = true;
}
else {
//0. Trova e rimuove la TOC esistente
int tocIndex = removeExistingToc(wordMLPackage);
if (tocIndex < 0) {
bResult = false;
}
else {
//1. si sanificano gli stili
fixMissingStyleNames(wordMLPackage);

//2. si genera la nuova TOC con le opzioni corrette
TocGenerator tocGenerator = new TocGenerator(wordMLPackage);

// Usa \n per preservare la numerazione dei capitoli
// \o "1-4" per includere livelli 1-4
// \h per includere hyperlink
// \z per nascondere i tab leader nel Web Layout View
tocGenerator.generateToc(tocIndex, "TOC \\o \"1-4\" \\h \\z", true);

// 3. si aggiornano i riferimenti
tocGenerator.updateToc(true);

// 4. si salva il documento
wordMLPackage.save(outputFile);
}
}
}
catch (Throwable thwExc) {
bResult = false;
}

return bResult;
}


public static SdtBlock isTocPresent(WordprocessingMLPackage wordMLPackage) throws Throwable {
TocFinder tocFinder = new TocFinder(); // Nuova istanza per ogni esecuzione
tocFinder.walkJAXBElements(wordMLPackage.getMainDocumentPart());
return tocFinder.getTocSDT(); // Verifica se ha trovato una TOC
}

private static int removeExistingToc(WordprocessingMLPackage wordMLPackage) throws Throwable {
MainDocumentPart mainPart = wordMLPackage.getMainDocumentPart();
List<Object> content = mainPart.getContent();

for (int i = 0; i < content.size(); i++) {
Object obj = content.get(i);

// Cerca SdtBlock che contiene la TOC
if (obj instanceof SdtBlock) {
SdtBlock sdtBlock = (SdtBlock) obj;

// Verifica se è una TOC
if (isTocBlock(sdtBlock)) {
content.remove(i);
return i;
}
}

// Cerca anche nei paragrafi per campi TOC
if (obj instanceof P) {
P paragraph = (P) obj;
if (containsTocField(paragraph)) {
content.remove(i);
return i;
}
}
}

return -1;
}


Thanks in advance for your help
Michele

Using java Syntax Highlighting

tocGenerator.generateToc(tocIndex, "TOC \\o \"1-4\" \\h \\z", true);

// 3. si aggiornano i riferimenti
tocGenerator.updateToc(true);
 

Parsed in 0.012 seconds, using GeSHi 1.0.8.4

tocGenerator.generateToc with true parameter means skip page numbering.

updateToc(true) means skip page numbering; but no need for this line following generateToc.

If you want page numbering, set the generateToc to false, and add docx4j-export-fo (which provides the page model). Please note that this page model is not identical to Word's so the page numbers are indicative only.

Hi Jason,
in my project I was using the following implementation of docx4j:

<dependency>
<groupId>org.docx4j</groupId>
<artifactId>docx4j-JAXB-ReferenceImpl</artifactId>
<version>11.5.5</version>
</dependency>

I followed your instructions by adding:

<dependency>
<groupId>org.docx4j</groupId>
<artifactId>docx4j-export-fo</artifactId>
<version>11.5.5</version>
</dependency>

but this caused the following imports used in my project:

import javax.xml.namespace.NamespaceContext;
import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathConstants;
import javax.xml.xpath.XPathFactory;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;

the following error:

The package javax.xml.namespace is accessible from more than one module: <unnamed>, java.xml

I solved it with exclusions in the following way:

<dependency>
<groupId>org.docx4j</groupId>
<artifactId>docx4j-export-fo</artifactId>
<version>11.5.5</version>
<exclusions>
<exclusion>
<groupId>xml-apis</groupId>
<artifactId>xml-apis</artifactId>
</exclusion>
<exclusion>
<groupId>javax.xml</groupId>
<artifactId>javax.xml-api</artifactId>
</exclusion>
<exclusion>
<groupId>xalan</groupId>
<artifactId>xalan</artifactId>
</exclusion>
<exclusion>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
</exclusion>
</exclusions>
</dependency>

Finally:

TocGenerator tocGenerator = new TocGenerator(wordMLPackage);

tocGenerator.generateToc(tocIndex, "TOC \\o \"1-4\" \\h \\z", false);

wordMLPackage.save(outputFile);

It seems to work!!!

I’ll keep you updated!

Frustrating when that happens...

You can run maven dependency:tree on your project to see what is coming from where.

Did you try adding a module-info.java such as https://github.com/plutext/docx4j/blob/ ... -info.java
