Auto update TOC after merging documents

[patell.pranav]

Hi All,

Here is what I am doing
1. Generating 2 (or more) word documents using Docx4j
2. Using the trial version of Enterprise docx4j to merge these documents which works perfectly fine
3. However I cant get the TOC at the start of merged document to auto update, currently I have to right click on the TOC field and generate it manually.

I looked at the Enterprise Edition features and it states "support for TOC generate/update" but any help on how to do this will be appreciated.

Thanks
Pranav

Please see p38 of the Manual (included in the zip file):

create a TocGenerator object:
TocGenerator tocGenerator = new TocGenerator(wordMLPackage);

You can update an existing TOC by invoking updateToc.

For example:
tocGenerator.updateToc( false);

boolean skipPageNumbering argument is provided so you can control whether the helper generates indicative page numbers or not

We'll have a solution for accurate page numbers soon...

Hi Jason,

Thanks for your quick reply.

I will try out your suggestion to use "tocGenerator" and confirm if it works in my scenario soon, however accurate page numbering is quite essential to my requirements.

Do you know when do you think this is likely to be resolved please?

Thanks
Pranav

Hi Jason,

Tried the TocGenerator and getting this exception, was hoping to work straight away as per the example you suggested.

Exception loading default template "org/docx4j/convert/out/fo/docx2fo.xslt", Cannot convert argument/return type in call to method 'org.docx4j.convert.out.common.XsltCommonFunctions.notImplemented(reference, node-type, string)'
(javax.xml.transform.TransformerConfigurationException: Cannot convert argument/return type in call to method 'org.docx4j.convert.out.common.XsltCommonFunctions.notImplemented(reference, node-type, string)')

Code I am trying.

Code: Select all

   
            DocumentBuilder documentBuilder = new DocumentBuilder();
            WordprocessingMLPackage mergedWordMLPackage = documentBuilder.buildOpenDocument(blockRanges);
            TocGenerator tocGenerator = new TocGenerator(mergedWordMLPackage);
            tocGenerator.generateToc(false);
            //tocGenerator.generateToc(1, " INDEX \\e \"  \" \\c \"1\" \\z \"1033\" ", false); - eventually i would also like to add Alphabatic Index in this work document
            tocGenerator.updateToc(false);
            mergedWordMLPackage.save(baOutStream);


Thanks again for your help.

Pranav

What version of docx4j are you using?

Regarding accurate page numbering, is your use case PDF output, or something else?

[patell.pranav]

I am using docx4j 3.2.0 and Plutext 3.2.0.4 and I am generating word document files.

[jason]

What is the full stack trace please?

Do you have Xalan 2.7.1 on your classpath?

My application runs under JBOSS and i can see xalan-2.7.1.jbossorg-1.jar jar present under jboss module.

[jason]

We can't use xsltc.trax, so you shouldn't be using

org.apache.xalan.xsltc.trax.TransformerFactoryImpl

but rather

org.apache.xalan.processor.TransformerFactoryImpl

You need xalan-2.7.1.jar and serializer-2.7.1.jar

See for example
