merge document error

[giuseppe]

Hi to all,

I want to merge some file docx into a new one. These files may contains images.
This is my code.

File first = new File("C:\\...\\...\\main.docx");
File second = new File("C:\\...\\...\\attach_1.docx");
File third = new File("C:\\...\\...\\attach_2.docx");
File fourth = new File("C:\\...\\...\\attach_3.docx");

try
{
WordprocessingMLPackage cdu = WordprocessingMLPackage.load(new FileInputStream(first));

org.docx4j.wml.P p = new org.docx4j.wml.P();
org.docx4j.wml.R r = new org.docx4j.wml.R();
org.docx4j.wml.Br br = new org.docx4j.wml.Br();

br.setType(STBrType.PAGE);
r.getContent().add(br);
p.getContent().add(r);
cdu.getMainDocumentPart().addObject(p);

List<WordprocessingMLPackage> attachmentList = new ArrayList<WordprocessingMLPackage>();

attachmentList.add(WordprocessingMLPackage.load(new FileInputStream(second)));
attachmentList.add(WordprocessingMLPackage.load(new FileInputStream(second)));
attachmentList.add(WordprocessingMLPackage.load(new FileInputStream(third)));
attachmentList.add(WordprocessingMLPackage.load(new FileInputStream(fourth)));

int numAttach = attachmentList.size();

// cycle on attachment
for (int idx=0; idx<numAttach; idx++)
{
WordprocessingMLPackage attach = attachmentList.get(idx);

List<Object> blips = attach.getMainDocumentPart().getJAXBNodesViaXPath("//a:blip", false);

for(Object el : blips)
{
try
{
CTBlip blip = (CTBlip) el;

RelationshipsPart parts = attach.getMainDocumentPart().getRelationshipsPart();
Relationship rel = parts.getRelationshipByID(blip.getEmbed());

RelationshipsPart cduRels = cdu.getMainDocumentPart().getRelationshipsPart();

rel.setId(null);
cduRels.addRelationship(rel);
blip.setEmbed(rel.getId());

PartName pn = new PartName("/word/"+rel.getTarget());

Part part = attach.getParts().getParts().get(pn);

Relationship newRel = cdu.getMainDocumentPart().addTargetPart(part, AddPartBehaviour.RENAME_IF_NAME_EXISTS);
}
catch (Exception ex) {}
}

List<Object> body = attach.getMainDocumentPart().getJAXBNodesViaXPath("//w:body", false);

for(Object b : body)
{
List filhos = ((org.docx4j.wml.Body)b).getContent();

for(Object k : filhos)
cdu.getMainDocumentPart().addObject(k);
}
}

File saved = new File("C:\\...\\saved.docx");
cdu.save(saved);
}
catch (Docx4JException e) {
e.printStackTrace();
}
catch (JAXBException e1) {
e1.printStackTrace();
}
catch (FileNotFoundException e) {
e.printStackTrace();
}

I have an exception when I save merged doc:

org.docx4j.openpackaging.exceptions.Docx4JException: Failed to add parts from relationships of /

image12.png is generated by cdu.getMainDocumentPart().addTargetPart(part, AddPartBehaviour.RENAME_IF_NAME_EXISTS)

this method return a Relationship (newRel), but I can't find the way to use it.
Anyone has some ideas? I have some difficulty to find documentation about this.
Thanks.

You need to move or copy the relevant part to the target package, so it can be found by saveBinaryPart

Hi Jason,

thanks for the response, but I'm afraid I don't understand your suggestion.
Could you indicate me some examples or some documentation/guide about this?
Thanks a lot.
Giuseppe

You can examine the saving code to see what it is looking for, but basically:

- a package knows which parts it contains https://github.com/plutext/docx4j/blob/ ... .java#L114 so you need to add the part here

- a part can also know which package it is in https://github.com/plutext/docx4j/blob/ ... .java#L217
