Merging docx with Shape "at the end" of the document

We have the following two documents:

And

I merge both documents to one PDF file.

The result looks like this:

As you can see, the content of the second document is inside of the shape of the first document.

I use the following code to merge documents:

public Document mergeDocuments(List<Document> documents) {
        Document result = null;
        DocumentBuilder builder = null;

        for(Document document : documents){
            if(result == null){
                result = document;
                builder = new DocumentBuilder(result);
            }
            else {
                builder.moveToDocumentEnd();
                builder.insertBreak(BreakType.PAGE_BREAK);
//                document.getFirstSection().getPageSetup().setRestartPageNumbering(false);
//                builder.getDocument().getFirstSection().getPageSetup().setRestartPageNumbering(true);
                builder.insertDocument(document, ImportFormatMode.KEEP_DIFFERENT_STYLES, getImportFormatOptions());
            }
        }
        return result;
    }

And then save it to PDF with the following code:

public byte[] writeFile(Document document, String fileExtension) throws IOException {

        try (ByteArrayOutputStream outputStream = new ByteArrayOutputStream()) {
            SaveOptions saveOptions = SaveOptions.createSaveOptions(SaveFormat.fromName(fileExtension.toUpperCase()));
            if(saveOptions instanceof PdfSaveOptions pdfSaveOptions){
                pdfSaveOptions.setPreserveFormFields(true);
                pdfSaveOptions.setUpdateFields(true);
            }
            document.getFieldOptions().setFieldUpdateCultureSource(FieldUpdateCultureSource.FIELD_CODE);
            document.save(outputStream, saveOptions);

            return outputStream.toByteArray();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

Attached the input and output file(s):

template-1.docx (20.3 KB)

template-2.docx (17.8 KB)

@kerner You should use Document.appendDocument method instead of DocumentBuilder.insertDocument method to merge documents. Please try using the following code:

Document doc1 = new Document("C:\\Temp\\template-1.docx");
Document doc2 = new Document("C:\\Temp\\template-2.docx");
doc1.appendDocument(doc2, ImportFormatMode.KEEP_DIFFERENT_STYLES);
doc1.save("C:\\Temp\\out.docx");

I changed the code to the following:

 public Document mergeDocuments(List<Document> documents) {
        Document result = null;

        for(Document document : documents){
            if(result == null){
                result = document;
            }
            else {
                DocumentBuilder builder = new DocumentBuilder(result);
                builder.moveToDocumentEnd();
                builder.insertBreak(BreakType.PAGE_BREAK);
                result.appendDocument(document, ImportFormatMode.KEEP_DIFFERENT_STYLES);
            }
        }
        return result;
    }

Merging works fine now, thank you! But the page break is not inserted anymore. How can I insert a Page break between each document?

@kerner It is not required to insert a page break. You can simply set section start to new page:

Document doc1 = new Document("C:\\Temp\\template-1.docx");
Document doc2 = new Document("C:\\Temp\\template-2.docx");
// Set section start for the first section of second document to new page.
doc2.getFirstSection().getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
doc1.appendDocument(doc2, ImportFormatMode.KEEP_DIFFERENT_STYLES);
doc1.save("C:\\Temp\\out.docx");
