Hi

Thanks for your inquiry.

  1. The simplest way is moving DocumentBuilder cursor to the end of list item (paragraph) and insert paragraph break. For example, see the following code:
// Open source document.
Document doc = new Document("C:\\Temp\\in.doc");
// Create DocumentBuilder.
DocumentBuilder builder = new DocumentBuilder(doc);
// We know that the last paragraph in the document is list item.
// So move corsor to the end of this paragraph.
// You can insert bookmark at the end of the list,
// and then move cursor to the bookmark.
builder.moveTo(doc.getLastSection().getBody().getLastParagraph());
// Insert paragraph break.
builder.writeln();
// Insert text of the newly inserted list item.
builder.write("This is new list item");
// Save output document.
doc.save("C:\\Temp\\out.doc");

  1. If you need to build list from scratch, you can easily achieve this using DocumentBuilder. Follow the link to learn more:

  2. Another possible situation is when you have style associated with list. In this case, you should just inset paragraph and specify the appropriate style of paragraph. In the code example, I create such style programmatically, but you might have such style already created in your document.

// Open source document.
Document doc = new Document("C:\\Temp\\in.doc");
// Create DocumentBuilder.
DocumentBuilder builder = new DocumentBuilder(doc);
// Add paragraph style asociated with list.
Style myStyle = doc.getStyles().add(StyleType.PARAGRAPH, "my style");
List myList = doc.getLists().add(ListTemplate.NUMBER_ARABIC_DOT);
myStyle.getListFormat().setList(myList);
// Insert few list items.
builder.getCurrentParagraph().getParagraphFormat().setStyle(myStyle);
builder.writeln("item 1");
builder.writeln("item 2");
builder.writeln("item 3");
builder.write("item 4");
// Save output document.
doc.save("C:\\Temp\\out.doc");
  1. You can just specify List, which paragraph belongs to, like shown in the following code example:
// Open source document.
Document doc = new Document("C:\\Temp\\in.doc");
// We know that the first paragraph is list item.
// Get List of this paragraph.
List lst = doc.getFirstSection().getBody().getFirstParagraph().getListFormat().getList();
// Add one more paragraph at the end of the document and set List.
Paragraph par = new Paragraph(doc);
par.appendChild(new Run(doc, "This is new list item."));
par.getListFormat().setList(lst);
// Insert paragraph into the document.
doc.getFirstSection().getBody().appendChild(par);
// Save output document.
doc.save("C:\\Temp\\out.doc");
