I am trying to delete a paragraph from the .docx document i have generated using the Apache poi XWPF. I can do it easily with the .doc word document using HWPF as below :

    for (String paraCount : plcHoldrPargrafDletdLst) {
        Paragraph ph = doc.getRange().getParagraph(Integer.parseInt(paraCount));
        System.out.println("Deleted Paragraph Start & End: " + ph.getStartOffset() +" & " + ph.getEndOffset());
        System.out.println("Deleted Paragraph Test: " + ph.text());
        ph.delete();
I tried to do the same with 
doc.removeBodyElement(Integer.parseInt(paraCount));
But unfortunatley not successful enough to get the result as i want. The result document, i cannot see the paragraph deleted.

Any suggestions on how to accompolish the similar functionality in XWPF.
Ok, this question is a bit old and might not be required anymore, but I just found a different solution than the suggested one.
Hope the following code will help somebody with the same issue
    FileInputStream fis = new FileInputStream(fileName);
    XWPFDocument doc = new XWPFDocument(fis);
    fis.close();
    // Find a paragraph with todelete text inside
    XWPFParagraph toDelete = doc.getParagraphs().stream()
            .filter(p -> StringUtils.equalsIgnoreCase("todelete", p.getParagraphText()))
            .findFirst().orElse(null);
    if (toDelete != null) {
        doc.removeBodyElement(doc.getPosOfParagraph(toDelete));
        OutputStream fos = new FileOutputStream(fileName);
        doc.write(fos);
        fos.close();

Java – how to add a picture to a .docx document with Apache POI XWPF in java

I know this post is very old but still I am posting the answer so that all those who are searching for this answer can use it.
For inserting the picture in the word document you have to write two programs. The first one is :-
package org.word.POI;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.poi.openxml4j.exceptions.InvalidFormatException;
import org.apache.poi.xwpf.usermodel.Document;
import org.apache.poi.xwpf.usermodel.XWPFDocument;

public class TestCustom
    public static void main(String []a) throws FileNotFoundException, IOException, InvalidFormatException
        CustomXWPFDocument document = new CustomXWPFDocument(new FileInputStream(new File("C:\\Users\\amitabh\\Documents\\Apache POI\\Word File\\new.doc")));
        FileOutputStream fos = new FileOutputStream(new File("C:\\Users\\amitabh\\Documents\\Apache POI\\Word File\\new.doc"));
        String blipId = document.addPictureData(new FileInputStream(new File("C:\\Users\\amitabh\\Pictures\\pics\\3.jpg")), Document.PICTURE_TYPE_JPEG);
        System.out.println(document.getNextPicNameNumber(Document.PICTURE_TYPE_JPEG));
        //System.out.println(document.getNextPicNameNumber(Document.PICTURE_TYPE_JPEG));
        document.createPicture(blipId,document.getNextPicNameNumber(Document.PICTURE_TYPE_JPEG), 500, 500);
        document.write(fos);
        fos.flush();
        fos.close();
Now here I have used "CustomeXwPFDocument" in this code and you will not get any imports through any jar file so you have to add another .java class in your package. the code for "CustomXWPFDocument" class goes like this:-
package org.word.POI;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.xmlbeans.XmlException;
import org.apache.xmlbeans.XmlToken;
import org.openxmlformats.schemas.drawingml.x2006.main.CTNonVisualDrawingProps;
import org.openxmlformats.schemas.drawingml.x2006.main.CTPositiveSize2D;
import org.openxmlformats.schemas.drawingml.x2006.wordprocessingDrawing.CTInline;
import java.io.IOException;
import java.io.InputStream;
public class CustomXWPFDocument extends XWPFDocument
    public CustomXWPFDocument(InputStream in) throws IOException
        super(in);
    public void createPicture(String blipId,int id, int width, int height)
        final int EMU = 9525;
        width *= EMU;
        height *= EMU;
        //String blipId = getAllPictures().get(id).getPackageRelationship().getId();
        CTInline inline = createParagraph().createRun().getCTR().addNewDrawing().addNewInline();
        String picXml = "" +
                "<a:graphic xmlns:a=\"http://schemas.openxmlformats.org/drawingml/2006/main\">" +

                "         <pic:spPr>" +
                "            <a:xfrm>" +

                "         </pic:spPr>" +
                "      </pic:pic>" +
                "   </a:graphicData>" +
                "</a:graphic>";
        //CTGraphicalObjectData graphicData = inline.addNewGraphic().addNewGraphicData();
        XmlToken xmlToken = null;
            xmlToken = XmlToken.Factory.parse(picXml);
        catch(XmlException xe)
            xe.printStackTrace();
        inline.set(xmlToken);
        //graphicData.set(xmlToken);

        docPr.setId(id);
        docPr.setName("Picture " + id);
        docPr.setDescr("Generated");
Use POI 3.9 jars for this program. The best URL is:-

Now you are ready to fly. Best of luck.
    
Java – Replacing a text in Apache POI XWPF

The method you need is XWPFRun.setText(String). Simply work your way through the file until you find the XWPFRun of interest, work out what you want the new text to be, and replace it. (A run is a sequence of text with the same formatting)
You should be able to do something like:
XWPFDocument doc = new XWPFDocument(OPCPackage.open("input.docx"));
for (XWPFParagraph p : doc.getParagraphs()) {
    List<XWPFRun> runs = p.getRuns();
    if (runs != null) {
        for (XWPFRun r : runs) {
            String text = r.getText(0);
            if (text != null && text.contains("needle")) {
                text = text.replace("needle", "haystack");
                r.setText(text, 0);
for (XWPFTable tbl : doc.getTables()) {
   for (XWPFTableRow row : tbl.getRows()) {
      for (XWPFTableCell cell : row.getTableCells()) {
         for (XWPFParagraph p : cell.getParagraphs()) {
            for (XWPFRun r : p.getRuns()) {
              String text = r.getText(0);
              if (text != null && text.contains("needle")) {
                text = text.replace("needle", "haystack");
                r.setText(text,0);
doc.write(new FileOutputStream("output.docx"));
