This is the first time I am working on Apache POI and the question which I am going to ask has been asked already on this site but no clear answer were given for them so I have no choice but to take all your help.
I am trying to write a java program which takes images from one folder and insert that image into a word document. I am using Apache POI for this program. Here I am posting my code.
import java.io.*;
import java.util.*;
import org.apache.poi.util.IOUtils;
import org.apache.poi.xwpf.usermodel.*;
public class ImagesDoc
{
public static void main(String[] args) throws IOException
{
XWPFDocument docx = new XWPFDocument();
XWPFParagraph par = docx.createParagraph();
XWPFRun run = par.createRun();
run.setText("Hello, World. This is my first java generated docx-file. Have fun.");
run.setFontSize(13);
InputStream pic = new FileInputStream("C:\\Users\\amitabh\\Pictures\\pics\\pool.jpg");
byte [] picbytes = IOUtils.toByteArray(pic);
docx.addPicture(picbytes, Document.PICTURE_TYPE_JPEG);
FileOutputStream out = new FileOutputStream("C:\\Users\\amitabh\\Pictures\\pics\\simple1.docx");
docx.write(out);
out.close();
pic.close();
}
}
I am able to create the word document file and I am able to insert the text as well but docx.addPicture(picbytes, Document.PICTURE_TYPE_JPEG); line is giving me the error as"add cast to docx". I have added all possible jars for this program. For this error I have searched all over the net and found that many people are having similar problem. "addPicture" for XWPFDocument reference is not working. Please help me to resolve this problem.

First, I would like to point out the example provided by apache poi - Link, i.e. the correct way to do it would be
doc.createParagraph().createRun().addPicture(new FileInputStream(imgFile), format, imgFile, Units.toEMU(200), Units.toEMU(200));
However, there is still an existing bug which renders the .docx file unreadable after executing the above statement. It might be resolved soon, in which case the above-mentioned statement will do the work. For the meantime, there is a work-around.
First, generate the docx file without any pictures. Then add this class CustomXWPFDocument to your package.
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\">" +
" <a:graphicData uri=\"http://schemas.openxmlformats.org/drawingml/2006/picture\">" +
" <pic:pic xmlns:pic=\"http://schemas.openxmlformats.org/drawingml/2006/picture\">" +
" <pic:nvPicPr>" +
" <pic:cNvPr id=\"" + id + "\" name=\"Generated\"/>" +
" <pic:cNvPicPr/>" +
" </pic:nvPicPr>" +
" <pic:blipFill>" +
" <a:blip r:embed=\"" + blipId + "\" xmlns:r=\"http://schemas.openxmlformats.org/officeDocument/2006/relationships\"/>" +
" <a:stretch>" +
" <a:fillRect/>" +
" </a:stretch>" +
" </pic:blipFill>" +
" <pic:spPr>" +
" <a:xfrm>" +
" <a:off x=\"0\" y=\"0\"/>" +
" <a:ext cx=\"" + width + "\" cy=\"" + height + "\"/>" +
" </a:xfrm>" +
" <a:prstGeom prst=\"rect\">" +
" <a:avLst/>" +
" </a:prstGeom>" +
" </pic:spPr>" +
" </pic:pic>" +
" </a:graphicData>" +
"</a:graphic>";
//CTGraphicalObjectData graphicData = inline.addNewGraphic().addNewGraphicData();
XmlToken xmlToken = null;
try
{
xmlToken = XmlToken.Factory.parse(picXml);
}
catch(XmlException xe)
{
xe.printStackTrace();
}
inline.set(xmlToken);
//graphicData.set(xmlToken);
inline.setDistT(0);
inline.setDistB(0);
inline.setDistL(0);
inline.setDistR(0);
CTPositiveSize2D extent = inline.addNewExtent();
extent.setCx(width);
extent.setCy(height);
CTNonVisualDrawingProps docPr = inline.addNewDocPr();
docPr.setId(id);
docPr.setName("Picture " + id);
docPr.setDescr("Generated");
}
}
Then, create the updated document by adding your pictures like this :-
CustomXWPFDocument document = new CustomXWPFDocument(new FileInputStream(new File("C:\\Users\\Avarice\\Desktop\\doc1.docx")));
FileOutputStream fos = new FileOutputStream(new File("C:\\Users\\Avarice\\Desktop\\doc2.docx"));
String id = document.addPictureData(new FileInputStream(new File("C:\\Users\\Avarice\\Desktop\\thumbnail.jpg")), Document.PICTURE_TYPE_JPEG);
document.createPicture(id,document.getNextPicNameNumber(Document.PICTURE_TYPE_JPEG), 64, 64);
document.write(fos);
fos.flush();
fos.close();
You should also have the following jars in your build path:-
poi-ooxml-schemas
xmlbeans
dom4j

I have used poi 3.10 to generate word doc and to insert a picture. you need 2 classes.. here is the example
