Docx to Pdf Converter in java

Question

The below code is not working with Apache poi 3.16. Can someone provide with the correct solution, in my project there are some dependency for using only

public void ConvertToPDF(String docPath, String pdfPath) {
    try {
        InputStream doc = new FileInputStream(new File(docPath));
        XWPFDocument document = new XWPFDocument(doc);
        PdfOptions options = PdfOptions.create();
        OutputStream out = new FileOutputStream(new File(pdfPath));
        PdfConverter.getInstance().convert(document, out, options);
        System.out.println("Done");
    } catch (FileNotFoundException ex) {
        System.out.println(ex.getMessage());
    } catch (IOException ex) {
        System.out.println(ex.getMessage());
    }
}

Exception:

Answer 1

November 2023: Works using apache poi version 5.2.2 and the newest version 2.0.4 of fr.opensagres.poi.xwpf.converter.pdf and consorts.

Answer 2

The main problem with this is that those PdfOptions and PdfConverter are not part of the apache poi project. They are developed by opensagres and first versions were badly named org.apache.poi.xwpf.converter.pdf.PdfOptions and org.apache.poi.xwpf.converter.pdf.PdfConverter. Those old classes were not updated since 2014 and needs version 3.9 of apache poi to be used.

Do using the much more current fr.opensagres.poi.xwpf.converter.pdf, which works using the latest stable release apache poi 3.17.

Then do

import java.io.InputStream;
import java.io.OutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.File;

//needed jars: fr.opensagres.poi.xwpf.converter.core-2.0.1.jar, 
//             fr.opensagres.poi.xwpf.converter.pdf-2.0.1.jar,
//             fr.opensagres.xdocreport.itext.extension-2.0.1.jar,
//             itext-2.1.7.jar                                  
import fr.opensagres.poi.xwpf.converter.pdf.PdfOptions;
import fr.opensagres.poi.xwpf.converter.pdf.PdfConverter;

//needed jars: apache poi and it's dependencies
import org.apache.poi.xwpf.usermodel.XWPFDocument;

public class DOCXToPDFConverterSampleMin {

 public static void main(String[] args) throws Exception {

  String docPath = "./WordDocument.docx";
  String pdfPath = "./WordDocument.pdf";

  InputStream in = new FileInputStream(new File(docPath));
  XWPFDocument document = new XWPFDocument(in);
  PdfOptions options = PdfOptions.create();
  OutputStream out = new FileOutputStream(new File(pdfPath));
  PdfConverter.getInstance().convert(document, out, options);

  document.close();
  out.close();

 }
}

October 2018: This code works using apache poi 3.17. It cannot work using apache poi 4.0.0 due to changings in apache poi which were not taken in account in fr.opensagres.poi.xwpf.converter until now.

---

February 2019: Works for me now using the newest apache poi version 4.0.1 and the newest version 2.0.2 of fr.opensagres.poi.xwpf.converter.pdf and consorts.

---

June 2021: Works using apache poi version 4.1.2 and the newest version 2.0.2 of fr.opensagres.poi.xwpf.converter.pdf and consorts. Cannot work using apache poi version 5.0.0 because XDocReport needs ooxml-schemas which apache poi 5 does not support anymore.

---

April 2022: Works using apache poi version 5.2.2 and the newest version 2.0.3 of fr.opensagres.poi.xwpf.converter.pdf and consorts.

---

July 2023: Works using apache poi version 5.2.3 and the newest version 2.0.4 of fr.opensagres.poi.xwpf.converter.pdf and consorts.

Answer 3

June 2021: Works using apache poi version 4.1.2 and the newest version 2.0.2 of fr.opensagres.poi.xwpf.converter.core and consorts. Cannot work using apache poi version 5.0.0 because XDocReport needs ooxml-schemas which apache poi 5 does not support anymore.

ooxml-schemas has been replaced with poi-ooxml-full.

https://mvnrepository.com/artifact/org.apache.poi/poi-ooxml-full/5.0.0

but it doesn't work with fr.opensagres.poi.xwpf.converter.core 2.0.2, because is not compatible with new version of CTStyle which is included in apache-poi 5.0.0.

Answer 4

Just addded in POX.xml

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>4.0.0</version>
</dependency>
<dependency>
    <groupId>fr.opensagres.xdocreport</groupId>
    <artifactId>fr.opensagres.poi.xwpf.converter.pdf</artifactId>
    <version>2.0.2</version>
</dependency>

Answer 5

New version 2.0.2 of fr.opensagres.poi.xwpf.converter.core runs with apache poi 4.0.1 and itext 2.17. You just need to add below dependency in Maven and then maven will auto download all dependent dependencies. (Updated your Maven project, so it downloaded all these libraries and all of its dependencies)

<dependency>
    <groupId>fr.opensagres.xdocreport</groupId>
    <artifactId>fr.opensagres.poi.xwpf.converter.pdf</artifactId>
    <version>2.0.2</version>
</dependency>
