Replacing variables in a word document template with java

Question

I want to load a template word document to add content to and save as new document. I\'m working on .doc file.

After a long research I only found solutions for docx

Answer 1

Recently I had to solve the same problem but with a .docx document. And trying the approach above resulted as the following error (As reported in this post):

org.apache.poi.poifs.filesystem.OfficeXmlFileException: The supplied data appears to be in the Office 2007+ XML. You are calling the part of POI that deals with OLE2 Office Documents. You need to call a different part of POI to process this data (eg XSSF instead of HSSF)

Finally, I had to change the code as follow (in my case the .docx file is inside the resource folder):

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.net.URISyntaxException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import org.apache.poi.xwpf.usermodel.XWPFDocument;

public class XWPFTest {

    public static void main(String[] args) throws URISyntaxException, IOException {
        String resourcePath = "template.docx";
        Path templatePath = Paths.get(XWPFTest.class.getClassLoader().getResource(resourcePath).toURI());
        XWPFDocument doc =  new XWPFDocument(Files.newInputStream(templatePath));
        doc = replaceTextFor(doc, "UNIQUE_VAR", "MyValue1");
        saveWord("C:\\document.docx", doc);
    }

    private static XWPFDocument replaceTextFor(XWPFDocument doc, String findText, String replaceText){
        doc.getParagraphs().forEach(p ->{
            p.getRuns().forEach(run -> {
                String text = run.text();
                if(text.contains(findText)) {
                    run.setText(text.replace(findText, replaceText), 0);
                } 
            });
        });

        return doc;
    }

    private static void saveWord(String filePath, XWPFDocument doc) throws FileNotFoundException, IOException{
        FileOutputStream out = null;
        try{
            out = new FileOutputStream(filePath);
            doc.write(out);
        }
        catch(Exception e) {
            e.printStackTrace();
        }
        finally{
            out.close();
        }
    }

}

P.S. I had to remove the $ because in .docx are managed are separate runs so I had to opt for the approach of a unique var name. I needed the following Apache POI dependencies:

    org.apache.poi
    poi
    3.17


    org.apache.poi
    poi-ooxml
    3.17


    org.apache.poi
    poi-scratchpad
    3.17
