Some HWPF POI document building examples

Question

I'm looking for examples of building non-trivial Word (97-2003) documents with POI. I already reached to create one with "Hello World":

package com.mygroup.myapp.poi.word;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.net.URL;

import org.apache.log4j.Logger;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.usermodel.CharacterRun;
import org.apache.poi.hwpf.usermodel.Range;

public class DocFileWriter {

    private static final Logger LOGGER = Logger.getLogger(DocFileWriter.class);
    private static final String FILE_EXTENSION = ".doc";
    private static final URL EMPTY_DOC_URL = DocFileWriter.class.getClassLoader().getResource("empty.doc");
    private String pathname;
    private HWPFDocument document;

    /**
     * Constructor
     * @param pathname the target path name (e.g.: "/tmp/test.doc", etc.)
     * @throws IOException 
     */
    public DocFileWriter(String pathname) throws IOException {
        if (!pathname.endsWith(FILE_EXTENSION)) {
            throw new RuntimeException("The file name must ends with " + FILE_EXTENSION);
        }
        this.pathname = pathname;
        try {
            document = new HWPFDocument(EMPTY_DOC_URL.openStream());
        } catch (IOException e) {
            LOGGER.error("Empty document resource missing");
            throw e;
        }
    }


    /**
     * Adds a "Hello World!" to the document.
     */
    public void addHelloWorld() {
        Range range = document.getRange();
        CharacterRun charRun = range.insertBefore("Hello World!");
        charRun.setFontSize(18);
        charRun.setItalic(true);
    }

    /**
     * Writes the document on disk.
     */
    public void writeDocument() {
        try {
            document.write(new FileOutputStream(new File(pathname)));
        } catch (FileNotFoundException e) {
            LOGGER.error("The file cannot be created", e);
        } catch (IOException e) {
            LOGGER.error("Unable to write the document", e);
        }
    }
}

Now I'd like to add:

  • a picture
  • a blank page
  • a header (only one string)
  • a footer (only one string)
  • a table (10 rows, 3 columns)

Would you have some pointers/examples about that?

Thank you.

Was it helpful?

Solution

As indicated here HWPF is an orphan subproject of POI. There's no way to write complex old .doc files from scratch. Adding pictures/headers/footers/tables is only managed by XWPF and .docx format.

So I chose to use RTF (with a .doc extension). Here are some solution to build RTF reports:
