HWPF POI

[Rishi Kanth]

Hey All,

I have previously used Apache POI to generate XL reports. I am trying to use the POI for generating word reports. I am able to read the word document using HWPFDocument and POIFS input stream. How can I obtain the formating of the paragraph or words. if I have for example, Hello. How can I know that the read word from the document "Hello" is bold.

Thanks,

From all Range objects (like Paragraphs) you can obtain a list of CharacterRun objects for that Range - those have style information associated with them.

Hey

Thanks for the reply. I was able to get the properties of the CharacterRun/Paragraph. I am having trouble rreading/writing Tables to the word document.
Currently I am using the following code to get the Table, but its throwing an exception

Range r = doc.getRange();
for(int i = 0;i<r.numSections();i++)
{
	Section s = r.getSection(i);
	for(int j=0;j<s.numParagraphs();j++)
	{
              Paragraph p = s.getParagraph(j);
              String ps = p.text();
              if(p.isInTable())
              {
                     System.out.println("Table");
	              Table t = r.getTable(p);
		}
}}

I get the following exception

java.lang.IllegalArgumentException: This paragraph is not a child of this range
	at org.apache.poi.hwpf.usermodel.Range.getTable(Range.java:863)
	at WordTest.generateReport(WordTest.java:59)
	at WordTest.main(WordTest.java:85)

Can someone please help me to read/write tables and image to the DOC using POI.

Thanks,>

Not sure what's happening, but here's some code I used to examine tables which worked fine as I recall.

import java.io.*;
import java.util.*;

import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.model.*;
import org.apache.poi.hwpf.usermodel.*;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;

public class TableTest {

    public static void main (String[] args) throws Exception {
		String fileName = "table.doc";

		if (args.length > 0) {
			fileName = args[0];
		}

		InputStream fis = new FileInputStream(fileName);
		POIFSFileSystem fs = new POIFSFileSystem(fis);
		HWPFDocument doc = new HWPFDocument(fs);

		Range range = doc.getRange();

		for (int i=0; i<range.numParagraphs(); i++) {
			Paragraph par = range.getParagraph(i);
			System.out.println("paragraph "+(i+1));
			System.out.println("is in table: "+par.isInTable());
			System.out.println("is table row end: "+par.isTableRowEnd());
			System.out.println(par.text());
		}

		Paragraph tablePar = range.getParagraph(0);
		if (tablePar.isInTable()) {
			Table table = range.getTable(tablePar);
			for (int rowIdx=0; rowIdx><table.numRows(); rowIdx++) {
				TableRow row = table.getRow(rowIdx);
				System.out.println("row "+(rowIdx+1)+", is table header: "+row.isTableHeader());
				for (int colIdx=0; colIdx><row.numCells(); colIdx++) {
					TableCell cell = row.getCell(colIdx);
					System.out.println("column "+(colIdx+1)+", text="+cell.getParagraph(0).text());
				}
			}
		}
    }
}

Note that working with HWPF tables is buggy: https://issues.apache.org/bugzilla/show_bug.cgi?id=47563

Hi to all,
Is there any chance to get and set an Tables and Images height ,width and position in a word document(.doc and .docx format) by using POI jar....?
Please suggest possibilities.

I'm not sure what you mean by "position in a document", but image width and height are available through the org.apache.poi.hwpf.usermodel.Picture class. Curiously, it doesn't seem to have an XWPF equivalent.
