Please help me i have to finish this job today itself.

File newFile = new File("C:\\Documents and Settings\\z003363\\Desktop\\vel.doc");
		//HWPFDocument doc = new HWPFDocument(new FileInputStream(newFile));
		POIFSFileSystem fs = new POIFSFileSystem(new FileInputStream(newFile));
		HWPFDocument doc = new HWPFDocument(fs);
		Range range = doc.getRange();
		CharacterRun run = range.insertAfter("Hello World!!!GGGGG");
		run.setBold(true);
		run.setItalic(true);
		run.setCapitalized(true);
		OutputStream outa = new FileOutputStream(newFile);

Welcome to the Ranch

I have added code tags to your code, and you can see how much better it looks. Why are you not closing the file output stream in a finally block? Why are you calling flush(); I thought you did not need that.
Don’t know about the Exception; there are no obvious arrays in your code, unless there is an array in the insertAfter method. Are you sure it is the code you posted which is causing that Exception? Unless insertAfter requires an array, which has 23 elements or fewer, I can’t see where the Exception came from.

Thank you for your Precious and quick reply Ritchie.

Actually my requirement is to create word 2003 format document using apache poi.Please let me know what changes need to be done in the above code.Also post your suggestions for creating word 2003 document.I have to create table in the document.

Well your exception appears to be occurring in the constructor itself.

Why, I don't know - I'm no POI expert - but one possibility is that the file doesn't exist. Have you checked this?

It also seems an odd way to create a document (ie, from a class that appears to refer to a file system, rather than a file or stream). Have you tried creating it directly from the input stream itself? HWPFDocument seems to allow you to do that but, as I say, I'm no expert.

Thank you winston.

I verified and confirmed file existance.Is there anybody know poi very well please help to come out of the error.Its very urgent.

Thank you WP for your reply.

This is the new program i tried and i got the word document with the given word.But how to
display table inside word.I know how to create table using XWPFDocument but that will not work
in MSWord 2003.so i want yours help.

public class SampleProject {

	/**
	 * @param args
	 */
	static void writeToFile(String content, String path){
		// TODO Auto-generated method stub
		try{
		POIFSFileSystem fs = new POIFSFileSystem();
		DirectoryEntry directory = fs.getRoot();
		directory.createDocument("WordDocument", new ByteArrayInputStream(content.getBytes()));
		FileOutputStream out = new FileOutputStream(path);
		fs.writeFilesystem(out);
		out.close();
		}
		catch(Exception ex) {
		System.out.println(ex.getMessage());
		ex.printStackTrace();
		                }
		        }
		                public static void main(String[]args){
		                writeToFile("Hello World to word","C:\\Documents and Settings\\sample\\Desktop\\vel.doc");
		                
		                }
	}

I doubt that this is the correct approach to create documents. I think it's more likely that DirectoryEntry and its methods deal with content inside of a file, rather than files inside of a file system. Your first approach looks better to me.

Thank you for your reply.

I got this exception

Exception in thread "main" java.lang.NullPointerException

So you have a NPE to track down and fix. You can remove anything related to document properties from this example if it's not relevant to your code.

[velMurugan vasu]

Thank you for your reply

I comment the code from 46 to 51 then the program runs successfully but i got the empty document as output.
you have any sample code to generate table.

[Tim Moores]

POI's API is complex, and not much documentation is available. You need to be prepared to spend time with the javadocs and for some experimentation. Here's some code you could try:

int rows = 2;
int columns = 2;

Range range = doc.getRange();
Table table = range.insertBefore(new TableProperties(columns), rows);

for (int rowIdx=0; rowIdx<table.numRows(); rowIdx++) {
	TableRow row = table.getRow(rowIdx);
	for (int colIdx=0; colIdx<row.numCells(); colIdx++) {
		TableCell cell = row.getCell(colIdx);
		try {
			Paragraph par = cell.getParagraph(0);
			par.insertBefore(""+(rowIdx*row.numCells()+colIdx));
		} catch (Exception ex) {
			ex.printStackTrace();
		}
	}
}

Once you figure out how to add tables, that would be a good addition for you to add to that example code

[velMurugan vasu]

Hi Tim Moores Thanks alot for your example code and i fixed the issue thanks again for your code.
