That will be a problem then because HWPF - the API you will need to use to
work with the binary (OLE2CDF) files is still in development. Recently, I
tried inserting Tables into Word documents and the result was a corrupted
file. There is a method in the API - insertBefore() that promises to allow
you to insert a table, but as I said, this results I am sorry to say in a
corrupted file.
If you want to check this out for yourself, try this code;
public void insertTable(String inputFilename, String outputFilename) {
File inputFile = null;
File outputFile = null;
FileInputStream fis = null;
FileOutputStream fos = null;
HWPFDocument document = null;
Range overallRange = null;
Paragraph para = null;
TableProperties tableProps = null;
Table table = null;
try {
inputFile = new File(inputFilename);
fis = new FileInputStream(inputFile);
document = new HWPFDocument(fis);
// Get the overall Range object and try to insert a Table. This
// produced a file Word refused to open - saying it was damaged.
overallRange = document.getOverallRange();
table = overallRange.insertBefore(new TableProperties(3), 3);
// Initially, I thought the problems arose as I was working with
// the overall Range object as above. So, I got the only
Paragraph
// that I could find encapsulated by that object and tried to
// insert the Table before it - thus
//para = overallRange.getParagraph(0);
//table = para.insertBefore(new TableProperties(3), 3);
// Still the file was corrupt.
fis.close();
fis = null;
outputFile = new File(outputFilename);
fos = new FileOutputStream(outputFile);
document.write(fos);
}
catch(Exception ex) {
System.out.println("Caught an: " + ex.getClass().getName());
System.out.println("Message: " + ex.getMessage());
System.out.println("Stacktrace follows........");
ex.printStackTrace(System.out);
}
finally {
if(fis != null) {
try {
fis.close();
fis = null;
}
catch(IOException ioEx) {
// I G N O R E
}
}
if(fos != null) {
try {
fos.close();
fos = null;
}
catch(IOException ioEx) {
// I G N O R E
}
}
}
}
You will notice that there two filenames passed to this method. The first is
the path to an name of an emprty Word document that I created using Word
itself as I do not think that HWPF can yet generate a brand new document
itself - the no-arg constructor for the HWPFDocument class is protected.
