Hi,
I've a problem using POI with java.
Sometimes when I want to open a worddoc to get its content it doesn't work.
I get a NullPointerException looking like this one:
java.lang.NullPointerException

On some document it works without any problems, but on some specific ones it
just doesn't work. I can't find any equality in the word docs on which it
doesn't work. Maybe someone of you has had a similar problem before and knows
why this exception appears?!
Here is a code example with which I'm trying to get the content of the word
doc:
try {
fis = new FileInputStream(worddoc); // worddoc is the word-file
doc = new WordDocument(fis);
doc.openDoc(); //open the document
swriter = new StringWriter(); //construct a swriter since
WogrdDocument.writeAllText needs a writer
//dump the document-text to our swriter to see if HDF works basically
doc.writeAllText(swriter);
content = swriter.toString();
}
catch (IOException e) {
e.printStackTrace();
}
I hope someone can help me
thx Amr�n
