Hello

I am trying to use poi to extract the text of some word documents with the
following code
StringWriter writer = new StringWriter();
WordDocument doc = new WordDocument("C:\\arj\\pdf\\peer.doc");
doc.openDoc();
doc.writeAllText(writer);
System.out.println(writer.toString());
some word files respond with the following exception
java.lang.NullPointerException
