I don't understand it ... changing to java6 didn't solve it. I set up a new
virtual machine Xubuntu and installed openjdk6 and netbeans from
repository. I changed nothing, I'm only running these lines

    public static void main(String[] args) throws IOException {

        HSSFWorkbook wb = new HSSFWorkbook();
        FileOutputStream fileOut = new
FileOutputStream("/home/muench/workbook_test.xls");
        wb.write(fileOut);
        fileOut.close();
    }

But opening the xls under Windows with Microsoft Office it shows the same
behaviour ... I don't know how to continue :/
