Starting to wilt a little now and the old eyes are refusing to focus properly
so I will not be able to take this any further tonight but I have managed to
make some real progress on the footer thing using XWPF.
As the basis for my experiments I used the test code - which I strongly
suspect was put together by Yegor - and managed to come up with some code
that will insert a number of different items of text into a footer. The
first wrinkle I found was that I needed to create a blank document using
Word itself and to insert a blank footer into that document (I also removed
all of the defaulted in text from the footer). Next, I used this bit of code
to open the document and insert three items of text into the footer;
public void createDocument(String documentName, String documentFolder) {
File file = null;
FileInputStream fis = null;
FileOutputStream fos = null;
XWPFDocument document = null;
XWPFHeaderFooterPolicy hfPolicy = null;
XWPFFooter footer = null;
XWPFParagraph[] footerParas = null;
XWPFParagraph para = null;
XWPFRun run = null;
try {
file = new File(documentFolder, documentName);
fis = new FileInputStream(file);
document = new XWPFDocument(fis);
hfPolicy = document.getHeaderFooterPolicy();
footer = hfPolicy.getFooter(1);
footerParas = footer.getParagraphs();
para = footerParas[0];
CTP ctP1 = para.getCTP();
CTR ctR1 = ctP1.addNewR();
CTText t = ctR1.addNewT();
t.setStringValue("Paragraph in footer");
CTR ctR2 = ctP1.addNewR();
CTText t2 = ctR2.addNewT();
t2.setStringValue("Another Run in Paragraph in footer");
CTR ctR3 = ctP1.addNewR();
CTText t3 = ctR3.addNewT();
t3.setStringValue("Yet another Run in Paragraph in footer");
XWPFParagraph p1 = new XWPFParagraph(ctP1);
XWPFParagraph[] pars = new XWPFParagraph[1];
pars[0] = p1;
hfPolicy.createFooter(XWPFHeaderFooterPolicy.DEFAULT, pars);
documentName = "Populated Footer " + documentName;
file = new File(documentFolder, documentName);
fos = new FileOutputStream(file);
document.write(fos);
}
catch(Exception ex) {
System.out.println("Caught an: " + ex.getClass().getName());
System.out.println("Message: " + ex.getMessage());
System.out.println("Localised Message: " +
ex.getLocalizedMessage());
System.out.println("Stacktrace follows:.....");
ex.printStackTrace(System.out);
}
finally {
if(fos != null) {
try {
fos.close();
}
catch(IOException ioEx) {
// I G N O R E
}
}
}
}
I need to do a lot more digging to find out how to insert new items of text
into the footer and preserve what is already there but this will have to
wait until the 'morrow I am afraid. Also, there are lots of features of the
code that I am not at all clear on yet but suspect they will come into focus
better as I experiment more. Anyway, that is all for tonight as I am off to
behave like a slob and watch a documentary about the hospital that was
constructed by the Royal Navy in the 1740's somewhere near Portsmouth, oh
and enjoy a cup of tea of course.
