Only just begun to have a play with XWPF but it already seems much more
'solid' that HWPF as the latter is sorely in need of talented developers to
help move it on (not too subtle hint there in case you missed it).
However, the news on footers - and on headers for that matter - is still not
too good. The XWPFDocument class defines a method that allows you to recover
the documents associated XWPFHeaderFooterPolicy object. That object is
responsibile for managing the documents headers and footers and it contains
method that allow you to create a new footer, recover a reference to a
footer and to then modify that. The only problem I have run in to yet is
that I cannot get at this object the XWPFHeaderFooterPolicy that is. So far,
I have tried to call the gerHeaderFooterPolicy() on an XWPFDocument that I
had previously created in the code and a null value was returned. Thinking
about HWPF and the typical idion we use there when getting cells, I though
that I should test the returned value and if it was null, then reate a new
instance of the XWPFHeaderFooterPolicy class. This still did not work and
the code still threw a NullPointerException. Finally, I though I would
create a blank document using Word and insert a footer into that, planning
to open it using POI and then get the header/footer policy and so on from
there. However, now an exception was thrown when I tried to create an
instance of the XWPFDocument class, this time the message concerned a null
XWPFHeaderFooterPolicy object - surprise!
So, the next thing I am going to try is to download the very latest release
of the software and try that. As always, I will keep you updated if I make
any progress. If you want to follow in my footsteps so to speak, this is the
scruffy test code I have been playing around with;
import org.apache.poi.xwpf.usermodel.*;
import org.apache.poi.xwpf.model.*;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
/**

*/
public class Main {
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 {
document = new XWPFDocument();
para = document.createParagraph();
run = para.createRun();
run.setText("This should contain the text for the first XWPFRun
" +
"in the newly created Paragraph.");
run.setBold(true);
run = para.createRun();
run.setText("It is my hope that this XWPFRun will contain the "
+
"text for the second paragraph that I have just added -
" +
"with luck - to the newly created document.");
hfPolicy = document.getHeaderFooterPolicy();
if(hfPolicy == null) {
hfPolicy = new XWPFHeaderFooterPolicy(document);
}
hfPolicy.createFooter(
rg.openxmlformats.schemas.wordprocessingml.x2006.main.STHdrFtr.Enum.forString("Footer."));
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("Stacktrace follows:.....");
ex.printStackTrace(System.out);
}
finally {
if(fos != null) {
try {
fos.close();
}
catch(IOException ioEx) {
// I G N O R E
}
}
}
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
new Main().createDocument("New XWPF Document.docx", "C:/temp");
}
}
What it does show is how easy it is to use XWPF to create documents.
