Counting pages in a Word document

Question

I'm trying to count pages from a word document with java.

This is my actual code, i'm using the Apache POI libraries

String path1 = "E:/iugkh";
File f = new File(path1);
File[] files = f.listFiles();
int pagesCount = 0;
for (int i = 0; i < files.length; i++) {
    POIFSFileSystem fis = new POIFSFileSystem(new FileInputStream(files[i]));
    HWPFDocument wdDoc = new HWPFDocument(fis);
    int pagesNo = wdDoc.getSummaryInformation().getPageCount();
    pagesCount += pagesNo;
    System.out.println(files[i].getName()+":\t"+pagesNo);
}

The output is:

ten.doc:    1
twelve.doc: 1
nine.doc:   1
one.doc:    1
eight.doc:  1
4teen.doc:  1
5teen.doc:  1
six.doc:    1
seven.doc:  1

And this is not what i expected, as the first three documents' page length is 4 and the other are from 1 to 5 pages long.

What am i missing?

Do i have to use another library to count the pages correctly?

Thanks in advance

Sounds like Word hasn't bothered to update the statistics in the files (depressingly common). If you open the file in word, view the stats then save, does that fix it? — Gagravarr
is this working now? tested it with poi-3.9 version it did worked for me. Thanks — teckysols
have u resolved issue? can u tell me how you gets pages count? — Muneem Habib
@MuneemHabib No, I did not solve the issue. It actually works with document metadata, if Word doesn't update it, you won't be able to get page count. — BackSlash
@BackSlash i have offest value i want get page number where this offset lies any idea? — Muneem Habib

This may help you. It counts the number of form feeds (sometimes used to separate pages), but I'm not sure if it's gonna work for all documents (I guess it does not).

WordExtractor extractor = new WordExtractor(document);
String[] paragraphs = extractor.getParagraphText();

int pageCount = 1;
for (int i = 0; i < paragraphs.length; ++i) {
    if (paragraphs[i].indexOf("\f") >= 0) {
        ++pageCount;
    }
}

System.out.println(pageCount);
