New issue 359 by alexonho...@gmail.com: NullPointerException when
converting a sample docx to pdf file
http://code.google.com/p/xdocreport/issues/detail?id=359

What steps will reproduce the problem?
1. Code:
public class Docx2Pdf {

public static void main(String[] args) throws IOException {
long start = System.currentTimeMillis();

InputStream is = new FileInputStream(new
File("/Users/chengliang/docs/unmarshallFromTemplateExample.docx"));
XWPFDocument document = new XWPFDocument(is);
PdfOptions options = PdfOptions.create();
OutputStream out = new FileOutputStream(new
File("/Users/chengliang/out/test.pdf"));
PdfConverter.getInstance().convert(document, out, options);

System.err.println("Generate pdf with " +
(System.currentTimeMillis() - start) + "ms");
}
}
2. I was using
<dependency>
<groupId>org.apache.pdfbox</groupId>
<artifactId>pdfbox</artifactId>
<version>1.8.3</version>
</dependency>

<dependency>
<groupId>fr.opensagres.xdocreport</groupId>

<artifactId>fr.opensagres.xdocreport.converter.docx.xwpf</artifactId>
<version>1.0.3</version>
</dependency>


What is the expected output? What do you see instead?

Your docx seems very strange. It doesn't contains w:sectPr in your
word/document.xml. This sectPr gives the width/height of the page. Without
that I don't know how to retrieve it?

Have you used MS Word to create this word? If yes, which version do you use?

Thanks for taking a look.

I was using Docx4j and the word file I used comes from one example there. I
used my Mac MS word 2011 to save it again and now xdocreport can process it.

Can you please let me know how you debug it? Otherwise please feel free to
close this bug .

It's the first time that I have this case (word/doucment.xml doesn't
contains w:sectPr) and as I have explained you, I don't know which
width/height I must use. I close this issue, but If some people are the
same problem, I will study it more how to fix it. But if you use MS Word
you should not have this problem.

I have noticed too that you use ${colour} in your docx without mergefield.
You will have trouble if you don't use mergefield to merge your docx with
java context. I suggest you to read

Hi I am also facing the same issue (NullPointerException).
There are two ways to create docx file:
1) Generating docx file using apache poi. while trying to convert that
generate docx file to pdf i am getting exception.
2) Create docx file using MS Office, i am not getting any exception and pdf
conversion is successful..

Can you please help me to resolve this issue?

I have no time to support that today, any PR are welcome!

try add "document.createNumbering()" whose variable document is your XWPFDocument before invoke PdfConverter.getInstance().convert().
