Apache POI XWPFDocument object serialization

Question

I'm using Apache POI methods to create and fill XWPFDocument object in my project, smth like this

public XWPFDocument test() {
 XWPFDocument doc = new XWPFDocument();
 ...

 return doc;
}

but thre's a problem, for my case XWPFDocument should be serialized. Is there any way to serialize it?

Promoting a comment to an answer...

The way to serialise a XWPFDocument (or in fact any POI UserModel document) is via the write(OutputStream) method

If you need to serialise to a byte array, you'd do something like:

XWPFDocument doc = new XWPFDocument();
...

ByteArrayOutputStream baos = new ByteArrayOutputStream();
doc.write(baos);
return baos.toByteArray();

Assuming you want to serialise into something like a database or persistence framework, just get the OutputStream from that and write into it directly!
