how to convert HTML to .docx using docx4j?

I read some articles about the conversion of html to .docx and I found out that docx4j gives pretty decent results. I wonder if anyone could provide me the following info:

1. Needed jars and versions.
2. Sample code for conversion from html to .docx.

Sorry I couldn't post anything I tried because I haven't tried anything on this task yet, although I use Apache POI to convert the bytes[] I get from datatabse to html to output in a rich text editor on a jsf application. Please enlighten me, I'm lost in stress and confusion...!
