Hello Jason,
I am new to docx4j and I was trying to play with this and found something I was doing is not working.
I have a word template(attched:projecttemplate_input.docx) and I hand placed 'place holders' for replacing with dynamic values from database. In my java code, I am reading this template input file and loading WordprocessingMLPackage then I am substituting the place holders with dynamic data from backend. So far so good, replacing works great ...
