Warning: I have posted this on StackOverflow as well about 4 days ago but it has gotten no responses so I thought I would try my luck on this forum. I will update it with any responses I may get here. My question:
I am trying to add a digital signature to an xlsx file... Can't seem to find any resources for this (other than adding signatures to literal/regular xml files). Is this possible with docx4j? I see it includes jaxb-xmldsig but there are no samples that I could find. Perhaps someone could point me in the right direction?
