creating a word document using coldfusion

Hi, if you want is it possible to use Java Apache POI but the best way is to choose PDF alternative.

Here a sample guide in Java https://www.baeldung.com/java-microsoft-word-with-apache-poi

I would suggest you create not a Word document, but an HTML document instead. Create it within a CFM page, of course, perhaps using an HTML form or table. Use CSS to style the HTML to your needs.

I am assuming that you wish to generate a separate contract for each user. You could, for each user, use a query to fetch the details of the user from the database and populate the fields in the HTML. You could then generate a PDF from the HTML using cfdocument or cfhtmltopdf.

In an application I worked on years ago, the signature of each user had been recorded beforehand and stored in the database as a small image. The image had the same dimensions for each and every user.  The image would be obtained from the database, and the <img> tag was used to place it on the precise signature-location in an HTML document.

Nowadays it is customary to digitally documents (even after they've been manually signed). You can use cfpdf to digitally sign PDFs.
