I need to dynamically generate word search pdf on the web. Teachers will type in their own words on web site, and I need to generate word search pdf, word search result pdf. My backend code is java. I will use iText to generate pdf. I'm not sure where to start. Please help. I think with hard work, I probably can figure out word search pdf sheet, but how can I generate the word search solution? Which will have lines to circle the words. Is there anything out there I can already use?
