I am developing a web application to get user input and query data from mysql DB using jsp+servlet. After that I need to fill in the data to a pdf template (retrieve from tomcat8/webapps/project/pdf/ folder etc) using itext and show the pdf on user browser. And finally allow user save the filled pdf to mysql DB. Would you please suggest which kinds of program code (itext + jsp or itext + servlet) is better to suit my above case? Thank.
