Hi Everyone!
We all have viewed, used or sent PDF files and it is surely one of the most informative and common document formats on the internet.
In this discussion, I would like to share an implementation of generating PDFs from the HTML of a webpage(s) programmatically and easily.
We will make use of two Java libraries: Flying Saucer and iText, along with that to JSOUP – another open-source Java library has been used, for modifying the HTML dynamically.
You can get more information on the Flying Saucer API here.
Here is a brief overview of the implementation :
- An interface/component with a button, on click of which an AJAX call (using GET method) will be triggered.
- Path of the page to be converted to PDF will be selected by the author in a dialog which will be sent as a parameter to the servlet.
- In response we are generating a PDF which opens in a new tab, the user can save it with any name he/she wishes.
- Requests have been implemented to get all the HTML from the page and the CSS that is being applied on the page.
- iTextRenderer object is used to set the layout and generate the PDF.
- To render images MediaReplacedElementfactory is implemented which replaces the image element with iText image element which can be rendered by Flying Saucer API.
- Utility class using Jsoup has been used to handle all the HTML manipulations i.e removal of certain tags like button, header, and footer of the page.
- Special CSS has been applied for certain cases to make sure the PDF layout is looking good.
In this blog post, I am going to explain how to implement these steps along with the code required.
