WKHtmlToPdf wkhtmltopdf = new WKHtmlToPdf();
wkhtmltopdf.convert("<html><body>Hello Native World!</body></html>", "./test.pdf");
In order to compile the library you first need to install wkhtmltopdf from http://wkhtmltopdf.org/.
After that just run make:
make

and store results in target/ directory.
If you want to run a quick test run make run. After it's done you should see file named test.pdf.
