Recently I am working on commercial project which requires to generate a PDF based on some dynamic HTML content, now I have implemented that with a java library called WKHTMLTOPDF (http://wkhtmltopdf.org/).
This library is a command line tool which user browser webkit as rendering engine, since I am new to java development, I am not sure whether there is any security or performance issue when using this library.
If this is not a good solution, is javascript plugin an alternative?
Sorry for my english!:)
