FlyingSaucer/XHTMLRenderer (https://github.com/flyingsaucerproject/flyingsaucer) does a good job of HTML > PDF conversion however it does not work by magic: there are a few steps involved.

Assuming you wanted to export an existing JSP via some Link or Button:

• PDF export Button calls a some Controller or Servlet passing all params necessary to regenerate the JSP (i.e. as it was originally rendered).

• This Action or Servlet has to invoke the JSP (ensuring any required
  model attributes are set) and write the Response to a String (rather than writing to the standard response).

• Pass this String to XHTMLRenderer to generate the PDF.

• Stream the btye [] returned by HTMLRenderer to the client.

I have added a complete end-to-end example here using a simple Servlet. However the principles will be the same with any framework so you should be able to adapt as required.
