title: Spring MVC pdf generation
body: <p>I have a java web application based on Spring MVC. 
  The task is to generate a pdf file. As all knows the spring engine has its own built-in iText library so the generating of pdf file is really simple. First of all we need to do is to overload AbstractView and create some PdfView. And the seconf thing is to use that view in controller. But in my application I am also have to be able to store generated pdf files on local drive or give my users some link to download that file. So the view in that case is not suitable for me. </p>
  
  <p>I want to create some universal pdf generator that creates a pdf file and returns the bytes array. So I can use that array for file storing (on hard drive) or printing it directly in browser. And the question is  - are there any way to use such engine (that returns only the bytes array) in PdfVIew solution? I am asking because overloaded buildPdfDocument method (in PdfView) already have PdfWriter and Document parameters.
  Thank you</p>
