title: Document-Rendering in Java
body: <p>I want to render MSWord, PDF, HTML, etc to an image (e.g. TIFF) from server-side Java. </p>
  
  <p>Most available products are shareware printer drivers, and so not suited to a commercial server app: I'd like the library which is robust, well-supported, performant, and concurrent.</p>
  
  <p>Any suggestions for open-source or commercial libraries?</p>
