PDFreactor is a formatting processor to convert HTML and XML to PDF. It uses Cascading Style Sheets (CSS) to define page layout and styles. It allows you to dynamically generate PDF documents such as invoices, delivery notes, shipping documents, or print versions of Web content on-the-fly. Vector graphics (SVG), barcodes, MathML, XSLT, and CMYK colors are supported. All common J2EE application servers are supported. Complete .NET, PHP, Perl, Python, and Ruby APIs are included. Direct integration into automatic build processes using Apache Ant is also possible.
i-net Doqua is an Eclipse plug-in that helps documentation writers and developers to keep track of inconsistencies between style guides and the actual documentation. The system integrates into the Eclipse IDE and introduces a new perspective and several views. Since i-net Doqua uses standard JUnit testcases to check the documentation, you can trigger checks using Hudson or similar Ant based systems.
