    copied!<p>I need a way to bind POJO objects to an external entity, that could be XML, YAML, structured text or anything easy to write and maintain in order to create Mock data for unit testing and TDD. Below are some libraries I tried, but the main problems with them were that I am stuck (for at least more 3 months) to Java 1.4. I'd like any insights on what I could use instead, with as low overhead and upfront setup (like using Schemas or DTDs, for instance) as possible and without complex XML. Here are the libraries I really like (but that apparently doesn't work with 1.4 or doesn't support constructors - you gotta have setters):</p> <p><b>RE-JAXB (or Really Easy Java XML Bindings)</b></p> <p><a href="http://jvalentino.blogspot.com/2008/07/in-response-to-easiest-java-xml-binding.html" rel="nofollow noreferrer"><a href="http://jvalentino.blogspot.com/2008/07/in-response-to-easiest-java-xml-binding.html" rel="nofollow noreferrer">http://jvalentino.blogspot.com/2008/07/in-response-to-easiest-java-xml-binding.html</a></a> <a href="http://sourceforge.net/projects/rejaxb/" rel="nofollow noreferrer"> <a href="http://sourceforge.net/projects/rejaxb/" rel="nofollow noreferrer">http://sourceforge.net/projects/rejaxb/</a></a></p> <p>Seamlessy binds this:</p> <pre><code>&lt;item&gt; &lt;title&gt;Astronauts' Dirty Laundry&lt;/title&gt; &lt;link&gt;http://liftoff.msfc.nasa.gov/news/2003/news-laundry.asp&lt;/link&gt; &lt;description&gt;Compared to earlier spacecraft, the International Space Station has many luxuries, but laundry facilities are not one of them.
