Now that I\'ve figured out how to use JAXB generate JSON I can request/respond with it on my server and I\'d like to figure out how I can generate useful documentation for human
Also try enunciate, it parses the javadoc and JAX-RS annotations of your service classes to generate documentation:
http://enunciate.codehaus.org/
Here is some example documentation generated by enunciate:
https://repository.sonatype.org/nexus-restlet1x-plugin/default/docs/index.html
There is a maven plugin that works well.It also generates client libraries in various languages as well as sample xml for xml based services. It now supports swagger documentation as well.
