Dynamic JAXB: Flickr Example
This example will demonstrate how to use MOXy's Dynamic JAXB features to work with public JSON and XML feeds, without having to create concrete Java classes.
Getting JSON from Reddit
Reddit provides a public JSON feed using the following URL format:
http://www.reddit.com/r/science/top/.json?sort=top&t=day&limit=5
This will return us the following JSON. For this example, we are only interested in the title and url fields of data/children/data.
{
"kind":"Listing",
"data":{
"modhash":"qdohhwkxss9091dc13eed91db333b619420a787aa2a39b3982",

...Getting XML from Flickr
Flickr provides a public XML feed using the following URL format:
http://api.flickr.com/services/feeds/photos_public.gne?tags=science
This will return us the following XML. For this example, we are only interested in the title and url fields of data/children/data.
<?xml version="1.0" encoding="UTF-8"?>
<feed xmlns="http://www.w3.org/2005/Atom" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:flickr="urn:flickr:user" xmlns:media="http://search.yahoo.com/mrss/">
