Instead of using .read() to intermediately save it to memory and then read it to json, allow json to load it directly from the file: wjdata = json.load(urllib2.urlopen('url'))

One can use Apache @Model annotation to create Java model classes representing structure of JSON files and use them to access various elements in the JSON tree. Unlike other solutions this one works completely without reflection and is thus suitable for environments where reflection is impossible or comes with significant overhead.
