title: Get JSON elements from a web with Apache Flink
body: <p>After reading several documentation pages of Apache Flink (<a href="https://ci.apache.org/projects/flink/flink-docs-release-0.10/apis/streaming_guide.html#example-program" rel="nofollow">official documentation</a>, <a href="http://dataartisans.github.io/flink-training/" rel="nofollow">dataartisans</a>) as well as the examples provided in the <a href="https://github.com/apache/flink" rel="nofollow">official repository</a>, I keep seeing examples where they use as the data source for streamming a file already downloaded, connecting always to the localhost.</p>
  
  <p>I am trying to use Apache Flink to download JSON files which contain dynamic data. My intention is to try to stablish the url where I can access the JSON file as the input source of Apache Flink, instead of downloading it with another system and processing the downloaded file with Apache Flink.</p>
  
  <p>Is it possible to stablish this net connection with Apache Flink?</p>
