title: Netflix Archaius Dynamic Configuration
body: <p>I am integrating Hystrix in to my existing project and I want to read the configuration values from an xml file instead of feeding the configuration properties using Configuration Manager. When the values are updated in the xml file I want Hystrix configuration to be updated at runtime.</p>
  
  <p>This is the guide I am following: 
  <a href="https://github.com/Netflix/archaius/wiki/Users-Guide" rel="nofollow">https://github.com/Netflix/archaius/wiki/Users-Guide</a></p>
  
  <p>I understand so far that I can use PolledConfigurationSource and the following code:</p>
  
  <pre><code>PolledConfigurationSource source = ...
  AbstractPollingScheduler scheduler = ...
  DynamicConfiguration configuration = new DynamicConfiguration(source, scheduler);
  ConfigurationManager.install(configuration);
  </code></pre>
  
  <p>How do I point PolledConfigurationSource to an xml file to read the properties after a fixed time interval?</p>
