title: Why Oracle Apex send Web Service request from Oracle Database and not from Apex Listener?
body: <p>I have configured Application Express 4.2.2.00.11, using Oracle Apex Listener 2.0.3, connected to an apex instance on a different Server. It is playing well except when i try to consume a web  service (Amazon S3, Google Geocode, etc.), i noticed that need Oracle Database instance to have internet connection. It is surprising because i was expected only to allow Listener container server connect to internet. </p>
  
  <p>So i want know if is there any way to consume Web Services in Oracle Apex without expose database server to internet (connecting Apex Listener only to internet).</p>
