title: Get the hostname from a DataSource class
body: <p>Is there a way to get the hostname from the DataSource class in java? I mean, I have a DataSource object (DS), which is annotated to get the Jboss datasource. Anyway, I want to get the hostname used in that DS.</p>
  
  <p>Debugging, i can see it this way: I get the Connection from DS, then I get the DataSourceMetaData and inside of that the is something called Protocol Connection which have the hostname, but I don't know how to get it.</p>
  
  <p>Anyone here knows how? or another way to get the hostname? 
  Thanks in advance. Kind regards, RDAM</p>
