title: Launch .war in wildfly with no Datasource
body: <p>I'm getting this ridiculous error:</p>
  
  <p>jboss.naming.context.java.module.helloworld.helloworld.DefaultDataSource is missing [jboss.naming.context.java.jboss.datasources.ExampleDS]</p>
  
  <p>Which I don't get since my war doesn't use persistence. Do I really need to have a datasource to launch a war?</p>
