title: What does Grails create-service do exactly?
body: <p>I am developing a Grails application (with Grails 1.3.7). In service layer, I did not use the command 'create-service' to create my service but do it manually.  </p>
  
  <p>As the result, my service was not auto initialize in controllers and other services, and it did not handle transaction.</p>
  
  <p>But I do not know where is the differences from create service by command with by manual? Because I do not see any configuration file which figure out this? (I mean in traditional Spring, we always have some configuration files which specify all beans in applications, but in   Grails is not).  </p>
  
  <p>I want to fix this issue and commit to SVN server my fix, but I do not want to delete the old service and commit the new one which is created by Grails command. So could you please help me:<br>
  1. explain what is the differences from create service by command with by manual?<br>
  2. how to change the the service created by manual to service created by command without replacing the old one?<br>
  Thank you so much!</p>
