   A success message may appear if everything is correctly configured. If not, then recheck the connection parameters and the precise execution of the steps above.
   
  -NOTE: Since WildFly is not yet final, it's absolutely normal it may present some instability during the datasource configuration, requiring you to restart the server one or more times to get things working. Make sure to report every strange behavior in https://community.jboss.org/en/wildfly?view=discussions[WildFly's forum], https://lists.jboss.org/mailman/listinfo/wildfly-dev[mailing list] or even https://issues.jboss.org/browse/WFLY[submit a bug].

   The same datasource can be created using the following command:
   
       [standalone@localhost:9990 /] /subsystem=datasources/data-source=AppDS:add(
           driver-name=mysql,
           user-name=db_user,
           password=secret,
  -        connection-url:jdbc:mysql://localhost:3306/appdb,
  +        connection-url=jdbc:mysql://localhost:3306/appdb,
           min-pool-size=5,
           max-pool-size=15,
           jndi-name=java:/jdbc/AppDS
  
positive.code: 
      #> jboss-cli.sh(.bat) --connect 
  
  It connects to `localhost` and port `9990` by default. The prompt looks like `[standalone@localhost:9990 /]`, indicating it is ready to accept admin commands. Type `quit` when you are done. Command line examples are spreaded througout the text.
