   ### Application Configuration for the Datasource
   
  
positive.code:         connection-url=jdbc:mysql://localhost:3306/appdb,
          min-pool-size=5,
          max-pool-size=15,
          jndi-name=java:/jdbc/AppDS
      )
  
  The resulting part made by the console/command in the configuration file are:
  
negative.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. Before using them, please remove all line breaks and identation spaces, making them a continous text string. For example:
  
  Instead of doing exactly this:
  
      [standalone@localhost:9990 /] /subsystem=datasources/jdbc-driver=mysql:add(
          driver-name=mysql,
          driver-module-name=com.mysql,
          driver-class-name=com.mysql.jdbc.Driver
      )
  
  You should do this:
  	
      [standalone@localhost:9990 /] /subsystem=datasources/jdbc-driver=mysql:add(driver-name=mysql,driver-module-name=com.mysql,driver-class-name=com.mysql.jdbc.Driver)
  	
  We decided to change the presentation to improve readability.
