I would suggest that we confine the usage of beans to config reader only(even if they can be accessed publicly), cause we need to copy the property values from bean to the corresponding real instance (e.x DirectoryServiceBean -> DirectoryService) and this is better to it in the reader, so we don't need this copying anywhere else to setup a service (one particular area I see is in embedded mode, currently in embedded server we are not able to
use external config, but with the new single file LDIF based config it is now possible and setting up a server gets easier too from a user's pov)

I'm not sure this is a good idea :
- if the configBean does the Bean -> real object conversion, then the configBean will have to be aware of the real object. In any case, there is a tight relation between config and entities, and it has to be expressed in either place.
- As configBean can be used to store partial results (it contains AdsBaseBeans), you have no way to know which kind of objects you'll get from it : ot can stores AdirectoryService beans (and more than one), Servers, etc.
- if the service init needs to read the configBean and search for the exact Bean it has to use, then that mean the service has to know where in the config hierarchy will be stored the Bean. Not very convenient, IMO
- also the reader reads, it does not instantiate. In Studio, we don't care instantiating anything, so there is no reason to have this part done in the reader. I created a ConfigCreator for this purpose, btw

Agree with you, the main thing I want to see is to have a single plave where this bean -> real service object conversion/mapping/creation 
happens.
So instead of we changing the startLdap() method to startLdap( directoryServiceBean.getLdapServerBean(), directoryService );

we need a config handler/creator to do this and give us the DirectoryService which we can use directly to start. Am I making sense?
ATM, the ConfigCreator class is doing the conversion. 

We can do : startLdap( directoryServiceBean, directoryService )

that would be probably better.

If we go any further, another approach would be to nae all the beans, and use PicoContainer :

startLdap( container, directoryService )

where inside the startLdap we would do :

  LdapServerBean ldapServerBean (LdapServerBean)container.get( "ldapServer" );

but this is not where we want to go, I guess...

Description

I have modified the ApacheDsService start method this way :

    public void start( InstanceLayout instanceLayout ) throws Exception
    {
        File partitionsDir = instanceLayout.getPartitionsDirectory();
        
        if ( !partitionsDir.exists() )
        {
            LOG.info( "partition directory doesn't exist, creating {}", partitionsDir.getAbsolutePath() );
            partitionsDir.mkdirs();
        }

        LOG.info( "using partition dir {}", partitionsDir.getAbsolutePath() );
        
        initSchemaLdifPartition( instanceLayout );
        initConfigPartition( instanceLayout );

        // Read the configuration
        cpReader = new ConfigPartitionReader( configPartition, partitionsDir );
        
        ConfigBean configBean = cpReader.readConfig( "ou=config" );
        
        DirectoryServiceBean directoryServiceBean = configBean.getDirectoryServiceBean( "default" );
        
        // Initialize the DirectoryService now
        DirectoryService directoryService = initDirectoryService( instanceLayout, directoryServiceBean );

        // start the LDAP server
        startLdap( directoryServiceBean.getLdapServerBean(), directoryService );

        // start the NTP server
        startNtp( directoryServiceBean.getNtpServerBean(), directoryService );

        // Initialize the DNS server (Not ready yet)
        // initDns( configBean );

        // Initialize the DHCP server (Not ready yet)
        // initDhcp( configBean );

        // start the ChangePwd server (Not ready yet)
        startChangePwd( directoryServiceBean.getChangePasswordServerBean(), directoryService );

        // start the Kerberos server
        startKerberos( directoryServiceBean.getKdcServerBean(), directoryService );

        // start the jetty http server
        startHttpServer( directoryServiceBean.getHttpServerBean(), directoryService );
    }
