RE: why I cant find this service

[Mu Mike]

Thank you, Aaron( is that your first name?)

The chart works at least for fortress(sorry, I checked those items only for 
fortress), and I have another question(I have mailed this question but no 
one answered ,since you answered my every question, I guess it is better 
for me to go to you asking for help), the questions is:

How should I understand the idea of hierarchial containers? my situation is 
the below.

I m wrting a 'block' which uses only one Container to hold all the 
configrations read from roles and xconf file, I did like this: 

  final FortressConfig config = new FortressConfig(); 

  config.setContextDirectory(""); 
  config.setWorkDirectory(""); 
  config.setContainerConfiguration("system.xconf" ); 
  config.setRoleManagerConfiguration("report.roles"); 
  config.setLoggerManagerConfiguration("logkit.xconf"); 

  ContainerManager cm = new 
            DefaultContainerManager(config.getContext()); 
     ContainerUtil.initialize( cm ); 

  DefaultContainer container = (DefaultContainer) cm.getContainer(); 
  ServiceManager manager = container.getServiceManager(); 

Using that manager, I can look up every service I need in my block. The 
question is , my block is supposed to be used in an uppper level block 
which has some configurations useful to my block.I guess it somehow has its 
own ServiceManager, so how can I use this ServiceManager(or what else) to 
get those configurations? I think this must have something to do with the 
hierarchical containers idea, Can anyone tell me how to achive this goal?

In Fortress, if you want the ServiceSelector, you must add "Selector" to 
the
name of the role.

Full semantics are now on:

I'm fairly sure I got Merlin and Fortress down right.  Not sure about
Phoenix.  Let me know if that chart doesn't make sense.

That's another one of those things I used to know but will now have to
lookup.  Berin might know off the top of his head.  I think it's the
ThreadSafe handler, but I'll still need to check.
