RE: why I cant find this service

[Mu Mike]

Thank you first of all.

yeah, your configuration files works,but then

roles files written for ECM should be different in format from new files 
written for fortress.

By having this form of role description , I guess all the implementation 
classes of a service which share the same role name should have 
'root-level' configurations instead of childern level configurations of the 
configuration of the Service they implmented like that in ECM role files. 
So a roles file and a xonf file maybe like this:

 <role name="Runner">
   <component shorthand="DefaultRunner"
              class="DefaultRunner"
              
handler="org.apache.avalon.fortress.impl.handler.ThreadSafeComponentHandler"

              />

   <component shorthand="AnotherRunner"
              class="AnotherRunner"
              
handler="org.apache.avalon.fortress.impl.handler.ThreadSafeComponentHandler"

              />
 </role>             

 <my-system>
  <DefaultRunner id="default"/>
  <AnotherRunner id="Another"/>
 </my-system>
Is this right?

And, when I call ServiceManager.lookup("Runner") method, what it will 
return me?, in ECM, for this situation, I would get an 
ExcaliburComponentSelector instance because the configuration would be like 
this:

 <role
   name="Runner"
   shorthand="Runner"
   
default-class="org.apache.avalon.excalibur.component.ExcaliburComponentSelector">

   <hint shorthand="DefaultRunner" class="DefaultRunner"/>
   <hint shorthand="AnotherRunner" class="AnotherRunner"/>
 </role>
and the .xconf file

 <my-system>
  <Runner>
    <DefaultRunner/>
    <AnotherRunner/>
  </Runner>
 </my-system>
then use that selector, I can select an expected implementation component 
by passing the selector the value of the hints. So can fortress return me a 
ServiceSelector with the configuration files I have at the beginging of 
this text, and then I can select using the shorthands ?

And, what is the default handler class if I havent an explicit handler 
class?

Thanks
Mike.

I don't think anyone has answered you yet, so here's my shot.  I think 
your
problems are in the configuration files (which have changed a little).

Change this to:

<?xml version="1.0"?>
<role-list logger="system.roles">
  <role name="Runner">
    <component shorthand="runner"
               class="DefaultRunner"
               handler=
      
"org.apache.avalon.fortress.impl.handler.ThreadSafeComponentHandler"
     />
  </role>
</role-list>

> This is my system.xconf file
>
> <my-system>
>   <runner/>
> </my-system>
This should be changes slightly to:

<?xml version="1.0"?>
<my-system>
   <runner id="default"/>
</my-system>
I think all components need an 'id' attribute now.  It serves as an alias 
to
the role name.

All the rest of the code works.  Let me know if this solves your problems.
