Hello.
I'm having a bit of trouble using the FortressServiceSelector. Let me put it
in the context of the current Fortress Swing example:
Suppose we have two translator components: translator1 and transator2 listed in
the SwingContainer.xconf file. For simplicity they're exactly the same except
for the 'id' attribute. Nothing else in the xconf file is changed.
Additionally, the .roles file is not touched either.
If I add a line or two in the SwingContainer.java class to check what class is
now returned from
m_serviceManager.lookup( ...Translator.ROLE ),
I get this:
DEBUG 2003-02-04 11:14:08.777 [fortress ] (): Object =
org.apache.avalon.fortress.impl.lookup.FortressServiceSelector
Now, I thought I had to do something like
m_serviceManager.lookup( ...Translator.ROLE + "Selector")
to get the ServiceSelector. On top of that, if I do use the ROLE + "Selector"
method, then I get an error regardless of whether I add a "TranslatorSelector"
entry in the SwingContainer.role file:
org.apache.avalon.fortress.InitializationException: Cannot set up impl. Startup
lifecycle failure
at
org.apache.avalon.fortress.impl.DefaultContainerManager.createContain
er(DefaultContainerManager.java:219)
....
Caused by: org.apache.avalon.framework.service.ServiceException: Unable to

(Key='org.apache.avalon.fortress.examples.components.TranslatorSelector'
)
at
org.apache.avalon.framework.service.DefaultServiceManager.lookup(Defa
ultServiceManager.java:117)
....
I'm not sure if I'm just misunderstanding how to use the ServiceSelector or if
it has to do with the difference between ECM and Fortress, or what. Anyone
have any insight?
Thanks,
jaaron
