Hello,
I am using Cocoon 2.0.3 with Tomcat 4.0.4. I have activated the Parent
Component Manager to use my own "SimpleLuceneCocoonIndexerImpl" and other
classes.... When Cocoon starts I get an exception:
WARN (2002-10-24) 13:10.15:386 [core.manager] (Unknown-URI)
Unknown-thread/ExcaliburComponentManager: ComponentLocator exception from
parent CM during lookup.

The method in the Component Manager that throw the Exception ->

this.jndiName);
Hashtable environment = new Hashtable();
environment.put(Context.INITIAL_CONTEXT_FACTORY,

//
// Yes, this is cheating, but the Excalibur in-memory naming provider
// is transient. That is, it doesn't store objects persistently and
// is more like a HashMap.
//
// Should be:
// Context initialContext = new InitialContext(environment);
//
Context initialContext = Configurator.initialContext;
Configuration config = (Configuration) initialContext.lookup(this.jndiName);
// We ignore the setRoleManager call, as ExcaliburComponentManager handles
that
// in configure().
this.delegate.setLogger(logger);
this.delegate.contextualize(new DefaultContext());
this.delegate.configure(config);
this.delegate.initialize();
this.logger.debug("Component manager successfully initialized.");
}
Any suggestions??
Thanks
