hi stephen,
just to clarify, i have the feeling that the creation of the DefaultKernel does all
the commisioning automatically:
Factory factory = builder.getFactory();
Map criteria = factory.createDefaultCriteria();
criteria.put("merlin.deployment", new String[] { "bin"});
criteria.put("merlin.debug", "true");
criteria.put("merlin.info", "true");
DefaultKernel kernel = (DefaultKernel) factory.create(criteria); // <===== SEEMS
TO LOAD AND START THE BLOCK
produces the output:

the following code lines do not work:
ContainmentModel containmentModel = kernel.getModel();
ReferenceDescriptor reference = new
ReferenceDescriptor(Identifiable.class.getName());
ComponentModel componentModel = (ComponentModel)
containmentModel.getModel(reference); // <===== EXCEPTION
componentModel.commission();
Identifiable ident = (Identifiable) componentModel.resolve();
System.out.println("====> " + ident.getIdentity());
the exception is:
org.apache.avalon.composition.model.ProviderNotFoundException: Unable to locate a
service provider for the reference: [

what is a service provider? am i looking i a wrong model? hmm...
