a) I am getting the following error while trying to run my application.
java.lang.IllegalStateException: Cannot respond to resolve request as the
appliance appliance:/tutorial/Hello3 is in a non-commissioned state.
at
org.apache.avalon.activation.impl.DefaultAppliance.resolve(DefaultAppliance.
java:162)
at
org.apache.avalon.activation.impl.ApplianceInvocationHandler.getInstance(App
lianceInvocationHandler.java:172)
at
org.apache.avalon.activation.impl.ApplianceInvocationHandler.invoke(Applianc
eInvocationHandler.java:110)
at $Proxy9.execute(Unknown Source)
Is there related to the ordering in which the components should be started.
If yes, then what is the best way to declare the components in block.xml.
b) When there are two components providing the same service, then is it
possible to dynamically load a particular service implementation by
providing the dependency key.
ie.. in the following example
<component name="gloria" class="tutorial.IdentifiableComponent"/>
<component name="nancy" class="tutorial.IdentifiableComponent"/>
<component name="hello" class="tutorial.HelloComponent">
<dependencies>
<dependency key="primary" source="gloria"/>
<dependency key="secondary" source="nancy"/>
</dependencies>
</component>
Is it possible to load the service based on the key "primary". (I want to
dynamically load even after declarinng the dependencies in the xml because
then i can manually commission the models)
ComponentModel model = (ComponentModel)
m_containmentModel.getModel(reference);
model.commission();
Object obj = model.resolve();
