But I have added all the dependencies in relevent pom files. Is it
something to do with the MANIFESTs? But I included all package imports and
exports to the manifests as well, and still the jmx-activator module is not
activated when tuscany is boot strapped.

To access the runtime objects Have created a new object of
ExtensionPointRegistry
ExtensionPointRegistry extensionPoints = new
DefaultExtensionPointRegistry();
Then the Domain's Composites, Components Endpoints are accessed by
DomainRegistryFactoryExtensionPoint
DomainRegistryFactoryExtensionPoint factories =
extensionPoints.getExtensionPoint(DomainRegistryFactoryExtensionPoint.class);
And I have posted the code snippet how I'm accessing these objects
for (DomainRegistryFactory factory :
factories.getDomainRegistryFactories()) {
Collection<DomainRegistry> domainRegistries =
factory.getEndpointRegistries();
for (DomainRegistry domainRegistry : domainRegistries) {
compositeManagement.register(domainRegistry.getDomainComposite());
List<Component> componentList =
domainRegistry.getDomainComposite().getComponents();
for (Component component : componentList) {
componentManagement.register(component);
List<ComponentService> componentServiceList =
component.getServices();
for (ComponentService componentService :
componentServiceList) {
componentServiceManagement.register(componentService);
}
}
Collection<Endpoint> endpointCollection =
domainRegistry.getEndpoints();
for (Endpoint ep : endpointCollection) {
endpointManagement.registerEndpoints(ep);
}
}
}
Is it because of a missing dependency that I'm not getting data to these
objects?
