Hazelcast Blueprint Camel Karaf - apache-camel

Question

I am new to hazelcast and trying to implement hazelcast using blueprint and karaf.
I am stuck at the first step in creating the instance although it working for me using just spring.
When I run the bundle on karaf, it times out.
Please ignore typo error in bean class name except the hazelcast ones as I changed the name for security purpose.
Here is my bluprint

Below is my referred maploader class. For now I am return null in all the methods for testing purpose.
public class ResetVehicleInitial implements MapLoader<String, String>{
private static final String DIRECT_LOAD_RESET_VEHICLE_INITIAL="direct:loadResetVehicleInitial";
#EndpointInject(uri=DIRECT_LOAD_RESET_VEHICLE_INITIAL)
private ProducerTemplate loadResetVehicleInitial;
#Override
public String load(String arg0) {
// TODO Auto-generated method stub
return null;
}
#Override
public Map<String, String> loadAll(Collection<String> vehicleintial) {
// TODO Auto-generated method stub
System.out.println("hello");
List loadValues = loadResetVehicleInitial.requestBody(DIRECT_LOAD_RESET_VEHICLE_INITIAL, vehicleintial, List.class);
System.out.println(loadValues);
return null;
}
#Override
public Iterable<String> loadAllKeys() {
// TODO Auto-generated method stub
return null;
}
}
After suggestion from Jereme, I modified my xml according to java class:

You can't mix "spring namespaces" in a blueprint configuration, at least with the current version of aries (which, apparently, you are using)
You should create an HazelcastInstance in a java class, without the help of the 'hz' namespace.
Moreover :
Gemini blueprint, another implementation of blueprint, support the
use of spring namespace in a blueprint file
Spring DM, (which is now obsolete but still work with spring <= 3..), can either support the use of spring namespace, in a spring configuration in META-INF/spring
I have seen an experimental support of spring namespace in aries blueprint, but i have never tryied it personnally, it's a work-in-progress (i haven't seen any "official communication" about this feature)
