@Path("hello")

Customization

An initial set of value can be preloaded and merged by exposing a Map<String,String> like e.g.:

import java.util.HashMap;
import java.util.Map;
import javax.enterprise.inject.Produces;

public class InitialConfiguration {

    @Produces
    public Map<String, String> get() {
        Map<String, String> cache = new HashMap<>();
        cache.put("com.airhacks.jc2.boundary.HelloResource.greeting", "hey duke");
        return cache;
    }
}

Administration

headlands exposes JCache API as a REST service and also uses Hazelcast as an SPI. Deploy headlands and use the cache with the name configuration to maintain the contents.
