Using cache on a Singleton bean
-------------------------------

                 Key: ISPN-1338
                 URL: https://issues.jboss.org/browse/ISPN-1338
             Project: Infinispan
          Issue Type: Enhancement
          Components: CDI integration
    Affects Versions: 5.0.0.FINAL, 5.0.0.CR8, 5.1.0.FINAL
         Environment: infinispan-cdi 5.1.0-SNAPSHOT, jboss AS 7 (all libs packaged within ear)
            Reporter: Vinicius Carvalho
            Assignee: Manik Surtani
            Priority: Optional


I'm trying to get the CDI examples to work on an app. so I've created this config:

@Produces
	@ApplicationScoped
	@OverrideDefault
	public EmbeddedCacheManager getCacheManager() {
		GlobalConfiguration gc = GlobalConfiguration.getClusteredDefault();
		gc.fluent().transport().clusterName("shared-cache-cluster").addProperty("configurationFile", "jgroups-tcp.xml");
		Configuration c = new Configuration().fluent().clustering().mode(CacheMode.REPL_ASYNC).build();
		return new DefaultCacheManager(gc,c);
	}

BTW, trying to use configuration and @Infinispan with this I get an error when CacheManager tries to get the cache, I've discussed it at http://community.jboss.org/thread/171005?tstart=0

Well, my scenario has 2 apps one on each node. So in one node I put a value in the distributed cache, and I expect to receive an event on the other node.

My problem is that the events for a cache are only hooked when the cache is first accessed (According to CacheManager:getAdvancedCache).

So, in my second ear, if there's no "warm-up" of the cache, the events do not get hooked and I don't get any notification.

So I tried to use a Singleton:

@Singleton
@Startup
public class CacheWarmupBean(){

@Inject Cache<String,String> cache;

@PostConstruct
void warm(){
cache.getCacheName();
}
}

Problem is that the bean gets started before the extension, and no target is found for the cache.

I wonder, is it possible to either warmup the cache on a different way or hook the events?
