HazelcastClientCachingProvider class not found exception when requesting hazelcast jcache provider

Question

I'm having a strange warning when I try to use Hazelcast-based implementation of JCache (i.e. JSR 107) as follows (original sample code):

// Explicitly retrieve the Hazelcast backed javax.cache.spi.CachingProvider
CachingProvider cachingProvider = Caching.getCachingProvider(name);
// Retrieve the javax.cache.CacheManager
CacheManager cacheManager = cachingProvider.getCacheManager("com.hazelcast.cache.impl.HazelcastCachingProvider");

Here is the logged message:

oct. 30, 2014 5:17:59 PM com.hazelcast.cache.impl.HazelcastCachingProvider
WARNING: Could not load client CachingProvider! Fallback to server one... java.lang.ClassNotFoundException: com.hazelcast.client.cache.impl.HazelcastClientCachingProvider

Why it si trying to load HazelcastClientCachingProvider will I asked for com.hazelcast.cache.impl.HazelcastCachingProvider. Am I using the wrong JCache provider?

Answer 1

HazelcastCachingProvider is just a delegate to automatically choose either client based or server bases CachingProvider.

For recent 3.4 SNAPSHOTS HazelcastCachingProvider also was moved to com.hazelcast.cache.HazelcastCachingProvider. For the new documentation please see the just drafted documentation version for 3.4: https://github.com/hazelcast/hazelcast/blob/master/hazelcast-documentation/src/JCache.md

You'll see it got waaaaaaay longer :)
