I have two node Hazelcast (3.4.1) cluster running. I have configured it to use native memory. (Basically trying to use high density memory store). Have written a client code to connect to those cluster to perform write operation.
I trying to configure Jcache with Hazelcast in order to use cache store. Jcache provider type: client. Also I want use declarative configuration Below is my client code & configuration XML.
public class Test {
public static void main(String[] args) {
try {
System.setProperty("hazelcast.config",
"classpath:conf/hazelcast.xml");
System.setProperty("hazelcast.jcache.provider.type", "client");
CachingProvider cachingProvider = Caching.getCachingProvider();
CacheManager cacheManager = cachingProvider.getCacheManager();
ICache<String, Object> cache = cacheManager.getCache("Classroom",String.class, Object.class).unwrap(ICache.class);
CacheConfig cacheConfig = cache.getConfiguration(CacheConfig.class);
System.out.println("key type: " + cacheConfig.getKeyType());
System.out.println("value type: " + cacheConfig.getValueType());
cache.put("1", "value1");
System.out.println("-->" + cache.get("1"));
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

I have even tried based on the examples provided for jcache. It didn't work out. Not sure where I am going wrong. Also I am not sure jcache is configured. As mentioned in documentation, have all the dependent jars.
Usecase: To have Hazelcast cluster with native cache (high density memory store) enabled. Hazelcast Java client (jcache configured) runs on another node should connect to this cluster and perform read/write operation in to the cache.
