Hazelcast serialization between cluster members

Question

I have a configuration class which store in hz IMap
This configuration class is part of 1-st instance member
P.S members are two different applications.

public class AConfiguration implements Serializable {
private String name;
private ApplicationSystem appSystem; //enum
private Map<String, ConfigParams> config params;
//getters setters;
}

This configuration is pushed to IMap from 1-st cluster Member as Object

My goal is to see this configuration in another module

How to serialize that object in 2-nd member instance?
If a invoke

IMap<Key, Object> d = hazelcastInstance.getMap("CACHE");

I got com.hazelcast.nio.serialization.hazelcastserializationexception

Answer 1

Make sure that inner objects of AConfiguration are also serializable. Also, it is recommended to put serialVersionUID as stated in official hazelcast docs.
