Serializer is not able to find my business classes and throws HazelcastSerializationException/ClassNotFoundException

In Memory Format - 'BINARY' works fine for storing objects in distibuted map. 

hz:map name="mymap"  max-idle-seconds="0"  in-memory-format="BINARY"
backup-count="0" max-size="0" eviction-percentage="30" read-backup-data="true"
eviction- policy="NONE" />

Moment I change in-memory-format to "OBJECT". An error is thrown as: 

com.hazelcast.nio.serialization.HazelcastSerializationException:
    java.lang.ClassNotFoundException:com.Customer

I am running a single node to start a hazelcast instance (hz:hazelcast id="instance")

I have another clinet configured (hz:client id="client") to put "Customer" in map as:

IMap<String, Customer> objectMap = hazelcast.getMap("mymap");  
Customer customer = new Customer("gupta", 33);  
objectMap.put(key , customer);

with OBJECT format the above exception is thrown.

To resove this problem I have to add "Customer" in classpath for node manager. This means node manager has to be aware of all the objects that can be added in map(s) at build phase.
