Use

The JNDI Registry Service has two ways of caching:

·        Objects are put in the cache as object instances – used from applications. Elements are added in this cache only through a lookup operation performed by an application running on this server.

·        Objects are put in the cache as byte arrays – used from all clients. Elements are added in this cache through a lookup operation performed by any client.

CacheCommunicatorImpl is registered as a message listener and performs the communication among the JNDI Registry Services in the different servers in the cluster. It is used to notify the cluster about the changes in the cache, which concern the global objects. If an unbind, rebind, or rename operation is performed over a global object, the object will be removed from the cache on the current server. A message with the object name will be sent to all other servers to inform them about the invalid global object.
