Class CMIContext

java.lang.Object
  org.ow2.carol.cmi.jndi.context.CMIContext

All Implemented Interfaces:

javax.naming.Context

@NotThreadSafe
public final class CMIContext
extends java.lang.Object
implements javax.naming.Context

The CMI context intercepts the accesses to JNDI and delegates the management of cluster view at an instance of ClusterViewManager which is a singleton. An instance of CMIContext is relative at a protocol. Instances owned by a server must have a local registry to perform operations such a bind.

                  java.lang.String initialContextFactoryName)
           throws CMINamingException

Constructs a new CMI context from a given environment. Clients must call this constructor.

Parameters:

serverRefs - a set of references on server to perform lookups

protocol - the protocol associated (JRMP, IRMI or IIOP)

initialContextFactoryName - a factory to construct real contexts

Throws:

CMINamingException - if the default LB policy for access to JNDI cannot be retrieved
