jrunx.rmi
Class Invocation

java.lang.Object
  |
  +--jrunx.rmi.Invocation

All Implemented Interfaces:

ClusterConstants, java.io.Externalizable, java.io.Serializable

Direct Known Subclasses:

EJBContainerInvocation, EJBInvocation, RemoteSQLInvocation

public class Invocation

extends java.lang.Object

implements ClusterConstants, java.io.Externalizable

This class encapsulates a remote method invocation to a JRun system. It is the parent to EJB Invocation Contexts and is used directly for remote JNDI and remote service invocations.
