Class ContextPropagatingRemoteInvocation

java.lang.Object

org.springframework.remoting.support.RemoteInvocation

org.springframework.security.remoting.rmi.ContextPropagatingRemoteInvocation

All Implemented Interfaces:

Serializable

public class ContextPropagatingRemoteInvocation
extends RemoteInvocation

The actual RemoteInvocation that is passed from the client to the server.

The principal and credentials information will be extracted from the current security context and passed to the server as part of the invocation object.

To avoid potential serialization-based attacks, this implementation interprets the values as Strings and creates a UsernamePasswordAuthenticationToken on the server side to hold them. If a different token type is required you can override the createAuthenticationRequest method.
