Class EnactorXMLServer

java.lang.Object
  context.arch.enactor.server.EnactorXMLServer

All Implemented Interfaces:

java.lang.Runnable

public class EnactorXMLServer

extends java.lang.Object

implements java.lang.Runnable

An XML server that tunnels all enactor events through sockets to clients, using XML to translate DataObjects to a language-independent serialized format. As client connections are created, each client becomes an EnactorListener to the Enactor passed into the server constructor. In this sense a server represents a single enactor. Different enactors use different servers and so have different addresses and ports. The specific protocol used for XML is compatible with the Macromedia Flash XMLSocket. Also, the EnactorXMLServer responds with HTML information about the Enactor when it receives HTTP GET requests. So, the one server on the single port acts as both an XML server and as a simple HTTP server.
