            +--org.apache.axis.AxisEngine

All Implemented Interfaces:
  Handler, java.io.Serializable

Direct Known Subclasses:
  AxisClient, AxisServer

public abstract class AxisEngine
extends BasicHandler

An `AxisEngine` is the base class for AxisClient and AxisServer. Handles common functionality like dealing with the handler/service registries and loading properties.
