Class DataServiceWebServiceImpl

java.lang.Object
  com.metamatrix.soap.service.DataServiceWebServiceImpl

public class DataServiceWebServiceImpl
extends java.lang.Object

This class is the main implementation of the MetaMatrix Data Service feature. It is the 'router' that marshalls all Data Service web service requests to the MetaMatrix Server and returns the results in the return web service response. This class represents a 'virtual' web service because it has no set web service interface. An instance of this class will serve all Data Services that are deployed to all VDB's of the MetaMatrix Server.
