Interface Summary

Interface	Description
Device	Device.
EventDelegate
InvokeDelegate	Instances of this interface can be used within an OperationStub to implement the actual business logic of a service's operation.
LocalDevice	Interface of local devices.
LocalService	Service.
OperationDescription	Common Interface of operations and event sources.
Service	Interface of service classes representing "DPWS Hosted Services"

Class Summary

Class	Description
AppSequenceManager	Manages the application sequence of device.
BindingContainer	This class represents a combination of the three needed communication informations to communicate with other endpoints.
DefaultClientSubscription	Subscription class, manages a client-side subscription.
DefaultDevice	Implementation of a local device.
DefaultEventSource	Events are the source of server-side notifications to which interested clients may subscribe.
DefaultProxyFactory
DefaultService	Default implementation of a service.
DefaultSubscriptionManager
DeviceCommons	Class represents the common part of a proxy/local device also known as Hosting Service .
EventSourceStub
Fault	Faults are the web-services correspondents to exceptions from the Java world.
Operation	An operation is an abstraction of executable code.
OperationCommons	This class is the common base for both Operations and DefaultEventSources within the JMEDS framework.
OperationStub	Instances of this class are used during dynamic creation of a service via the method DefaultService.define(org.ws4d.java.types.URI, CredentialInfo) .
ProxyDevice	Proxy class of a (remote) device
ProxyFactory	This factory allows to create proxies for devices and services.
ProxyService	Proxy class of a service.
ServiceCommons	Class represents the common part of a proxy/local service.
ServiceCommons.PortType
ServiceReferenceFactory
ServiceSubscription	Instances of this class hold essential information about an event subscription as seen from the server-side.

Exception Summary

Exception	Description
InvocationException	Exceptions of this class are thrown to indicate the occurrence of a user-defined fault during the invocation of a operation or the dispatching of a DefaultEventSource.

Package org.ws4d.java.service Description

Defines a default (local) device and service according to WSD-Discovery specifications, and provides a way to detach an operation's executable code from its metadata.

DefaultDevice constructs a local device (extends DeviceCommons and implements LocalDevice)implementing the functionality of a Target Service as described in the WSDD-Discovery specification. A default device is capable of handling the following types of messages: Probe message, Resolve message, Get message. A default device is then capable of sending the following messages: Probe Matches message, Resolve Matches message, Hello message, Bye message, and Get Response message. A number of services can be added to the device (which must possess at least one communication binding, and be explicitly started for it to function).

DefaultService constructs a local service (extends ServiceCommons and implements LocalService). This class is a template class and does not define any operations. To implementing a working service, the class must be extended and operations created and added to the constructor.

Two operations can have different names but refer to the same code via the OperationStub and InvokeDelegate classes,both classes providing a way to detach the operation's executable code (invoke method) from its metadata.
