Example: Pausing a WS-Notification subscription

This example code describes a JAX-RPC client acting in the subscriber role, pausing a subscription for a consumer application.

Example

This example is based on using the Java™ API for XML-based remote procedure calls (JAX-RPC) APIs with code generated by using the WSDL2Java tool (run against the Notification Broker WSDL generated as a result of creating your WS-Notification service point) and WebSphere® Application Server APIs and SPIs.

This JAX-RPC example can interact successfully with Version 6.1 or Version 7.0 WS-Notification service points. However if you want to use WS-Notification with policy sets, for example to enable composition with WS-ReliableMessaging, then your WS-Notification applications must be encoded to use the Java API for XML-based Web Services (JAX-WS) programming model and must interact with Version 7.0 WS-Notification service points. If you are new to programming JAX-WS client applications, see the following topics:
// Look up the JAX-RPC service. The JNDI name is specific to your web services client implementation.
// The PauseSubscription operation belongs to the SubscriptionManager service
InitialContext context = new InitialContext();
javax.xml.rpc.Service service = (javax.xml.rpc.Service) context.lookup("java:comp/env/services/SubscriptionManager");

// Get a stub for the port on which you want to invoke operations
SubscriptionManager stub = (SubscriptionManager) service.getPort(SubscriptionManager.class);

// Associate the request with the subscription you want to pause. The subscriptionEPR is the
// EndpointReference returned by the invocation of the Subscribe operation
((Stub) stub)._setProperty(WSAConstants.WSADDRESSING_DESTINATION_EPR, subscriptionEPR);

// Create any optional information
SOAPElement[] optionalInformation =  new SOAPElement[] {};

// Invoke the PauseSubscription operation by calling the associated method on the stub
SOAPElement[] additionalReturnedInformation = stub.pauseSubscription(optionalInformation);
