Use this task to write the code for a JAX-RPC client acting in the subscriber role, pausing a subscription for a consumer application, based on the example code extract provided.
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.
The following example code describes a JAX-RPC client acting in the subscriber role, pausing a subscription for a consumer application:
// 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);
