Use this example when creating a web service that implements the NotificationConsumer portType defined by the Web Services Base Notification specification.
The following example WSDL document describes a web service that implements the NotificationConsumer portType defined by the Web Services Base Notification specification:
<?xml version="1.0" encoding="utf-8"?> <wsdl:definitions xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:wsn-bw="http://docs.oasis-open.org/wsn/bw-2" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="uri:example.wsn/consumer" targetNamespace="uri:example.wsn/consumer"> <wsdl:import namespace="http://docs.oasis-open.org/wsn/bw-2" location="http://docs.oasis-open.org/wsn/bw-2.wsdl" /> <wsdl:binding name="NotificationConsumerBinding" type="wsn-bw:NotificationConsumer"> <wsdlsoap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http" /> <wsdl:operation name="Notify"> <wsdlsoap:operation soapAction="" /> <wsdl:input> <wsdlsoap:body use="literal" /> </wsdl:input> </wsdl:operation> </wsdl:binding> <wsdl:service name="NotificationConsumerService"> <wsdl:port name="NotificationConsumerPort" binding="tns:NotificationConsumerBinding"> <wsdlsoap:address location="http://myserver.mycom.com:9080/Consumer" /> </wsdl:port> </wsdl:service> </wsdl:definitions>
The following example shows a basic implementation of the Service Endpoint Interface (SEI) generated from the preceding WSDL document using the WSDL2Java tool:
public class ConsumerExample implements NotificationConsumer { public void notify(NotificationMessage[] notificationMessage, SOAPElement[] any) throws RemoteException { // Process each NotificationMessage for (int i=0; i<notificationMessage.length; i++) { NotificationMessage message = notificationMessage[i]; // Get the contents of the message SOAPElement messageContent = message.getMessageContents(); // Get the expression indicating which topic the message is associated with TopicExpression topic = message.getTopic(); // Get a reference to the producer (this value is optional and so might be null) EndpointReference producerRef = message.getProducerReference(); // Get a reference to the subscription (this value is optional and so might be null) EndpointReference subscriptionRef = message.getSubscriptionReference(); // User defined processing ... } } }
