Hi Gero It's all handled with the call to producerClient.subscribe(consumer, null, null); http://ws.apache.org/muse/docs/2.2.0/javadoc/org/apache/muse/ws/notifica tion/impl/SimpleNotificationProducer.html
Where parameter 2 is for your filter (topic), see http://ws.apache.org/muse/docs/2.2.0/javadoc/org/apache/muse/ws/notifica tion/impl/TopicFilter.html And the parameter 3 is for your policies. At least that's my understanding, I'm sure Dan has a better clarification. Based on my understanding I would say you need to put the topic of choice in the 2 parameter position in your .subscribe call /Lenni -----Original Message----- From: Gero Vermaas [mailto:[EMAIL PROTECTED] Sent: 21 March 2007 11:40 To: [email protected] Subject: How to subscribe to topic Hi, This may be a very basic question, but I have not been able to find a answer myself yet... I've got the following code: Topic topic = ... URI producerEndpointURI = new URI(producerEndpointURL); EndpointReference epr = new EndpointReference(producerEndpointURI); String webAppRoot = "/ossj-tck-wsn-consumer/services"; String contextPath = webAppRoot + "/consumer"; URI address = getLocalAddress(contextPath, consumerPort); EndpointReference consumer = new EndpointReference(address); // null filter == send all messages to consumer producerClient = new NotificationProducerClient(epr); producerClient.setTrace(true); wsnPropagator.subscribe(wsnTopicQName, this); producerClient.subscribe(consumer, null, null); The question I now have it how do I till the producer that the client wants to subscribe to a specific Topic. As a background, I'm building the client side and the guys building the server side that sends out the notification expect something like <wsnt:TopicExpression Dialect="http://docs.oasis-open.org/wsn/2004/06/TopicExpression/Simple";> System/JSR264/ApplicationType/OrderManagement/Application/0-11;0-0;Refer enceImplementation/Comp/XVTEventTopic </wsnt:TopicExpression> as part of the subscribe request. I can't find a way to tell the producer the topicexpression. Is there an example that illustrates this?
