Hi Daniel
The SubscriptionManager itself is included in the WS-specs with Muse,
you just need to add the links in your resource.wsdl (the
muse-template.wsdl on the Muse website should already have all the
needed WSDL code needed).
Now to access the Notification Producer capability within your code a
bit of manual work (see below) has to be done (it's not added in by the
wsdl2java), the example below is for a WSDM resource, more work will be
needed for a WSRF resource as some things are provided by the Muse
framework behind the scenes for a WSDM resource.
To keep the email short and viewable I'll refrain from including the
wsdl for the example below.
Sincerely
Lenni
*** in the MyCapability.java of the resource you wish to have the WSN
producer ***
/**
* External capabilities are instantiated and can be used
*/
public void initializeCompleted() throws SoapFault {
super.initializeCompleted();
runtimeNotification =
(NotificationProducer)getResource().getCapability(WsnConstants.PRODUCER_
URI);
// add list of Topics if needed
runtimeNotification.addTopic(_TOPIC_NAME);
}
// the function called to send a notification, you can add any
parameters //you wish, and it can be private so only functions within
you MyCapability.jav can access it or public to allow others to use it
public Element runtimeEventOperation(){
factory = new SimpleWefFactory();
event = factory.createEvent();
Component reporter = factory.createComponent();
ComponentAddress reporterAddress =
factory.createComponentAddress(getResource().getEndpointReference().toXM
L());
reporter.setAddress(reporterAddress);
reporter.setName(WefConstants.REPORTER_COMP_QNAME);
Component source = factory.createComponent();
ComponentAddress sourceAddress =
factory.createComponentAddress(getResource().getEndpointReference().toXM
L());
source.setAddress(sourceAddress);
source.setName(WefConstants.SOURCE_COMP_QNAME);
Situation situation = factory.createSituation();
situation.setCategoryType(WefConstants.AVAILABILITY_SITUATION_QNAME);
situation.setPriority(Situation.HIGH_PRIORITY);
situation.setSeverity(Situation.UNKNOWN_SEVERITY);
situation.setMessage("Something important has happened in the
"+getServerName()+"!");
event.setReporter(reporter);
event.setSource(source);
event.setSituation(situation);
try{
getLog().info("Sending message to
consumers...");
runtimeNotification.publish(_TOPIC_NAME,
toPublish);
}catch (Throwable error){
error.printStackTrace();
}
return toPublish;
}

Subject: Adding Notification Producer Capabilities to existing
webservice
Hi all,
we have already running a muse 2.2.0 webservice and want to add
notification producer capabilities to it. I somewhat copied & pasted my
existing wsdl into the wsn-producer sample WsResource.wsdl. After some
try
and error (NPE and "only one service allowed") I am now able to generate
my artifacts with
$MUSE_HOME/bin/wsdl2java.sh -j2ee mini -overwrite -wsdl foobar.wsdl
but the generated artifacts don't contain any notification specific
declarations. MyCapability still only extends AbstractCapability, but if
I
generate the artifacts of wsn-producer sample MyCapability extends
AbstractWsResourceCapability.
In addition I'm a bit confused about the WsResource.rmd and
SubscriptionManager.wsdl files, where do they come from and do I have to
edit them?
Any help appreciated,
TIA,
Daniel
