getResource().getEnvironment().getAddressingContext() null
Hi,
facing a problem. Did not find any clue in the distribution list. So I post
it.,...
I'm extending the wsn-producer (sample) and would like to anayse the content
of the Filter value set by the Client
when it sends its SubscribeRequest
MyCapabilityImpl extends AbstractWsResourceCapability. So I've tried a
getResource().getEnvironment().getAddressingContext() in my code and get a
null pointer, where getResource().getEnvironment() is not null. I'm
wondering:
- Is it normal as it seems to be the right way to get the messageHeader
values from the received message
- What is the good way to get this filter value set in the Subscriberequest
?
Thanks for your support
Cheers

Posted by vpl <vp...@gmail.com>.
Thanks for your precise answer.
In your proposal I note that I could perhaps do the read somewhere else than
in the initializeComplete() ?
If their is a more natural way to read the filterTopic I can do it... I'm
just in lack of some code sample which could help me in this progress.
I can also overwrite the SimpleSubscriptionManager but again the lack of
code sample is blocking me. Can I do that starting from the wsn-producer ?
Do you have a code sample I could re-use to do that ?
Thanks for your help

Re: getResource().getEnvironment().getAddressingContext() null
Posted by Daniel Jemiolo <da...@us.ibm.com>.
I'm a little confused - it sounds like you are trying to read the values in
order to respond to a subscription (subscribe request), but you are doing
the read in initializeCompleted(). It seems like you would really want to
do this by extending the SubscriptionManager capability
(org.apache.muse.ws.notification.impl.SimpleSubscriptionManager),
overriding initializeCompleted() and use the value of the subscription's
topic to figure out what steps to take next (SubscriptionManager.getFilter
() will return a TopicFilter if you're subscribing to topics). This is
different than trying to add a capability to the producer resource (which
creates the subscriptions).

Re: getResource().getEnvironment().getAddressingContext() null
Posted by vpl <vp...@gmail.com>.
Thanks for your answer. I appreciate. Here is the objective we have:
We want a client to be able to subscribe to different Topics.
We have for example
- subscribe to Group Notification (each time a group of user is modified)
- subscribe to contentRoom (each time a contentRoom is updated).
On the server side, we have several ContentRoom and Group which are
identified by Id (anf java listener via hashtable)
So we would like the Client to subscribe for example
group=groupId1 or
ContentRoom=contentRoomId2
On the server side we need the code to parse correctly the topic value,
such as it (the server) extracts the groupId or ContentRoomId and then drill
down into the low level API (SIP etc..) to start the appropriate listener
for these Ids...
this is the reason why I try to extract the content of the Topic set by the
Client.
I appreciate your responsive support.
Thanks for your help

Re: getResource().getEnvironment().getAddressingContext() null
Posted by Daniel Jemiolo <da...@us.ibm.com>.
I see what the problem is. Resource initialization is done before any
request processing, so the WS-A headers have not been parsed and included
in the context yet. The steps that are happening are:
1. Request sent to server..
2. Server sees request is for Muse app, starts the app.
3. Muse code runs its initialization routine, loading all resources and
calling initialize*() methods.
4. Request is parsed - headers go to context, body is deserialized into
objects.
5. Proper method invoked on resource.
As you can see, #4 would have to happen before #3 in order for you to use
the WS-A context in initializeCompleted(). What are you trying to do? Maybe
we can offer suggestions on how to get there outside of initializeCompleted
().

Re: getResource().getEnvironment().getAddressingContext() null
Posted by vpl <vp...@gmail.com>.
Thanks for your help
No this is not the case.
The place where I call this
getResource().getEnvironment().getAddressingContext() is in the
initializeCompleted()
I call the super.initializeCompleted() before trying to retrieve the
getAddressingContext().
this is the wsn-producer code from which I try to retrieve the
SubscribeRequest message Content.
Am I on the right way ?
Thanks for your help
Th code is the following:
public class MyCapabilityImpl extends AbstractWsResourceCapability
implements MyCapability
{
private static final QName[] _PROPERTIES = new QName[] {
new QName(NAMESPACE_URI, "MessageInterval", PREFIX),
new QName(NAMESPACE_URI, "ServerName", PREFIX)
};
private static final QName _TOPIC_NAME = new QName(NAMESPACE_URI,
"MyTopic", PREFIX);
private static final QName _TOPIC_VPL = new QName(NAMESPACE_URI,
"/*/*/muws1:ManagementEvent", PREFIX);
public QName[] getPropertyNames()
{
return _PROPERTIES;
}
private int _MessageInterval = 10;
private String _ServerName = "16.16.235.174";
public int getMessageInterval()
{
return _MessageInterval;
}
public void setMessageInterval(int param0)
{
_MessageInterval = param0;
}
public String getServerName()
{
return _ServerName;
}
public void setServerName(String param0)
{
_ServerName = param0;
}
public void initializeCompleted()
throws SoapFault
{
super.initializeCompleted();
//
// access resource's WSN capability and create a new topic
//
final NotificationProducer wsn =
(NotificationProducer)getResource().getCapability(WsnConstants.PRODUCER_URI);
wsn.addTopic(_TOPIC_NAME);
if (getResource().getEnvironment().getAddressingContext() == null)
getLog().info("Vpl --
getResource().getEnvironment().getAddressingContext() null");
else
getLog().info("Vpl -- getResource()getEnvironment().getAddressingContext()
not null");
}
}

Re: getResource().getEnvironment().getAddressingContext() null
Posted by Daniel Jemiolo <da...@us.ibm.com>.
A common cause of that is if you override the capability class' initialize
() method but don't call super.initialize(). Is this the case?
