What do you mean by "pull"?

What information do you see for a OneWay?

What information are you expecting?

I'm not sure what exactly you are talking about.  A (png) screen shot would be
useful if you are talking about what you see in jconsole.

I can't answer this until I understand more of what's above it.

I mean to get the monitoring data.As of now I am trying to get the
monitoring data through JMX API.Thats the reason I used the word "pull"
.Sorry for the confusion created.

I see in one pager that monitoring development work has been done for
OneWayFeature and I want to see what data is exposed from a OneWay
webservice.

Examining the OneWayFeature code I see

    /**
     * {@inheritDoc}
     */
    @ManagedAttribute
    public String getID() {
         return ID;
    }


With my understanding of the code  I want to see if I get the ID
value(in this case "http://java.sun.com/xml/ns/jaxws/addressing/oneway"
as defined in the class definition ) in the data exposed using jconsole
.Here goes my question:

Which attribute listed in the attributes section will give me
information about the OneWay feature of the service?Is it the "features"
attribute? Please find screenshot 1.png attached.

> What information are you expecting?

I am expecting some information like this:

id=http://java.sun.com/xml/ns/jaxws/addressing/oneway
enabled=true

See screenshot 4 .

Screenshot 2 is taken when the service is annotated with  @OneWay and 3

,4 are taken when the annotation @MTOM is also used.

P.S : I am still learning and please do point me to my misunderstandings
if any .

Yes, it is "features".

The screen shots definitely show MTOM in the feature list but not anything about
  OneWay.

>>> Is it because OneWayFeature is not a Subclass of

Jitu or Rama will need to answer a question:  What would cause something
regarding OneWay to show up in features?

Thanks,

Yes, it is "features".

I am expecting some information like this:

id=http://java.sun.com/xml/ns/jaxws/addressing/oneway
enabled=true

The screen shots definitely show MTOM in the feature list but not anything about  OneWay.

Is it because OneWayFeature is not a Subclass of javax.xml.ws.WebServiceFeature in JDK 6?

Jitu or Rama will need to answer a question:  What would cause something regarding OneWay to show up in features?

Thanks,

Harold

Hi,
This is a unsupported feature just used for internal working of WSIT.
This feature is a misnomer and is just a hack to pass ReplyTo, FaultTo
etc to workaround an issue in WSIT even though the operation says it is
oneway.
It does not relate to oneway message exchange behavior of JAX-WS.

First, I don't see any reason why this should be exposed in monitoring.
If our intent is to just see all the features that are enabled, we
should expose the name of the feature, which users are more familiar
with than the esoteric ID. I think we should not expose the attributes
of this feature as the semantics are not well defined.

thanks,
Rama Pulavarthi

Ok.I understand.A document/blog describing various WebserviceFeatures
and their usage would be helpful although some of them are described in
various blogs.

Apart from this OneWayFeature class, are there any other classes that
are not supported as of now?

Yes I have to map the id defined in each subclass of WebServiceFeature
to the actual WebserviceFeature being used from the source code.
