The sample is just a sample that for the sake of the sample continues to
produce messages at a given interval. In short it's a proof of concept that
the messages can be sent and received.
Now if we want to do something a bit more advanced to for example to have a
central NotificationProducer that all the other WSRF compliant services can
call, this might be a way:
package org.extended.test;

{

}
}
Please note the code is not complete as it's sampled from a work in
progress, though it does contain a working NotificationProducer that allows
for other WSRF services to use it.
I didn't add the needed WSDL-file as I assumed you knew how to generate
those and declare any needed public available functions (in this case
runtimeEventOperation ).

Emne: Send NotificationEvent from additional Axis2 WS
Hello,
i have the following situation. A J2me client shall be able to notify a
NotificationProducerWS with certain events.
The NotificationProducer then publishes the event to all subscribed
listeners.
In the WSN Consumer/Producer sample, there is only a producer publishing
events every 10secs to its subscribers, no matter whether anything has
happened or not.
But I want a second (non-emuse) WS sending an event (incl. some data as for
instance a float value) to the producing notification WS. The producer then
pushes the notification message to the listeners.The
subscription/publication is no problem.
I was considering adding a method in the WSN-Producer implementation
(MyCapabilityImpl) that hands over the data and sets a flag for publication.
But how may i do this? and how may i access the Muse WS from outside and
invoke a method in it?
any help is much appreciated (urgent)
