Savan/C implements the Web services Eventing specification

>From an architectural point of view we have two paradigms
1. We have the provider / consumer paradigm and
2. We have the publisher / subscriber paradigm
In the provider / consumer paradigm the consumer polls on
a regular basis for information provided by the provider
In a publisher / subscriber paradigm, the subscriber
subscribes once with the publisher and defines the
information it is interested in and
the publisher informs the subscriber when the information
becomes available or it delivers the information straight
to the subscriber up on availability
Can you provide the implementations used to implement one
or both paradigms.
Savan/C is basically a pub/sub implementation

Hi,
I am still stuck at this. Can anyone please help me.
Could reproduce your problem. Will look into this asap
Also please help me understand the following point.
"This is not part of Savan implementation. Subscriber
is supposed
to "know" his own data sink."
So how does the subscriber know some data is published?
Will it
keep on polling the sink at periodic interval? (Please
excuse my
lack of understanding.)
You need to handle the communication between your listner
service and your client program

Damitha,
Were you able to locate anything from the logs? I can
see the
service getting listed using web-browser. Also if I invoke
"listener" (sink) separately, it is working. Any idea
why this is

1. No data is published.
Log files are attached with this mail. Please note
that the
logs attached are only for two commands from
"subscriber" app
- Subscribe and Generate weather event.
2. "This is not part of Savan implementation.

Samisa,
Using the browser I can see the data sync
listed. Also
I used the sample application hello that
comes with
Axis2/C to check the functionality of the
"listener"
data sync. It is working fine.
Can you grab the message published to the data sink
through tcpmon?. If the data is not published at
all,
please send me the savan log file
To verify my understanding :
1. Subscriber subscribes to Data source for
an event
2. Data source, when an event, as subscribed
by the
subscriber, is generated, publishes the data
to the
data sink
Yes when an event generated the data source
publish it to
the corresponding subscribers, data sink.
who in turn informs the subscriber.
This is not part of Savan implementation.
Subscriber is
supposed to "know" his own data sink.
Damitha
Is this understanding correct? In this tutorial,
http://wso2.org/library/3149 this is not clearly
mentioned. Can you please help me?

Hi,
I am trying to understand Savan/C
implementation. While trying
out the sample
subscriber-weather-listener
example, I am
seeing the below error :
[error] publisher.c(225) Publishing

This happens when I am trying to
issue the
command "5 Generate
weather event" from subscriber app.
Any idea
why this is
happening ? I am running axis2c
server and
installed Savan/C
to axis2c.
