I am interested in this aspects too.
>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.

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 -- anees On Tue, Nov 30, 2010 at 9:51 AM, anees k A <[email protected] <mailto:[email protected]>> wrote: Damitha, Were you able to locate anything from the logs?

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? -- anees On Fri, Nov 26, 2010 at 6:02 AM, Samisa Abeysinghe <[email protected] <mailto:[email protected]> <mailto:[email protected] <mailto:[email protected]>>> wrote: Do you have your data sync working?
