[esb-java-dev] Logging

[Kattubadi Basher Ahamed]

Thanks ,
 But if it Asynchronous call, how to maintain property in message context object, 
Example Asynchronous call: once I receive message from client I will put request message to internal java queue and I will add property in message context for this request message.
When back end service send response after some time , the response flow doesn't know the property of request message which request flow set, so how can I get in response flow which property  was set  in request 

Thanks in advance please reply

Basher

Hi Basher,

I think usage of the message id for this purpose is not the correct approach for this scenario. Assuming that this queue is an internal Java queue which stores the message context object you could use a property with a given name to associate the request and the response, so in the response flow these properties will be copied to the response.

If you are storing these messages as SOAP or XML messages in a JMS queue or any other external queue I propose you to use a custom SOAP header to keep the information about the request / response association. In this particular case you will need to add the value for the response message before reporting to the queue, well same with the request I guess. You could still use a property to correlate the request and the response in the synapse flow.

Thanks,
Ruwan
