Problem in scenario JDBC - > XI -> File

Hi,

In my scenario, data is fetched from database and passed on to external file. In my design i have put source structure which is exactly the same as database structure and mapped it to target structure. Message interfaces for both the source and target message types are asynchronous outbound and asynchronous inbound respectively. in the communication channel for sender service, i have taken JDBC adapter as sender adapter and for reciever, file adapter.

After activating the change list, i can see that JDBC adapter is able to connect to the database but not doing any message processing. similarly in adapter ramework monitoring, File adapter is showing "Up and running. no mesage processing until now".

Can somebody guide me in finding the possible location of error?

Do i need to specify the table name and action in the message mapping as in the case with outbound JDBC adapter? is the mapping adapter dependent in this case?

Best Regards,

Nitin Aggarwal.
