How PI receiver could be sender in other's

Hello All,

As per design changes in one of our interfaces, some of receivers are now into sender for other receivers, so please tell me how to design this flow in PI.

File /File sender adapter ->PI->call JavaMap-->WS(Response payload)-->JDBC/sender or receiver adapter->PI-->Oracle/database(response)->PI->File adapter/receiver-->NFS folder

Here WS response was input for JDBC/Oracle and Oracle response was input for PI.

There is a little confusion in JDBC adapter/ looks ups need to use in this design, and also does it required BPM for make it one scenario?

Thanks for your time and let me know your design inputs.

Thanks,

Gayatri.
