Asynchronous to Synchronous Scenerio

Hi All:

Can any one let me know how to go for Asyn to Syn scenrio using BPM. Here is the requirement :

JMS(Asyn) ---to ---HTTP(Sync)

I am sending the message to the target system and and getting response from it. Now if any Error is coming, so by cheking there type (like if its is type ='E') I have to call the Mail adapter.

I beleive it is possible with BPM. But what steps, Abstract interfaces will be there?

I have source Message, Target and Targes_resp Message.

Now according to that what are the Abstract Interfaces??

Thanks
