SOAP to IDoc scenario without BPM

Hi,

I have 2 scenario's

1) IDoc-SOAP - -response -- IDoc scenario -- (have found some links  to do it without BPM)

2) SOAP -- RFC request -- RFC response -- e-mail (no links found)

please help us to achive this scenario without BPM.

Your help is highly appreciated.

thanks,

Praveen
