Forward from WS Proxy to MPG

Currently, I am validating a SOAP request using ws proxy. How can I forward the same request to a MPG object from ws proxy ?
Do I have to write a stylesheet, any example or any pointers please.
Thanks

This sounds like a bad idea. If schema validation is the only value that you get from WS-Proxy, why not pull a VALIDATE step into the MPGW policy and do it all in one step (with a dynamically determined schema of course)?
Don't be fooled into service chaining because it is convenient. Every chained service incurs additional overhead in payload serialization, parsing and XML validation. It is possible to undo all the inherent performance optimization of the SOA Appliance platform by bouncing the same payload off of a bunch of services.
The most successful SOA Appliance customers have a maximum of 2 chained services (only when necessary), and a minimum of rules to drive those services, but each action is driven dynamically with multi-step variables.

Thanks for your input Corey. Your point is well taken and I completely understand what you say.
But I wanted to see service chaining in action and did not get to understand how to forward a request from ws proxy to a mpgw. Appreciate if you can throw some light on it.
Thanks

In the "Proxy settings" tab for the Web Services Proxy you have the field "Backend URL". Enter the MPG address there and thats all. Remember that for the proxy "Type" you need to have "static backend" to be able to enter the backend url.

I believe you mean the IP and Port combination of the MPGW front side handler in the 'Backend URL' field. Correct me if I am wrong.
Thank you.
