How to set UsernameToken to a Binding Reference Service with policy enabled

Question

I have a composite Designed in the following fashion:
     *AQ_Adaptor[AQ] ------------> Mediator[MD] -------------> ServiceReference[SR]*
SR is another composite service exposed which has the wss_username_token_over_ssl_service_policy enabled,
In the above process i apply the wss_username_token_over_ssl_client_policy in EM console
but how do i pass the username token credentials, as the process starts with a listener???? , would appreciate any help
Tried creating the Map and Key in the EM cosole and set it as the csf-key for the reference service but that too did not help.
Would also like to share that if I create the policy at design time and set the credentials policy property in the composite.xml for the binding reference,
then it works well.

Answer 1

Did the following to resolve the issue
-> Create a credential Store in EM console
-> Set the key on the policy applied to the Binding Reference.
But now i have one dependency,
I have to make reference to the binding URL on SSL port in my composite to the SR which throws a compile time warning.
