How to invoke ALSB proxy service externaly

Question

Hello,
I.m trying to understand the ALSB and stumble across an issue and hope one of you guys (from BEA) can help out?
I've created the services from the Mortgage services tutorial successfully and now I'm trying to invoke the proxy services externally. By externally I mean as a partner link from within Oracle BPEL. So far this does not work. The error message states a missing protocol in the service URL. I checked this and it is true: the wsdl of the proxy service contains only a relative path (/loan/gateway1), so the protocol and server name and port are missing. Further, I tried to change the URI of the proxy service, but ALSB does only allow a relative URI.
My question is: what am I missing so the proxy service can be invoked externally?
I am on the right solution path to invoke a proxy service instead of a business service, right!?
Thank in advance.
Regards,
Harm Verschuren

I tracked down the problem. The proxy service and the business service it routes to use rpc encoded. The RPC encoded message comes to the proxy service from BPEL which transmits it without modification to the business service. The WLS web service that impements the business service is unable to decode the message persumably because it did not like the way BPEL encoded the message. Below is the message part that BPEL sent: All the xsitype attributes are part of RPC encoding.If you use the alsb test console to pass this message directly to the business service, you will see the decoding error thrown by wls.
