Transport can not be determined from uri REPLACE_WITH_ACTUAL_URL

you deployed a project and it went successfully now when you are testing this project you are getting following error

Unable to invoke endpoint URI "REPLACE_WITH_ACTUAL_URL" successfully due to: java.lang.IllegalArgumentException: Transport can not be determined from uri REPLACE_WITH_ACTUAL_URL

The reason for this error is that the binding for the composite does not contain the actual end point URL.

I opened the service and found that in the composite reference for one of external web service

in the binding there was a location of physical wsdl file.

This happens when you migrate a code from SOA 10g where there is no concept of MDS.
