Use Case :
This example demonstrates how to get the URI of the backend service from a repository and how to set it dynamically to our partnerLink (dynamicPartnerLink).

Implementation steps :

1. Create a dvm file
2. Create a BPEL component
3. Add the endPointURI variable and assign the uri
4. Set the endpointURI property in the invoke activity
