You do not need a WSDL contract to develop a service consumer. You can create a service consumer from an annotated SEI. Along with the SEI you need to know the address at which the endpoint exposing the service is published, the QName of the service element that defines the endpoint exposing the service, and the QName of the port element defining the endpoint on which your consumer makes requests. This information can be specified in the SEI's annotations or provided separately.
To create a consumer without a WSDL contract you must do the following:
Create a Service
object for the service on which
the consumer will invoke operations.
Add a port to the Service
object.
Get a proxy for the service using the Service
object's getPort()
method.
