In WSFL you don't bind individual ports, but complete services. The locator
element allows you to specify how to select a service to bind to a service
provider. Note that service providers are typed by service provider types,
which are nothing but sets of portTypes. Hence, when you bind the service
provider to a service you are also binding each portType in the service
provider type to a port in the selected service. Note that there is an
exception to this model, namely, activities that are dynamically bound
based on received data using mobility locators.

Hope this helps,

Subject:  WSFL question


I have a question regarding the WSFL specification, I hope this is
the right place to ask. It is unclear to me how to specify a particular
binding/port to use for an activity.

Static locators have a service attribute, but as far as I understand,
this field references a "service", which may be composed of several
ports, possibly for the same port type.

On the activity side, only abstract operations and port types are

So, is there some other place to say which port I want to use for a
service ? Otherwhise, how can the workflow engine choose between the
different ports that may be offered by a service for the same port
type ?

Best regards,
