| DefaultServiceController | | abstract public class DefaultServiceController implements ServiceController(Code) | | Default implementation of a Service Controller. It
gets from a
ServiceReplyCatcherConfig object the following
configuration parameters:
- defaultServiceTimeOut: The default time out for a service.
- containerURL The URL that identifies the container, to
avoid problems in certain NAT configurations.
The main objective of this class is to provide the reply of a service
by following these steps:
- Asks the abstract method getPersonalizedReplyRequest for an
object of class
PersonalizedReplyRequest suitable for calling
this service. The composition of this PersonalizedReplyRequest
object will be specific for the service being called, and will be
constructed by a subclass of this one.
- Calls the method getRealURL, which builds the URL which
will be used to call the service by examining the
PersonalizedReplyRequest object.
- Calls the
ServiceReplyCatcher .getReply method, passing as
parameters the URL to call and the timeout for the request, which
will be the one configured for this service (if it has been
specified) or the default time out (if it has not).
