Service Invocation

Services represent the interaction with internal and external applications, such as a database, Java applications or an ERP system. A service may contain several interfaces and each interface may contain multiple operations. Each operation has a schema in the service that defines the operation inputs and outputs. A service interaction represents an activity that invokes a service operation of the following type:

You design an activity that invokes a service operation using a business process with the <<Invoke>> stereotype. This implies that you already have imported services from the WorkSpace environment.

You also need to define the Execute operation implementation type and make sure it is implemented by an operation in a service provider defined in the same model.

• Designing a One-Way Service Invocation
  You design an activity that invokes a One-Way service operation using an <<Invoke>> business process implemented by a One Way operation and with an Invoke Operation action type.
• Designing a Request/Reply Service Invocation
  You design an activity that invokes a Request/Reply service operation using an <<Invoke>> business process implemented by a Request-Response operation and with an Invoke operation action type.
