Pattern of accessing external services with adapters
Use the external service wizard to access external services follows a similar pattern regardless of the adapter you are using.
You would follow the steps described below with the external service wizard to get the service metadata artifacts from a system you are searching and generate a service.
- Connect to a host system. A host system could be a server name or a URL address. Connecting to a system may involve security details, depending on the security setup in your organization.
- Once the external service wizard connects to the system, it searches the metadata repository for the artifacts available to import and presents them as a list.
- You make selections from the list. Depending on the adapter, you may be able to configure each selection, and configure the entire selection. Your selections create a query.
- You generate the service description artifacts, which means interfaces, business objects, and other XML structures are created in your module.
