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.

  1. 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.
  2. 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.
  3. 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.
  4. You generate the service description artifacts, which means interfaces, business objects, and other XML structures are created in your module.
