Publishing REST Web Services

A REST Web service publishes a set of views and associations and makes them available to external applications that cannot use the JDBC or ODBC interfaces.

REST Web services provide similar features and work pretty much in the same way as the RESTful Web service described in the section RESTful Web Service (i.e. the service at http://acme:9090/denodo-restfulws). However, there are a few features that the REST web services have and the RESTful web service do not:

  • You can provide access to a limited set of views, instead of to all the views.

  • You can rename the names of the fields of the published views.

  • Set mandatory input fields.

  • Support for RSS.

To create a REST Web service, right-click on the view you want to publish, in the Server Explorer and click REST Web service on the menu New > Data service or click REST Web service in the menu File > New > Data service.

The “Create REST Web service” dialog has the following tabs:

  • Resources: lists the views and associations published by the Web service. You can add more by dragging a view. See section Resources Tab.

  • Settings: manages the configuration of the REST Web service. See section Settings Tab (REST).

  • Advanced: manages the parameters of the connection between the Web service and the Virtual DataPort Server and other advanced settings. See section Advanced Tab (REST).

  • Metadata: select the target folder of the Web service and provide a description for it.

After configuring everything, click Save to create the Web service. The Tool will display the “Web service container status” table that lists the existing Web services. Then, you can deploy the Web service in the embedded Web container or generate the war file and deploy it in an external Web container (see section Web Service Container Status Table).
