JSON Web Service Server entity

The Web Service Server entity contains the main logic to publish services. It listens for incoming requests and executes the relevant service operation.

For a entity, the Type property states "WebServiceServerJSON". The XML representation of a JSON Web Service Server entity is a .4wsjprg file.

When a Web Service Server entity is implemented from the diagram, a .4gl source file is generated which contains the MAIN function for the application. This .4gl file is also used to combine the other generated .4gl files into a Genero application.

Any changes to the BA diagram are included in the subsequent re-generating of the program code.

The generated code can be customized.

Properties

The 'public' property on the RecordField node is used by SOAP and JSON web services.
