Hello! https://github.com/thiagohp/tapestry-rest-example contains what I'd consider the simplest example possible of using the Tapestry REST support using a JSON-mapped entity class, User, both for receiving (i.e. request body) and returning data. No usage of JSONObject or JSONArray in the REST endpoint page classes. POJO <-> JSON conversions provided by Jackson Databind.
The classes you should take a look at are UserRest (the implementation of a few REST endpoints), AppModule (specially the coercion and component event result processor contribution) and UserComponentEventResultProcessor (which allows event handler methods to return an User instance and have it automatically mapped to JSON and returned). Don't forget to take a look at app.properties as well, since it's heavily used by the OpenAPI generator. You can easily run the project by running the RunWithJetty class under src/test/resources. It'll run the webapp under http://localhost:8080. The generated OpenAPI JSON description file is available at http://localhost:8080/openapi.json. The project includes tapestry-openapi-viewer, which embeds Swagger UI ( https://swagger.io/tools/swagger-ui/) and is available at http://localhost:8080/opeanapiviewer. As always, feedback of all kinds is welcome, and so are questions. :) Cheers! -- Thiago
