Re: GWT + Open API

Thank you, Rogelio, for your input.

I like the idea of generating the data model from the OpenAPI
specification, because I will not have to write some boring
error-prone code. I also like the optimization of the GWT compiler.

The swagger-codegen can output Jaxrs Cxf Client, which has the API
interface defined with JAX-RS annotations. So it seems that even the
interfaces could be auto-generated. You only have to modify them so
that they extend RestService, required by RestyGWT.

Have you tried auto-generating the API interfaces with Jaxrs Cxf Client?

In your previous message you wrote that you auto-generate a GWT
module. What do you specifically mean by a module here? Do you use
some publicly-available tools, or do you have something home-grown?
