I also think that it is doing a lot of things that are done very cleanly outside of #vertx by #gRPC and if I were going to focus on this as an area or work I'd rather put my time into making that sort of integration seamless. The gRPC plugin for vertx is ripe with possibilities here, but it is more focused on the #JAXRS-style use case instead of the internal one.

But I am more interested in other aspects of this problem right now and on getting a test bed up and running.

#Apache #CXF and other #JAXRS providers are able to generate #Java #Proxy clients from annotated interfaces

I am now gladly reading that upcoming #Spring 6 is getting a similar feature for #REST services https://docs.spring.io/spring-framework/docs/6.0.x/reference/html/integration.html#rest-http-interface
#OpenSource rocks either way!

So, did you ever wonder how to test your @JakartaEE@twitter.com #JAXRS endpoint correctly without starting a full blown container? Here's how using Apache CXF or Eclipse Jersey:
