Hello,

I am planning to implement my application with the following layers:

Client -> REST(Resteasy) -> Business Logic Layer -> Data access layer -> DB

I am using Wildfly 10.1.0.Final

I am just confused on how the Business layer should be implemented in order to be injected, if so, into the REST service layer....

At the moment I have this:

@Path("/hello")
@Produces({ "application/json" })
@Consumes({ "application/json" })
public class HelloWorld {
  public HelloWorld() {} 

  @GET
  @Path("/world")
  public Message getHello(){
    return new Message("Hello World!!"); 
  }

Message class is not an Entity at the moment, can I just use my entities as the return type?

I am planning to implement my business layer using CDI Managed Beans, so for example if I have a business class MessageService , should I inject it inside my REST class HelloWorld ?

Is there some documentation, article or tutorial that can guide?

Thanks
