Hi Adam , I have two questions:

1- Do you recommand using only JSF (primefaces) in the whole frontend enterprise application because it really make the developement quick and easy or you like to mix it with some javascript like React / angular or even html5
2- Can we rely on Restful webservices to communicate between the modules of an application with large data exchange.

Dear Adam,
Thank you for all the great work. You are indeed empowering generations of developers.

Hi Adam,

I am developing a JavaEE 7 + Angular application with ~90% CRUD operations using JAX-RS + JWT. The other ~10% are long running tasks, where the progress / status should be visible in the front-end.

For this I can think to two possible solutions:

  1. Just start the task async and poll status from JAX-RS. Is very easy to implement, but causes additional overhead (http requests).

  2. Use Websocket to push status to clients. Less overhead, but it feels more low-level in comparison to JAX-RS and I need to think how to implement security ect. plus it is another technology making the project more complex.

Do you have any recommendations / experience which way to go?

Best regards,

If you use JsonObject as DTO like described here:

What are good approaches, if you have Entities and Inheritance? E.g. calling some super.somemethod() and adding more Attributes? Would such a Method return JsonObject or a JsonObjectBuilder? Other approaches?

I am interested in the course of Java EE microservices I have some doubts to clarify

In Java EE 7 Microservices, do you use Jenkins?

If I buy the course, can I ask you specific questions about microservices if you do not cover it in the course?

Hi, Adam. Thanks for the screencasts, they are awesome.
My first question:
I saw it several times in your screencasts but i didn't get the idea behind async rest requests (CompletableFuture, @suspended). When to use it? What is the use case? When to avoid it?

2nd question:
Do you have any experience with docker swarm? Any tips or avoid it?

Hi Adam,
We have REST app which has dependency on one of module that has EJB annotation. Wildfly tend to start too many threads for EJB because one of the jar has EJB annotation. How we can make it not to start EJB threads.
We use Wildfly 10

Hi dear Adam

  1. Do you think MVC is dying? both for back-end and front-end? (
  2. Do you use Reactive Programming? when? why? which use cases?
  3. Which of Java EE technologies should one learn for creating microservices with Java?

Is it possible do programmatically deploy/enable/disable/undeploy a JEE app on glassfish, payara, jboss or others? Via a REST api or something?

I could only find some info about JSR 88, but it's not clear to me which platform implements it. I understood that it was an optional requirement.

Hi Adam,

When working with microservice, what do you use to control the amount of simultanios access to a service? How do you do the load balance?

Can you recommend a good read on how to build applications with microservice?

Thanks for your help.
