Hi Adam, How do you achieve a dynamic creation on Message Listener in JEE7? (The MDB listen only a queue/topic!) I want to create dynamic Listeners for queues read from a file. My queues are configured in a remote server standalone (Artemis) not in Wildfly configuration file (xml). With Spring I can dynamic create DefaultMessageListenerContainer and set some Message Listeners for this list of queues. Do you have any ideia? I don want deploy a new version of the application every time I add a new queue in my standalone server. Is like the @JMSDestinationDefinitions but programatically.

Hi Adam i have a cuestión i implement Java rest app web, i need implementación session time out , sso( single sign on), with tokens , i can implement with REDIS for tokens validación, session y session time out ? But Jwt is not a solution. How web app normal works

Hi Adam,

Thanks a ton for doing the AirHack QA! It provides practical answers to all the "real life" questions, putting aside all the hype.

I have a lot of questions and they can be all over the place, but please bear with me:

  • What factors do you consider before choosing server-side rendering frameworks like JSF or JS frameworks like React?
  • Are the patterns in your JEE pattern book, 'JAVA EE Patterns'(written for JEE 6) still hold true for JEE7 and upcoming JEE8?
  • Your JAVA image for Docker containers uses openJDK instead of Oracle JDK. Any particular reason?

I have more questions, but I will give others a chance to ask few as well :)

Hello Adam,

Congratulations on the new WebStandards Online Workshop.

  1. When you are using keycloak , how do you handle additional user properties?

    • Would you bother editing keycloak configuration to provide additional properties , or would you have a 'users' microservice (with it's own database) that communicates with keycloak (another microservice) and you would map each user from 'users' microservice with Keycloak User's ID ?
  2. Which is the best way to handle 'money' variable in Java(BigDecimal ?) and which SQL data type to choose ?

    • I'm using JPA - Hibernate and MySQL

Thanks in advance.

Hey Adam,

EJB question here:
I have 2 .ears deployed on the same JBOSS, each containing a .jar with EJBs (same .jar, maybe different versions of it).

When a resource in .ear A uses an EJB (simply injects it with @EJB, nothing else), where will it take the EJB from? From its own .jar, which it has as a dependency, or from the .jar which comes as a dependency to .ear B?

I think another way of putting the question is: Is the EJB container local, per application, or global, per server? Because if it's global, then for sure the scenario above poses a problem: we may have 2 versions of the same EJB and not knowing which one is going to be used when.
