What is the name of the design pattern where I dynamically pick the correct implementation based on data?
Originally I picked the correct User implementation, based on domain and realm data from the Java EE server. However that was company code, so I had to rewrite the example with numbers.

How to unit test methods together with its constraint validators (which some should be mocked out)?
My app has a service layer which is composed by CDI applications scoped beans: When a method gets called, an interceptor (in my case BValInterceptor.class from Apache BVal) checks if the method contract is respected by checking the annotations and validating the parameters accordingly.

CDI events fire() create new observers instances
I’m writing a JavaFX application (JavaSE) with CDI (Weld). I’m trying to use CDI Events to replace the awful event system of JavaFX (JavaFX Properties). I was able to let CDI create my JavaFX controllers properly. It means that when a FXML is loaded, the controller is created by CDI (using FXLoade…
Can @Inject be made optional in JSR 330 (like @Autowire(required=false)?
Spring’s @Autowire can be configured such that Spring will not throw an error if no matching autowire candidates are found: @Autowire(required=false) Is there an equivalent JSR-330 annotation? @Inject always fails if there is no matching candidate. Is there any way I can use @Inject but not have the fra…
