Jakarta EE Survey 2020

At OmniFaces we poll the community from time to time about Java EE (now Jakarta EE) and related technologies. With the transfer of Java EE to Jakarta EE now almost completed, people are now starting to think about Jakarta EE 10 , the first Jakarta EE release after Java EE 8 having new featues. As such it's a good time to poll the community again. In the 2020 edition, there are 4 categories of questions again: Current usage of Java EE / Jakarta EE Servlet containers APIs related to Java EE / Jakarta EE The future of Jakarta EE Compared to 2018, we simplified some of the questions somewhat, omitting some of the less popular options to make it more manageable. We added questions about the future of Jakarta EE and MP together, the preferred Jakarta EE cadence, and generally updated the choices (such as adding Quarkus , which wasn't quite on the radar in 2018 and our own Piranha Cloud ). Jakarta EE provides the opportunity to revitalise and modernise Java EE, but i

Dynamically adding an interceptor to a build-in CDI bean

In Java EE's CDI, beans can be augmented via 2 artefacts; Decorators and Interceptors . Decorators are typically owned by the application code and can decorate a bean that's shipped by the container ( build-in beans ) or a library. Interceptors are typically shipped by a library and can be applied (bound) to a bean that's owned by the application. So how do you bind a library shipped interceptor to a library shipped/build-in bean? In CDI 1.2 and before this wasn't really possible, but in CDI 2.0 we can take advantage of the new InterceptionFactory to do just this. It's not entirely trivial yet, but it's doable. In this article we'll demonstrate how to apply the @RememberMe interceptor binding from the new Java EE 8 Security spec to a build-in bean of type HttpAuthenticationMechanism , which is from the Security spec as well. First we configure our authentication mechanism by means of the following annotation: @BasicAuthenticationMechanismDefin
