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

Custom authorization rules on IBM Liberty

Last month we presented a way how a Java EE application can provide custom rules for authorization . The code shown in that article was developed and tested using Payara . We're now going to look at how the code can be used on some other servers, starting with IBM's Liberty. Liberty has a highly modularised architecture and features a rather amazing way by which and end user can compose the runtime. By means of its server.xml file, a Liberty user can add or remove nearly every individual feature that Liberty has independently. The Liberty core system keeps track of the dependencies of each module representing such feature and adds or removes its dependencies accordingly (in a way not quite unlike what a tool like Maven does at build time). All this power does come at some price. For Liberty the JACC provider which is needed to implement the logic behind the custom authorization rules has to be turned into a Liberty specific module (called a user feature), which is quite a
