Jakarta EE 2020 Survey: which EE versions do people use?

-
At OmniFaces we have a survey running about Jakarta EE.

The first question is about which version of Java EE/Jakarta EE people use. While the final results are not yet in, let's take a sneak peek at the preliminary results.

Which versions of Java EE/Jakarta EE have you recently used? (select all that apply)

Java EE 8 is clearly taking the lead with Jakarta EE 8 in the second place. We see that J2EE 1.4 and Java EE 5 usage is very low, though there's still a sizeable amount of people using Java EE 6 (about 10%). When we zoom a little into the Java EE 6 figure, we learn that Java EE 6 users do for a large part use higher versions as well:
As Java EE 8 and Jakarta EE 8 are functionally identical, and differ mainly by their license, it's perhaps interesting to look at how these two relate to each other. For that we looked at the results where people said to only use Java EE 8, only use Jakarta EE 8, or said to use both of them:
As can be seen about half of the "8" users said to be using Java EE, with roughly 1 quarter using the Jakarta EE version and also roughly one quarter using both. It will be particularly interesting to see how these numbers will change in the future.

The Jakarta EE Survey 2020/2021 is still open. So if you haven't completed the survey yet, there's still time:

Jakarta EE Survey 2022

-
At OmniFaces we poll the community from time to time and again about Jakarta EE (previously Java EE) and related technologies. With the transfer of Java EE to Jakarta EE now fully completed and Jakarta EE 10 released , people are now starting to think about Jakarta EE 11 , the second Jakarta EE feature release. As such it's a good time to poll the community again. This year we're doing so in cooperation with OmniFish . In the 2022 edition, there are 4 categories of questions again: Current usage of Jakarta EE Servlet containers APIs related to Jakarta EE The future of Jakarta EE Compared to 2020, we simplified some of the questions once more; again omitting some of the less popular options to make it more manageable. We kept the questions about the future of Jakarta EE and MP together as this issue still isn't resolved. We also ask about the preferred Jakarta EE cadence. As Jakarta EE 10 is the first feature release, we haven't really established a cade

Implementing container authentication in Java EE with JASPIC

-
This article takes a look at the state of security support in Java EE 6, with a focus on applications that wish to do their own authentication and the usage of the JASPI/JASPIC/JSR 196 API. Update: the further reading section has been moved to my ZEEF page about JASPIC . This contains links to articles, background, questions and answers, and more.   Declarative security is easy In Java EE it has always been relatively straightforward to specify to which resources security constraints should be applied. For web resources (Servlets, JSP pages, etc) there is the <security-constraint> element in web.xml, while for EJB beans there's the @RolesAllowed annotation. Via this so called 'declarative security' the programmer can specify that only a user having the given roles is allowed access to the protected web resource, or may invoke methods on the protected bean. The declarative model has a programmatic counterpart via methods like HttpServletRequest#isUserInR

Counting the rows returned from a JPA query

-
Despite being almost ten years old, the JPA specification to this day has rather poor support for basic paging/sorting/filtering. Paging/sorting/filtering is used in a lot of (CRUD) applications where the result from a query is shown in a table, and where the user can scroll through the results one page at a time, and where this result can be sorted by clicking on any of the table column headers. In order to support this a number of things are generally needed: The total number of rows (or entities) in the full result must be known There should be support for an offset in the full result and a limit for the amount of rows that will be obtained The column (attribute) on which to sort must be dynamically added to the query Search expressions must be dynamically added to the query As it appears, only offset/limit is directly supported in JPA. A sorting column can only be added dynamically when using the overly verbose and hard to work with Criteria API. Search expressions
