Hi, I've been working for quite a long time on TomEE 9.x, and it's been more challenging and painful than I was expecting. I thought it would be good to give you some sort of status.
I created a PR for the work. As a reminder, since Java EE moved to Eclipse to become Jakarta EE, we had a switch from javax.* namespace to jakarta.* namespace. This is an impacting change, since all applications and applications servers are built on top of it. In TomEE, we decided to do that change in TomEE. We had previously a bytecode change approach like an application could do. It worked and we were able to get certified. But it had a lot of limitations, so we had to do the migration in the code and fix all compatibility issues. Here is the PR https://github.com/apache/tomee/pull/814 It has 90+ commits and nearly 5000 files touched (added, removed, updated). I understand it's a lot and it makes it almost impossible to review. But I did not see much approaches in this scenario to create smaller PRs. I created a Jenkins build though available at https://ci-builds.apache.org/job/Tomee/job/master-build-quick-9.x/ It makes it possible to track the progress. There have been steps forward and steps backward. All the code does not sit under TomEE, we use a bunch of third party projects and libraries. I have been able to contribute, publish jakarta compatible versions and get releases for some of them (Jakarta EE APIs Uber jar, Geronimo Connectors and Transaction Manager, Geronimo Config, Health, Metrics, OpenTracing, OpenAPI. OpenJPA, BVal, and OpenWebBeans will be released soon. The big parts is CXF, and ActiveMQ. I had to get them done in TomEE and update all group/artifact ids. It's under deps, alongside with SXC, DBCP, and others. In terms of removal, I tried to remove old stuff like SAAJ Axis 1 integration, JAX RPC, Management J2EE and a couple of other old things. A lot of other libraries got updated to their latest version when available in the new jakarta namespace. I'm starting to get all the build stable and many modules are passing now, including all CXF webservices, OpenEJB Core, and others. I can get a build and run TomEE. Goal is to get a green build asap so we can start working on TCK. The "quick" build is now green. Working on the full build. I'll soon be creating a branch for TomEE 8.x maintenance and merge the PR. I'm hoping we can then have small PRs or at least more people working in parallel. -- Jean-Louis Monteiro http://twitter.com/jlouismonteiro http://www.tomitribe.com
