I don't seem to find something online expect the fact that java ee stops and we can't use name right so we renamed it as Jakarta ee and that's ok but I still don't know if there any difference between Jakarta ee and java ee 8 why should I use Jakarta ee and not java ee 8 and on top of that I can't figure out where can I find Jakarta ee to start using it
It is just the specification for Java Enterprise Edition going forward.
Oracle moved the JCP process to the Eclipse Foundation, but since Oracle still owns the Java trademark, Eclipse renamed it to Jakarta EE.
