Regarding Javax/Jakarta support for applications deploying on TomEE 9.x / 10.x
Hi Team,
We are in the process of evaluating TomEE 8.x to TomEE 9.x / 10.x upgrade..
I have a couple of queries before we can take any wise decision -
1) We are running the application on JDK 17 and compiled our code with JDK8
- Does TomEE 9.x have any issues if the application code is compiled with
JAVA 1.8.x ?
2) We are having many references to *javax.** within the application and
also using a bunch of third-party jars which are javax compatible, our plan
is to move to TomEE 9.x and check if it works without *javax.* *to*
jakarta.** migration within our code ?
Is Jakarta namespace migration mandatory if deploying the application on
TomEE 9.x ?
The above would include migration of third-party jars as well based on the
core container for us (i.e., TomEE 8.x / 9.x).
3) TomEE 9.x seems to be using Tomcat 9.x that works on javax namespace so
our next proposal is to see, If TomEE 9.x works with Tomcat 10.x or Is it
tightly coupled with Tomcat 9.x only ?
Please advise.
Thank you in advance!
Regards,
Nikhil Somasani

Thank you so much Jean-Louis.. that clear's most of our queries for
migration.
Concerning TomEE 9.x, there was a confusion with *Jakarta EE 9.x *instead
of *Tomcat 9.x* and yes (*TomEE 9.x *includes *Tomcat 10.x) - *This
information clears all the roadblocks for upgrading the majority of
third-party components.

Not as far as I am aware of. If you have an issue, it should be definitely
fixed.

javax based applications will only deployed to TomEE up to 8.x
From 9.x onwards, you must migrate your application to jakarta namespace.

Correct. And that's usually harder to manage external libraries than it is
to convert your own source code to jakarta.

That's incorrect.
TomEE 9.x uses Tomcat 10.x
See https://github.com/apache/tomee/blob/tomee-9.x/pom.xml#L205
Tomcat 10.x is also jakarta compatible.
And yes TomEE is tightly coupled with Tomcat. This is because we want to be
Tomcat and we want to be very deeply and well integrated with it.
