Re: Regarding Javax/Jakarta support for applications deploying on TomEE 9.x / 10.x

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.
