Right-clicking on the ear project will open the "Select deployment sever" window as usual but the WildFly 29 server is not in the Server list.
I manually added <org-netbeans-modules-maven-j2ee.netbeans_2e_hint_2e_deploy_2e_server>WildFly</org-netbeans-modules-maven-j2ee.netbeans_2e_hint_2e_deploy_2e_server> to the nb-configuration.xml file of the ear, ejb and web modules. It didn't make much of a difference. I still cannot run the ear project. Now, in the Run category of the ear project properties, Server is WildFly, but its Java EE Version is listed as Java EE 8 instead of 10; in the EJB module is even worse, it says Java EE 6; but in the Web module it does say Jakarta EE 10 Web.
