You can try to update to Jakarta EE 10 and Tomcat 10.1. I am not sure if it is working well. In these days I have no time to prepare a new template project for Jakarta EE 10 Servlet version. If you also encountered some issues when using Arquillain and Tomcat 10.1, do not file an issue on Arquillian Tomcat project.
