So, I think this might be a trivial problem but am currently at a loss.
I created a vanilla Tomcat server on Ubuntu (tomcat-10.0.4).
It is configured to run on port 80 and I can see the Tomcat manager fine.
Tomcat runs under its own user (tomcat) with full rights to its installation folder (/opt/tomcat)
Magnolia was downloaded (magnolia-dx-core-demo-webapp-6.2.6.war)
The war file was renamed to magnoliaAuthor.war and the tomcat user made the owner of the file.
When moved to the webapps folder the war file is automatically extracted.
The `ls -li` command yields:
1283171 drwxr-x--- 6 tomcat tomcat 4096 Mar 29 15:12 magnoliaAuthor
256320 -rw-r----- 1 tomcat tomcat 486185464 Jan 27 17:37 magnoliaAuthor.war
So far so good. But in the Tomcat Web Application Manager I see the application is not running. I click `Start` and the application fails to start with only the following message:
"FAIL - Application at context path [/magnoliaAuthor] could not be started"
The logs are not helpful.

With the above information I don't see anything to point me in the right direction.

Hi,
I don't think Magnolia still supports tomcat 10 or more specifically servlet 5.0 [1]. The latter moved servlet-api from javax.servlet to jakarta.servlet which causes the exception you see in catalina.out and requires changes in magnolia sources. Switch to 9.x and you should be fine.

Looks like this was exactly the issue. I raised the problem through an official support channel to confirm. Hopefully the newer platform will be supported in the near future.
