deploy .war file in Tomcat 10

Question

I am trying to deploy .war file in Tomcat 10.0, it is not a servlet app.

First of all I tried with this example: https://tomcat.apache.org/tomcat-5.5-doc/appdev/sample/ I downloaded sample.war file and dropped it in C:\Program Files\Apache Software Foundation\Tomcat 10.0\webapps, it worked.

Then I've created myApp.war via IntelliJ and dropped it in C:\Program Files\Apache Software Foundation\Tomcat 10.0\webapps

But when I acces to http://localhost:8080/myApp/ I get 404

Any idea? I am very newbie on this field, I am quite lost, any help will be appreciated!

Thanks
