The war file does not start from the command line, how to fix it?

Question

Java

Hello. Help me figure out what I'm doing wrong, namely why it does not find the file javax.servlet.ServletException: File [/WarmStar_war/footer/footer.jsp] not found: I wrote a project, on servlets + Tomcat + JSP, and everything works fine if I deploy it to the IDE. There are no errors, everything is fine. And now I made a war file and I'm trying to deploy it to the server from the command line, but an error occurs. I don't even know how to fix it. If anyone knows, I would be grateful. Before that, I deployed war files more than once, it always worked :(

Perhaps this will be necessary: ​​I threw the war file into C:\Program Files\Apache Software Foundation\Tomcat 9.0\webapps , launched the startup.bat server, then the file name is WarmStar_war, then I call localhost:8085/WarmStar_war in the browser

javax.servlet.ServletException: File [/WarmStar_war/footer/footer.jsp] not found
