Server apache-tomcat-9.0.55 at localhost failed to start -- no idea what I can do to resolve this-CodePudding

I am having a really big issue that I would really appreciate help on. Essentially, my class project that was a dynamic web page got completely messed up. I was able to recover some of the files, but have to start a new maven-archtype-webpage and restructure the project so I can copy and paste these files in.

I am trying to run a sample index.jsp page that says "hello world" on apache 9.0.55, and it is not working. I get an error that reads "Server apache-tomcat-9.0.55 at localhost failed to start.". The deeper error messages on the console say

'''
SEVERE: The required Server component failed to start so Tomcat is unable to start.

I was not having this issue at all before and I am honestly at a loss for what I can do. This is my POM.XML file

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

        </plugin>
    </plugins>
  </build>
</project>

and this is my web.xml

<!DOCTYPE web-app PUBLIC

 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>
</web-app>

This is how my project is currently structured

And this is what my java build path and target runtimes look like

Any help at all would be extremely appreciated. I will make sure to mark your response as correct and upvote. Thank you so much
