IntelliJ MVC Server Context initialization failed

Following a udemy course, I have encountered this issue, to which the answer I didn't find anywhere.
I've had issues with the model class, but that seems to be working now.
URL pattern is fixed, by just being a /
for webmvc i have updated the dependency to be 4.3.6.RELEASE
Code itself and the server was running just before adding changes to the controller, enabling it to pass message value to the model.
Any help would be greatly appreciated.

And lastly, the project structure:Image of project structure

As per advise
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.3.6.RELEASE</version>
Was changed to:
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.3.23</version>
Now it works.
Cheers!

Webapp deployment fails after maven implemtation

I am facing issue in deploying my web app on tomcat after I have implemented Maven for dependency management. Before Maven implementation, it was a plain web app where every thing was used to be managed manually. I started upgrading app with frameworks for learning and decided to implement Maven for dependency management as first step.
While I implemented Maven and everything works fine from eclipse, it does not work when I deploy war file on a standalone tomcat.
I am defining path to my app in Catalina properties against shared.loader property and a context xml under Catalina folder within tomcat conf directory (see the directory structure below)
directoryStructure

Following are the relevant entries from Tomcat configuration

With the same setup if I rename "WebApp" to "WebApp_New" and "WebApp_20220102" to "WebApp" (basically the old app) then everything works fine without any problem.
I have compared all configuration files within "WebApp" folder, e.g. log4j2.xml, web.xml etc. but not able to figure out the problematic entry. I have also tried replacing jars from old app (WebApp_20220102\WEB-INF\lib) to the new app's lib folder but nothing changed. I continue to get the issue in deploying new app, but if I rename WebApp folders and launch old app, it works just fine.

You're missing the log4j implementation JARs. "lib folder with Maven" lists the log4j-api JARs, but not the log4j-core implementation. Add
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.17.1</version>
</dependency>
to the pom.xml

Since I was able to run the app when deployed on tomcat within Eclipse, I started looking at differences in configuration of standalone tomcat and that within eclipse. I did not find any differences or I matched the config of both servers.
After this I decided to look at each and every file within Web App folder and I found difference in size of .class files. I realized that when eclipse is deploying it on the internal tomcat, it is compiling the output to the target folder but when this is done using maven, class files are generated in /target/classes folder. This folder is copied to the /WEB-INF/classes folder at the time of packaging.
In my case, I do not know how, I had classes folder within the project's WebContent/WEB-INF/classes directory. This directory had very old version of classes, with very small size (3KB Vs 10KB). I removed the classes directory from the WebContent/WEB-INF folder and maven started copying target/classes folder to WEB-INF/classes. This resolved the issue.

HTTP Status 404 – Not Found while app is running

I have a problem with my spring app. While I run it, I am getting below exception:
It had worked correctly, but app didn't see changes in .jsp files and loaded the same page every time.
I faced with this problem in the past? but unfortunately I couldn't resolve this, and recreated project.

Maybe there is a problem with artifacts or tomcat configuration, because I changed it while tried resolve this error.

Pom.xml updated too above.

You can try maven tomcat plugin
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<port>9000</port> //Configure port number
<path>/spring5-webmvc-demo</path> //Configure application root URL
</configuration>
</plugin>
Then you can do a build mvn clean install and then mvn tomcat7:run

At least I resolved my problem. As told M. Deinum I have moved an web.xml, view, and spring-mvc-demo-servlet.xml to WEB-INF, because I have:
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/" />
<property name="suffix" value=".jsp" />
</bean>
Then I regenerated an Artifacts.

HTTP Status 404 – Not Found during hello world

Im the beginner at web apps.
I tried to run the first application, but error occured.
I copied everything from the book, there everything works, at my place not...typically. I have been looking for hours for solution. Couldn't find.
I'm using 10.02 java, Apache Tomcat/9.0.12 and IntelliJ.
Here how my files structure looks like:
That is how configuration of Tomcat looks like:
HomeController
package com.packt.webstore.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
#Controller
public class HomeController {
#RequestMapping("/")
public String welcome(Model model) {
model.addAttribute("greeting", "Hello");
model.addAttribute("tagline", "In the internet");
return "welcome";
}
}

Stacktrace
(i had to paste it on pastebin, because question is too long)

Config you pom properly, your current configuration is creating jar file, instead of war, and you don't have maven war plugin to put your web resource (jsp, web.xml, etc) into the war file.

Put your WEB-INF folder under a root folder, for example webapp/WEB-INF, here webapp folder is in same level as src folder
Rename your DefaultServeletservlet.xml to
DefaultServelet-servlet.xml
Modify web.xml file to config DefaultServlet.
<servlet>
...
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/DefaultServlet-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
After all of this, deploy it, then you should see something like this:

The problem with the above is that you have named your servlet configuration file as DefaultServletservlet.xml.
Instead you should rename it as DefaultServlet-servlet.xml. While checking for the xml configuration spring matches the filename with -servlet as a suffix. As it is not able to find DefaultServlet-servlet.xml, hence the error.
