Failed to start 'webServerStartStop' spring boot app

After trying to run my app which main Class is present here:
#SpringBootApplication public class RappersInfo {
public static void main(String[] args) {
SpringApplication.run(RappersInfo.class, args);
} #Component
public class JspContextCustomizer implements TomcatContextCustomizer {
#Override
public void customize(Context context) {
JspPropertyGroup group = new JspPropertyGroup();
group.addUrlPattern("/*");
group.setPageEncoding("UTF-8");
context.setJspConfigDescriptor(new JspConfigDescriptorImpl(
Collections.singletonList(new JspPropertyGroupDescriptorImpl(group)),
Collections.emptyList()));
}
}
}
I get that error after trying to run that class:
org.springframework.context.ApplicationContextException: Failed to start bean 'webServerStartStop'; nested exception is org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat server

What can i do?
Tried almost everything what was in the internet.
Error happens after changing spring boot version from 3.x. to 2.7.6 (i want to deploy it with war file). Im not sure about my pom.xml. Maybe there is a problem with tomcat dependencies?

A similar error occurs if your address or port is incorrect / already used. This fixes the error in most situations, but a driver like the one mentioned above may cause the error.
Try changing port number from 8080 to something else. If that doesn't suffice, then one other instance I came across is as the following :
There was control software installed for the individuals Network interface controller (NIC) that allowed both ethernet and wifi to be used simultaneously. This was installed to supposedly improve gaming experience, but did not play nicely with tomcat in Spring. Once disabled the application was able to run as expected. It is described as follows :
This was a network interface Carr driver for an installed card. It will be different depending on card and driver installed - You can look at your drivers by looking at the Device Manager on windows.
Hope it helps you!!

Disable the Gamingservices service or go to the task manager and end the task of gamingservices and run again the application. or restart the computer.

Getting error while trying to run Spring Boot Application on Eureka Server.
Here I am trying to do Fault Tolerance in the Application.
I have created three Applications:
CitizenServer

In order to check whether the Fault Tolerance is working or not I have started EurekaServer and Vaccination Server.
Here I have closed the CitizenServer. In order to check the Fault Tolerance.

How to fix Eclipse Maven Package Error injecting constructor, java.lang.ExceptionInInitializerError

I am trying to build a simple Servlet, that should only return me the content that was sent with the request. It does not build though I did not do anything different then before qhen I made another Servlet a year ago (that does not compile anymore either).
I do not understand the Problem as I haven't made anything different then before. Has anyone an Idea what it might be?
I suspect it might have something to do with the maven-war-plugin as it sais in the errors something about an maven-war-plugin:2.2, which seam odd to me as I am not using that version. Does someone know how I could enforce the use of the current version I put in the pom.xml, to see if that would solve it?
It sais:
Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.2:war (default-war) on project LoginTest: Execution default-war of goal org.apache.maven.plugins:maven-war-plugin:2.2:war failed: Unable to load the mojo 'war' in the plugin 'org.apache.maven.plugins:maven-war-plugin:2.2' due to an API incompatibility: org.codehaus.plexus.component.repository.exception.ComponentLookupException: Cannot access defaults field of Properties
After this Error I get:

As pointed out by khmarbaise, my problem was that I had the plugins listed as dependencies in the pom file. Adding them correctly as plugins and removing their information from the dependecies fixed it for me.

Problem is with the javax.servlet, Spring boot has this dependency built in already with a version that is compatible with spring boot code
The problem you have is that you have included javax.servlet in pom file making spring fails since certain classes are not found in the runtime hens Caused by: java.lang.ClassNotFoundException: javax.servlet.DispatcherType
To resolve this remove javax.servlet dependency, that will re-activate the one shipped in Spring Boot again

Had to import javax.servlet.DispatcherType, now its working.
