Class load error when deploying tomcat + war container in Kubernetes

I have an image based on tomcat jre11 with the activemq war for geoserver. I can run the image in my local docker or on my EKS cluster no problem. However when I run it on another managed Kubernetes cluster the war file fails to deploy.
I copy-pasted the full pods' log further down below... As you can see the error appears to be a class loading type of issue?
ERROR ContextLoader - Context initialization failed
java.lang.IncompatibleClassChangeError: class org.springframework.asm.commons.EmptyVisitor can not implement org.springframework.asm.ClassVisitor, because it is not an interface
What's really puzzling is that exact same image run perfectly fine in another k8s cluster! How is that possible?

This is because the Spring-data is getting the old spring-asm.
You should check all dependencies with Maven’s command mvn dependency:tree
Ways of fixing it:-
Define the Spring data dependency AFTER the Spring related
dependencies. Maven transitive dependencies will fetch the correct
Spring dependencies automatically.
According to a similar issue here
About java.lang.IncompatibleClassChangeError
Doc
In simple terms:-
It only happens when trying to load a class that is known to be derived from an interface which is registered as a class. If there is no such load even if the offending class exists in the classpath their will be no exceptions. This is mainly due to the fact that java loads class if there is use for such a class in runtime or customarily by the programmer. In this case it implies that either the class in the context of the exception is either loaded customarily or used while in the other context not. This is basically the explanation.

localhost:8080 shows error 404-not found
I just installed tomcat server on my windows 10 pc. Now when i run startup.bat i get this error.
All enviornment variables are set
JRE_HOME: C:\Program Files\Java\jre1.8.0_231
CATALINA_HOME: C:\Program Files\Apache Software Foundation\Tomcat 9.0
windows services list also shows apache tomcat 9 running.

I am able to generate same error after replacing Tomcat 9 servlate-api to tomcat 8 this show that there version mismatch of servlet-api.
so, either download new tomcat 9 from tomcat site or place correct version servlet-api to path
x:\apache-tomcat-9.0.30\lib

Caused by: java.lang.NoSuchMethodError: javax.servlet.ServletContext.getClassLoader()Ljava/lang/ClassLoader;
at org.apache.tomcat.util.scan.StandardJarScanner.doScanClassPath(StandardJarScanner.java:246)
Looks like servlet-api.jar is missing or there is a version mismatch. Try doing a fresh install after removing all directories. Follow https://tomcat.apache.org/

Tomcat: change port from 8080 to 80 not working

I have a tomcat server running on DigitalOcean VPS. The server.xml file looks like this:
<?xml version="1.0" encoding="UTF-8"?>

</Host>
</Engine>
</Service>
</Server>
I edited the <Connector> part to make the server run on port 80 instead of 8080. Before the changes I could access the server using IP:8080 address, but now I can't access it at all - whether I use IP:8080 or IP:80 or IP.
I restarted my tomcat using shutdown.sh and startup.sh and restarted my droplet using sudo reboot, but it changed nothing.
I checked the firewall using sudo ufw status verbose and it gave an inactive status.
EDIT:
I tried the shutdown.sh -> startup.sh -> sudo reboot route again and here is the catalina.out since the shutdown.sh command:

With help of #ernest_k I managed to find the problem. The problem was that the port was never truly changed from 8080 to 80. It happened because although I was connected as a root user to the VPS, the tomcat automatically switched to non-root user tomcat, because of /etc/systemd/system/tomcat.service file:
[Unit]
Description=Apache Tomcat Web Application Container
After=network.target
[Service]
Type=forking
Environment=JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64/jre
Environment=CATALINA_PID=/opt/tomcat/temp/tomcat.pid
Environment=CATALINA_HOME=/opt/tomcat
Environment=CATALINA_BASE=/opt/tomcat
Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'
Environment='JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom'
ExecStart=/opt/tomcat/bin/startup.sh
ExecStop=/opt/tomcat/bin/shutdown.sh
User=tomcat
Group=tomcat
UMask=0007
RestartSec=10
Restart=always
[Install]
WantedBy=multi-user.target
So I changed a User=tomcat to User=root, restarted everything and now it works fine!

port no 1 to 1023 is reserved for the system use may be because of that you are not able to change the port no to 80.

Deploying Web App Manually on TomCat

I am trying to deploy a web app manually on Tomcat.
I have created a "myapp" folder in webapps folder with following files and folders:-
1) myapp\WEB-INF\index.html
2) myapp\WEB-INF\classes
3) myapp\WEB-INF\lib
4) myapp\WEB-INF\myapp-servlet.xml
5) myapp\WEB-INF\web.html
But I am getting the following exception :-
java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/myapp]]
at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:756)

I linked my classes folder in tomcat and rest of the files I just copy pasted. I was able to run this like some time back. But I am not getting what i am missing. Is it build.xml? Thanks!

You can start by cheking if you are using jdk path for the runtime enviroments, you must use jre path. Make sure that tomcat uses the same java version as your application.

Based on previous answer I did following things :-
1) Added pom.xml instead of lib folder
2) Changed the servlet name in the web.xml
Deployed the above web app successfully on tomcat.
Update :
It's not pom.xml that makes tomcat fail but some jars that conflicts with tomcat lib on removing those everything is fine.

Tomcat: War file deploys locally but not on online server [duplicate]

This question already has answers here:
java.lang.IllegalArgumentException: The servlets named [X] and [Y] are both mapped to the url-pattern [/url] which is not permitted

I've a war file of a web app that runs on tomcat 8 via netbeans as well as tomcat 8 independently without IDE. But if I try to run the same war file on tomcat 8 installed in an online server(I'm using koding.com vm for the purpose), I'm getting the following log in catalina.out:

Caused by: java.lang.IllegalArgumentException: The servlets named
[register] and [com.whiteboard.servlet.register] are both mapped to
the url-pattern [/register] which is not permitted
This Error clearly states that same url-mapping is mapped to two Servlets.
Modify your web.xml and you are good to go.
