(I am sorry about the springmvc-servlet.xml's position, I have locate it to under the resource library)
UPDATE - 1:
I am so sorry about it, there is a mistake when I post this snapshot, in my issue project, the web folder has no blue dot on it.See my answer I find the issue with it.
Update image:
So, where is the mistake?
EDIT
My hello.jsp:

EDIT
My tomcat deployment config:
EDIT -2

I think your tomcat deployment configuration is not all okay. your application context should be the context from where you are going to load your application and tell tomcat to dispatch all request within that context.
e.g. your Application Context: could be /helloApp. Now when you will start tomcat, your application would be loaded at localhost:8080/helloApp/. And this is your application root context. Now if you hit at localhost:8080/helloApp/mvc/hello, you are expected to see your content.

Put your springmvc-servlet.xml file in the WEB-INF and change lines of web.xml
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc-servlet.xml</param-value>
</init-param>
To
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/springmvc-servlet.xml</param-value>
</init-param>

There are couple of things to notice.
No project name specified in url
URL should be : http://localhost:8080/SpringMVCDemo/mvc/hello
Why are you mentioning two RequestMapping(mvc,hello) for only one page.You can remove #RequestMapping(value="/mvc") and keep #RequestMapping("/hello") on hello() method.
Update:
add load-on-startup in web.xml
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

At last, I find the issue I was lost. See my question -> UPDATE -1
No blue dot on it means Web Source Dictory is incorrect. See below image I find the issue.
So I delete the red directory, and then re-choose the web directory:
Then in my project, I can see the blue dot on web directory now:
And then I restart tomcat, I success:

i have tried #RequestMapping(value="/", method = RequestMethod.GET) and ("/main-menu"). Serched stack for similar errors and used sugestions but nothing works. Tried creatign different project from scratch... It's driving me nuts, seems everything is done by the book but still errors

Why is your spring-mvc-demo-servlet.xml file the exact copy of web.xml? Try changing spring-mvc-demo-servlet.xml to:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"

value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
OR...
In web.xml change the mapping as something similar as follows:
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/demo/*</url-pattern>
</servlet-mapping>
You will append demo in your url as http://localhost:8080/demo/

SOLVED
added extra mapping for method
#Controller
#RequestMapping
public class HomeController {
#RequestMapping("/home")
public String showPage(){
return "home-page";
}
}
added to web.xml
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
then lowered my language level to 13 since artifact could not deploy because of level 15 was unsupported by Spring (java.lang.IllegalArgumentException: Unsupported class file major version 59)
then i just call home page from browser
http://localhost:8080/SpringMVCdemo_war_exploded/home
Maybe this will help someone )

How do I automatically execute war files at Jenkins?

I am going to use Jenkins to execute the project automatically. The project is uploaded to github and succeeded in building War files using Jenkins. War file were moved to Tomcat's Webapps file, and Tomcat built it, but Tomcat runs properly, but projects don't run the project.
Setting
init_server.sh
echo "> Check the currently running spring server pid "
CURRENT_PID=$(ps -ef | grep java | grep tomcat | awk '{print $2}')
echo "$CURRENT_PID"
if [ -z $CURRENT_PID ]; then
echo "> No applications are currently running and will not be shut down."
else
echo "> kill -9 $CURRENT_PID"
kill -9 $CURRENT_PID
sleep 10
fi
rm -rf /usr/local/tomcat9/webapps/ji**t /usr/local/tomcat9/webapps/ji**t .war
echo nohup mv /root/jenkinsproject/deploy/*.war /usr/local/tomcat9/webapps/jinheeproject.war >> /root/jenkinsproject/logs/springtestprojectSys.log &
mv /root/jenkinsproject/deploy/*.war /usr/local/tomcat9/webapps/ji**t.war
sleep 10
cd /usr/local/tomcat9/bin
./startup.sh
echo "Execution complete."
application.yml
Run build in Jenkins, Follow the instructions in the Shell file, turn off the old Tomcat, and run the new Tomcat. And I type 'serverIP:8080' and the Tomcat server starts. But if I type 'serverIP:8080/helloworld', I see 404 error.
NOTE: I tested my project in the local environment. It was successful.
example: localhost:8080/helloworld
server.xml in cloud server
<Host name="localhost" appBase="webapps"

There was something I was missing. I forgot to inherit SpringBootServletInitializer and set it up.
application.java
#SpringBootApplication
public class Application extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}

Controller not invoked in spring-mvc application

I have a strange flow, when I'm trying to start the spring-mvc project, everything were building and starting correctly with localhost:8080 address, but it shows Apache Tomcat home page only and every request for example localhost:8080/login displays HTTP Status 404 – Not Found description:The origin server did not find a current representation for the target resource or is not willing to disclose that one exists. Strange here is that, when I'm trying to run same project in another machine (Ubuntu) it works perfectly, login page appears correctly and every requests works fine. Strange thing also here is that, this unexpected flow came first time for this machine.

I have fixed the problem, I just saw my artifacts and I have changed war artifact with exploded, now everything works fine.

In c turbo compiler first compile the code with zero error which is visible by pressing f9 then press ctrl+f9 for output then press alt+f5 the result will be visible on prompt window.

Tomcat 8.0 webapp deployment fails with NullPointerException

After upgrading my environment from Apache Tomcat 6.0.37 to 8.0.44 and Java from 1.7.0_45 to 1.8.0_131, one of my webapps will not deploy while the others run without issue.
My development environment is as follows.
Product Version: NetBeans IDE 8.2 (Build 201609300101)
Updates: NetBeans IDE is updated to version NetBeans 8.2 Patch 2
Java: 1.8.0_131; Java HotSpot(TM) 64-Bit Server VM 25.131-b11
Runtime: Java(TM) SE Runtime Environment 1.8.0_131-b11

User directory: C:\Users\heinzk\AppData\Roaming\NetBeans\8.2
Cache directory: C:\Users\heinzk\AppData\Local\NetBeans\Cache\8.2
When I attempt to run or debug my problematic webapp (which worked fine before these upgrades), I get the following server output.

Unfortunately the NullPointerException on the HashTable is not of much help.
The context.xml file is and always has been as follows.
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/Device_Monitor"/>
Obviously there's a property being retrieved for which the property name is null. However, I have no idea which it might be as the stack trace is truncated.
Is there a way to get the balance of the "cause's" stack trace?
Is it possible that the context.xml file is incomplete for this new environment?
A sampling of the web.xml is as follows.

After downloading and reviewing the pertinent the Tomcat source files as well as reading the javadocs and examining/comparing the context.xml and web.xml files between this projector and those that worked, I found that the following in my web.xml file was causing the issue.
<login-config>
<realm-name>Device-Monitor</realm-name>
</login-config>
After removing this login-config element my application started without issue.
It is odd to note that this did not cause an issue in my development environment under Tomcat 6.0 and Java 1.7.

Spring 3.2 MVC - Cannot match URL with Controller

My controller:

#RequestMapping(value = "/cCuenta")

return "crearCuenta";
}
...
}
My index.jsp:
<%# taglib prefix="sf" uri="http://www.springframework.org/tags/form" %>
<html>
<body>
<h2>BlaBla</h2>
<br/>
Crear Cuenta
</body>
</html>
Unfortunately, when I click the link, I get:
Status HTTP 404 - /deblan/cuenta/cCuenta
The browser tries to make a GET to http://localhost:8080/deblan/cuenta/cCuenta, but I cannot get in my controller. I debugged the controller and in fact is not entering there, so: Whats my newbie error?
Thanks in advance

If deblan is the context root then don't put it in the servlet mapping. You've got this url:
http://localhost:8080/deblan/cuenta/cCuenta
if you've deployed this app with deblan as the context root then:
http://localhost:8080/deblan
takes you to your app
/cuenta/cCuenta
now maps to your controller, so try:
<servlet-mapping>
<servlet-name>appServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
Which means http://localhost:8080/deblan + whatever comes after.
