IOException parsing XML document from ServletContext resource [/WEB-INF/spring-dispatcher-servlet.xml]

Receiving this error from console:
*org.springframework.beans.factory.BeanDefinitionStoreException:
IOException parsing XML document from ServletContext resource
[/WEB- INF/spring-dispatcher-servlet.xml]; nested exception is
java.io.FileNotFoundException: Could not open ServletContext resource
[/WEB-INF/spring-dispatcher-servlet.xml]*
That's the error I receive from:

I doing

to change the default context from springmvc, but it is not working. Already took some advice here to write a servlet-name tag to the file name-context.xml convention, same error.

You should try changing the servlet name. Expected Spring web-context metadata XML file name should servletname-servlet.xml, this was expected filename till Spring 4, not sure if it is changed in spring 5.
. As your servlet name is springmvc, filename should be springmvc-servlet.xml.
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>

Make your web.xml look like this, taken straight from the Spring documentation:
<web-app>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>

Angular 4 war file not running on JBOSS

I am new in angular and build a project with angular 4 as front end and JAVA Rest API as backend. I created a war file to deploy it on JBOSS but when I am trying to run the angular 4 war file on JBOSS but it gives me 404. It seems like some base-href issue in index.html. I tried with below base-href but nothing works:
<base href="/">
<base href="./">
<base href="/PROJECT_NAME/">
Please help me out in this.
Below is WEB.Xml for the same :

it opens the AdminLogin page but after that when I open other servlets it shows error as

Is the problem due to my web.xml file or something else?

However, this config in production environment is not working. If I go to
http://app.gtrwe.dev.corp/myapp/stats
I get 404 error. Also I have servlets in my web.xml
I am looking for help on how to set this up.

It seems that IBM WebSphere may encounter the ERROR 404 if no servlet is mapped to either /* or /monitoring, as mentioned here
