Not Found in ExternalContext as a Resource Error (Amazon Elastic Beanstalk / Spring Boot / JSF + Primefaces) - spring-boot

Question

I created an app using Spring Boot, JSF + Primefaces. I deployed it to Amazon Elastic Beanstalk, and set the environment variables that project needed to use.
When I tried to access my website, I got this error message:
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
/login.xhtml Not Found in ExternalContext as a Resource
Here is my Faces Config (as java class):
package com.jsf;
#SpringBootApplication
#Configuration
#ComponentScan("com.jsf")
public class HelloJsfApplication {
public static void main(String[] args) {
SpringApplication.run(HelloJsfApplication.class, args);
}
// JSF Configration Başlangıc
#Bean
public ServletRegistrationBean<FacesServlet> facesServletRegistraiton() {
ServletRegistrationBean<FacesServlet> registration = new ServletRegistrationBean<FacesServlet>(
new FacesServlet(), new String[] { "*.xhtml" });
registration.setName("Faces Servlet");
registration.setLoadOnStartup(1);
registration.addUrlMappings("*.xhtml");
return registration;
}
#Bean
public ServletContextInitializer servletContextInitializer() {
return servletContext -> {
servletContext.setInitParameter("com.sun.faces.forceLoadConfiguration", Boolean.TRUE.toString());
servletContext.setInitParameter("primefaces.THEME", "bootstrap");
// Primefaces client browser tarafında kontrol edilebilme örneğin textbox 10
// karakter olmalı vs..
servletContext.setInitParameter("primefaces.CLIENT_SIDE_VALIDATION", Boolean.TRUE.toString());
// Xhtml sayfalarında commentlerin parse edilmemesi.
servletContext.setInitParameter("javax.faces.FACELETS_SKIP_COMMENTS", Boolean.TRUE.toString());
// primefaces icon set için
servletContext.setInitParameter("primefaces.FONT_AWESOME", Boolean.TRUE.toString());
};
}
#Bean
public ServletListenerRegistrationBean<ConfigureListener> jsfConfigureListener() {
return new ServletListenerRegistrationBean<ConfigureListener>(new ConfigureListener());
}
// JSF Configration Sonu
}
my faces config file under webapp/WEB-INF folder:
<?xml version="1.0" encoding="UTF-8"?>
<faces-config xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"
version="2.2">
<application>
<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
</application>
</faces-config>
and as you see, all my xhtml files are under webapp folder:
my application.properties file (using java params):
server.servlet.context-path = ${CONTEXT_PATH}
server.port = ${PORT}
spring.datasource.url = ${SPRING_DATASOURCE_URL}
spring.datasource.username = ${SPRING_DATASOURCE_USERNAME}
spring.datasource.password = ${SPRING_DATASOURCE_PASSWORD}
spring.jpa.properties.hibernate.dialect = ${SPRING_JPA_DATABASE_PLATFORM}
# Hibernate ddl auto (create, create-drop, validate, update)
spring.jpa.hibernate.ddl-auto = ${SPRING_JPA_HIBERNATE_DDL_AUTO}
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=${SPRING_JPA_HIBERNATE_LOB_CREATION}
spring.datasource.driver-class-name=${SPRING_DATASOURCE_DRIVERCLASSNAME}
and here are java parameters that I defined on Amazon (I will not post db params for security reasons):
PORT=5000
CONTEXT_PATH=/
SPRING_DATASOURCE_DRIVERCLASSNAME=org.postgresql.Driver
...
and so on.
Really I run out of solutions. With same packaged jar, I deployed to Heroku with same environment parameters, and it works flawlessly.
Where I am doing wrong with Amazon Elastic Beanstalk?
Kind regards.

I found the problem.
Maven, does not add *.xhtml files inside "jar" package.
Here is the ss of decompiled version of jar packaging (with jd-gui)
..and here is the ss of war packaging:
so if you are think that you did everything correct during development and managing after, check the packaging type.
