Deploy SpringBoot application to JBOSS EAP 6.4

Question

I would like to create a simple hello world like REST Application in Springboot and deploy it to JBOSS EAP 6.4.

I have only one endpoint: GET request to /api/logparser and return a json

I could manage to build a war file and run locally without any problem. I think the problem is with my web.xml and context settings but I can't figure out what causing the error.

My project is the following:

build.gradle

plugins {
    id 'org.springframework.boot' version '2.1.3.RELEASE'
    id 'java'
    id 'war'
}

apply plugin: 'io.spring.dependency-management'

version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
} 

Application.java

package com.custom.logparser;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

My controller LogFileController.java

package com.custom.logparser;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class LogFileController {

    @RequestMapping("/api/logparser/getlog")
    public LogFile greeting() {
        return new LogFile("logFileContent");
    }
}

LogFile.java

package com.custom.logparser;

public class LogFile {

    private final String content;

    public LogFile(String content) {
        this.content = content;
    }

    public String getContent() {
        return content;
    }
}

I've created a ServletInitializer.java

package com.custom.logparser;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

}

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

</web-app>

dispatcher-config.xml

    <context:annotation-config/>

    <context:component-scan base-package="com.custom.logparser"/>

</beans>

I forgot to attach the error msg: http://s000.tinyupload.com/?file_id=05005994728105632903

It was loaded from the following location:

What did I miss?
