Java Web Services in Wildfly/JBoss & IntelliJ setup - web-services

Question

I have spent five days trying to get a simple HelloWorld web service to work in IntelliJ and this is my last chance to get it to work.
I am still very much a beginner in Web Services especially with Java, so please bare with me.
I have raised several tickets with JetBrains complaining about the outdated and vague documentation, the guys have been very helpful but have acknowledged there is a limitation, that it's not as straight forward to setup & the documentation is in fact outdated.
I am not getting a proper clean solution.
I was wondering if anyone uses the latest version of IntelliJ to build web services?
I am using Wildly, JBoss as the application server
I asked if I should be creating a Web App or a Rest Service as there is no user interaction since it will be a pure Web Service.
I have been advised to use a Rest Service, But I have created it both ways & attached the screenshots where applicable.
As a REST Service:
A simple project with one Web Service and a Web Method which returns a simple string:
Create a new project, choose Web App or Rest Service?
Choose XML Web Services? With CXF Implementation?
This is where I am a bit confused.
According to this link: https://developer.jboss.org/message/799428#799428
JBoss comes with its own implementation of Web Services JBossWS & It is recommended to use that instead of external Apache CXF?
So I'm not sure if I need to do anything, in this case it should work out of the box,
but it simply does not as I am getting exceptions:
This is the simple Project structure:
I have a basic web service class with the #WebService annotation:
package com.testwebservices.MyFirstWebService;
import javax.jws.WebService;
#WebService
public class MyFirstWebService {
public String firstWebMethod(){
return "Mama is the best!";
}
}
Now I am trying to expose this as a web service but its just not happening:
Now I am getting these options, If I choose anything other than the default Apache Axis I get a path incorrect issue,
See screenshot below with Default Apache Axis:
And when I choose CXF:
If JBossWS provides support for this out of the box, should it not work easily? Especially as most IDE's make this easy out of the box.
When I run the project nothing happens, there is no WSDL file, I went to the admin console, no mention of it. The documentation is vague.
As a Web App
When I choose the web app option and follow the same steps as above.
I get this exception:
Caused by: java.lang.ClassNotFoundException: org.apache.axis.transport.http.AxisServlet
What is the best way to setup a Web Services project in intelliJ?
I have no clue how to configure this or set it up.
Any help would be appreciated

I might encourage you to turn it around - use IntelliJ to build but get the general structure right first. Start with the Java code:
HeartBeatService.java
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
#WebService
#SOAPBinding(style = SOAPBinding.Style.RPC)
public class HeartBeatService {
#WebMethod
public HeartbeatResponse getHeartBeat() {
return new HeartbeatResponse("OK");
}
}
HeartbeatResponse.java
import javax.xml.bind.annotation.XmlRootElement;
#XmlRootElement
public class HeartbeatResponse {
private String status;
public HeartbeatResponse() {
}
public HeartbeatResponse(String status) {
this.status = status;
}
}
a pom.xml using the most recent things I could find:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

</dependency>
<dependency>
<groupId>com.sun.xml.ws</groupId>
<artifactId>rt</artifactId>
<version>2.3.1</version>
</dependency>
</dependencies>
</project>
and, lastly, a web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_1.xsd"
version="3.0">
</web-app>
Put this into a maven structure and make sure it compiles with mvn clean package and then import that into IntelliJ.
