How to isolate the war classloading in wildfly 10. Getting a visibility issue for org.apache.cxf.enpoint.Client class

I am trying to deploy a war which has a JAX-WS client for SOAP services in Wildfly 10.1.0.Final. When I am trying to get the port for the webservice the delegate interface in javax.xml.ws.Service automatically going to apache cxf implementation of getPort() method.

When its internally try to create a proxy connection, I am getting a IllegalArgumentException as org.apache.cxf.enpoint.Client is not visible to classloader.

I have read the documentation and the classloading hierarchy of wildfly. Wildfly has a cxf-core.jar(3.1.6) and my war also have cxf-core.jar(3.1.7). My estimation is that it is trying to access the cxf-core.jar from wildfly and throwing classloading issue.

JBOSS has different meta files for altering the flow of normal class loading like jboss-web.xml, jboss-classloading.xml etc. My query which meta file should I use to resolve this visibility issue of classloader.

What will be the meta file, what is the content and what are the references that I need to write in contents(say war name mywar.war).

Error trace that I am getting :

You need to exclude the JBoss web service subsystem from your deployment by adding a jboss-deployment-structure.xml file to the WAR's WEB-INF folder.

Source: Exclude a Subsystem from a Deployment

Here is a an example which would do it.

    <?xml version="1.0" encoding="UTF-8"?>  
    <jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">  
      <deployment>  
        <exclude-subsystems>   
          <subsystem name="webservices" />
        </exclude-subsystems>
        <dependencies>
          <module name="org.apache.cxf" />
          <module name="org.apache.cxf.impl" />
        </dependencies>  
      </deployment>  
    </jboss-deployment-structure>
