Issue

• Getting this exception when deploying my war which contains a JAX-WS web service in JBoss EAP 6:

  Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: JBAS011030: Could not configure component com.jboss.examples.webservice.impl.ExampleWebServiceImpl

• com.jboss.examples.webservice.impl.ExampleWebServiceImpl looks like this:

  package com.jboss.examples.webservice.impl;
  
  @WebService
  public class ExampleWebServiceImpl {
  
    public ExampleWebServiceImpl(Example example) {
      this.example = example;
    }
    ...
  }
