Use SOAP with dropwizard

AddNumbersService.java

package com.example.helloworld.resources;

import javax.jws.WebMethod;

@javax.jws.WebService(
        name = "AddNumbersPortType",
        serviceName = "AddNumbersService",
        targetNamespace = "http://duke.example.org")
@javax.jws.soap.SOAPBinding(
        style = javax.jws.soap.SOAPBinding.Style.DOCUMENT,
        use = javax.jws.soap.SOAPBinding.Use.LITERAL,
        parameterStyle = javax.jws.soap.SOAPBinding.ParameterStyle.WRAPPED)
public class AddNumbersService {
    @WebMethod
    public int Add(int a, int b) {
        return a + b;
    }
}

pom.xml

        <dependency>
            <groupId>com.sun.xml.ws</groupId>
            <artifactId>jaxws-rt</artifactId>
            <version>2.2.6-2</version>
        </dependency>

SoapBundle.java

    public class SoapBundle implements Bundle {
        @Override
        public void initialize(Environment environment) {
            environment.addServlet(new com.sun.xml.ws.transport.http.servlet.WSServlet(), "/SOAP/*");
            environment.addServletListeners(new com.sun.xml.ws.transport.http.servlet.WSServletContextListener());
        }
    }

sun-jaxws.xml

<?xml version="1.0" encoding="UTF-8"?>
<endpoints
        xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime"
        version="2.0">
    <endpoint
            name="HelloWorld"
            implementation="com.example.helloworld.resources.AddNumbersService"
            url-pattern="/SOAP/add"/>
</endpoints>

The missing "/WEB-INF/sun-jaxws.xml" is caused due to the WSServletContextListener trying to fetch the URL to sunJaxWsXml. Stepping through the code got me to the ContextHandler which checks the _baseResource value, which was never set when setting the servlet.
The most important bit is to set the resource base, without which the context would never find xml file, no matter where you place the file.

I am using dropwizard 0.7.1 and I add this to the run method of my Application class.

ServletEnvironment servlet = environment.servlets();
servlet.setResourceBase("/");
servlet.addServlet("/SOAP/*", new com.sun.xml.ws.transport.http.servlet.WSServlet());
servlet.addServletListeners(new com.sun.xml.ws.transport.http.servlet.WSServletContextListener());

And then ensure /WEB-INF/sun-jaxws.xml exists in the root directory.
