Use SOAP with dropwizard

        return a + b;

Hi,
Its giving this error: /WEB-INF/sun-jaxws.xml missing. Can you help.

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.
