Non Java client to Java JAX-WS Server

I been following this tutorial

http://ift.tt/2yZQeo9

I basically have a Java server running JAX-WS (SOAP Server), and in this implementation it includes the server and client. Now in this tutorial, the client and server share a common Interface that is able to make the service between them. But I wanted to know if there was a way to make this server work with other clients. I am doing a few clients in other languages so they do not have the same interface and functionality to call it. Is it possible to have other languages clients to send SOAP MTOM attachments to this Java server? or even this library at all?
