Web.xml configuration

<servlet-mapping>
        <servlet-name>javax.ws.rs.core.Application</servlet-name>
        <url-pattern>/rest/*</url-pattern>
</servlet-mapping>  

The rest service

@POST
	@Path("/myPath")
	@Consumes("multipart/mixed")
	@ResponseStatus(HttpStatus.OK)
	public String myService(@Context ServletContext servletContext, MultipartInput input) throws Exception {		
		logger.info("Processing /mixedMime");		
	}

The service does not do much at the moment. I just want to get it to work first.
It seems to be a problem with Jboss v7.1.0 because it works fine with Jboss 7.0.2.

The Jboss server starts up without any errors. I only see the error when i make a request to the server.
