If you're working with JAX-WS to create your web services, then you can access the HttpServletRequest object (and hence your HttpSession object) via the WebServiceContext.

@WebService(...)
public class MyService {
    @Resource
    private WebServiceContext ctx;

    private HttpSession getSession() {
        HttpServletRequest req = (HttpServletRequest) this.ctx.getMessageContext()
                .get(MessageContext.SERVLET_REQUEST);
        return req.getSession();
    }
}
