To get http session in the web service you should add a field to your class that will be populated with request context.

@WebService
public class MyService
{
  @WebMethod
  public int method(String value)
  {
    MessageContext messageContext = context.getMessageContext();
    HttpServletRequest request =
      (HttpServletRequest)messageContext.get(MessageContext.SERVLET_REQUEST);
    HttpSession session = request.getSession();

    // go ahead.
  }

  // A web service context.
  @Resource
  private WebServiceContext context;
}
