How can I access the ServletContext from within a JAX-WS web service?

@Resource
private WebServiceContext context;

ServletContext servletContext =
    (ServletContext) context.getMessageContext().get(MessageContext.SERVLET_CONTEXT);

import javax.annotation.Resource;
import javax.jws.WebService;
import javax.servlet.ServletContext;
import javax.xml.ws.WebServiceContext;
import javax.xml.ws.handler.MessageContext;

import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

@WebService
public class MyWebService {


    // boilerplate code begins :(

    @Resource
    private WebServiceContext context;
    private WebApplicationContext webApplicationContext = null;

    /**
     * @return
     * @throws IllegalStateException
     */
    private WebApplicationContext getWebApplicationContext()
    		throws IllegalStateException {
    	if (webApplicationContext != null)
    		return webApplicationContext;
    	ServletContext servletContext =
    			(ServletContext) context.getMessageContext().get(
    					MessageContext.SERVLET_CONTEXT);
    	webApplicationContext =
    			WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext);
    	return webApplicationContext;
    }
}
