holding ServletContext reference in ServiceLifecycle.init()

["Jung, Eric (Contractor)" <ej...@russellmellon.com>]

If I need access to ServletContext from a service, does anyone see a problem
doing this:

/* Calculator exposes a service called Add */
public class Calculator implements javax.xml.rpc.server.ServiceLifecycle {

  ServletContext sc;

  public void init(Object context) {
     ServletEndpointContext sec = (ServletEndpointContext)context;
     sc = sec.getServletContext(); //hold ServletContext reference
  }

  //The Add service
  public void add(String str) {
    //use sc here
  }
}

instead of this:

public class Calculator {
 
  //The Add service
  public void add(String str) {
    MessageContext mc = MessageContext.getCurrentContext();
    ServletContext sc = ((HttpServlet)
mc.getProperty(HTTPConstants.MC_HTTP_SERVLET)).getServletContext();
    //use sc here
  }
}

Which is a better approach?

TYIA,

HEre is how to do that from a BasicHandler


  public void invoke(org.apache.axis.MessageContext messageContext) throws
org.apache.axis.AxisFault {
        try {
            Message reqMessage = messageContext.getRequestMessage();
            SOAPEnvelope env = reqMessage.getSOAPEnvelope();
//            Element envElement = env.getAsDOM();
//            String strSOAPBody = XMLUtils.ElementToString(envElement);
//            StringBuffer logStr = new StringBuffer();
//            logStr.append(strSOAPBody);
//            System.out.println(strSOAPBody);
            HttpServletRequest request1 = (HttpServletRequest)
messageContext.getProperty(HTTPConstants.MC_HTTP_SERVLETREQUEST);
            HttpSession re =  ((HttpServletRequest)
messageContext.getProperty(HTTPConstants.MC_HTTP_SERVLETREQUEST)).getSession
();
