在无状态EJB中获取客户端IP

Question

I have Stateless EJB WebService.

WS interface:

@Remote  
@WebService
public interface WSInterface{  
    @WebMethod  
    public String[] WSMethod(@WebParam(name="arg0") String arg0)
}

WS implementation:

@WebService
@Stateless
public class WSImpl extends GenericSessionBean implements WSInterface {
    @WebMethod
    public String[] WSMethod( String arg0)
    {
        return ...;
    }
}

And i need to get client IP in WSMethod. I tried to get it by this way (it works in "common" webservice):

@Resource  
private SessionContext ctx;  
public String[] getProperties() {  
    List propList = new ArrayList();    
    MessageContext mc = ctx.getMessageContext();  
    Iterator props = mc.getPropertyNames();  
    for (String prop = (String)props.next(); props.hasNext(); prop = (String)props.next())  
        { propList.add(prop); }  
    return propList.toArray(new String[propList.size()]);
}

But no success: there is no property with name REMOTE_ADDR in MessageContext .

Is there any way to get REMOTE_ADDR in @Stateless EJB?

Can you try to obtain a WebServiceContext instead of SessionContext with @Resource? I've no appropriate env to check it up right now
