Realy nobody knows about this priblem? It's very important for me!

What do you mean by saying "more specific"?
I'm deploying it as a .war.
Here is the code of web-service:

import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.jws.soap.SOAPBinding;
@WebService
@SOAPBinding(style = SOAPBinding.Style.RPC)
public class WSJaxws {
@WebMethod
public String hello(String param){
String res = "";
res = "Hello "+param;
return res;
}
}
So I have only java code and web.xml file. When I start jboss it deploys this web-service and I here: http://localhost:8080/jbossws/services I have WSDL file. So everything seems to be fine. But when I restart jboss the web service dessapeares! So I need to rewrite web.xml file (before deploying I had one web.xml, but after deploying jboss changed it, but I know that i is normal). And if I rewrite web.xml as it was before first deploying my web service appeares!

Thank you very much!!!!! You helped me so! This was my mistake! I was deploying web service as an exploded war. Now I deplpyed it as a .war and everything works fine! Thank you a lot!!!!
