org.apache.axis2.AxisFault: http

[Anirban Das]

Hi,
Iam trying to access a service which is hosted on axis2 server. While running the client Iam getting the following error

log4j:WARN No appenders could be found for logger (org.apache.axis2.description.AxisService).
log4j:WARN Please initialize the log4j system properly.

The client code which I have generated using the "axis code generator" (eclipse plugin), is as follows

SimpleClient.Java -- which I have written myself

  package com.ttdev.client;
 
import java.rmi.RemoteException;
import com.ttdev.client.SimpleServiceStub.ConcatRequest;
import com.ttdev.client.SimpleServiceStub.ConcatResponse;
 
public class SimpleClient {
 
public static void main(String[] args) throws RemoteException {
  try{
SimpleServiceStub service = new SimpleServiceStub();
ConcatRequest request = new ConcatRequest();
request.setS1("Anirban");
request.setS2("Das");
ConcatResponse response = service.concat(request);
System.out.println(response.getConcatResponse());
  }catch (Exception ex){
  ex.printStackTrace();
  }
}

Hi Guys....
Well I got it . Its because the endpoint reference was not proper in wsdl. Once I changed it, it worked.

Thanks-
