Problems with web services (org.apache.axis.client.Service.getAxisClient)

Posted: Jun 28, 2006 4:31 AM

I have a problem in my webapplication axis. I try to access a web service...

/***********************CLIENT***********************/
package ejercicio1;

import java.net.MalformedURLException;
import java.rmi.RemoteException;
import javax.xml.rpc.ServiceException;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

public class ClienteWSDD_2 {

public static void main(String[] args) throws ServiceException, RemoteException, MalformedURLException{

String endpoint = "http://localhost:" + 8080 + "/axis/services/Hola_D";
Service service = new Service();//the problem starts at this line
Call call = (Call) service.createCall();
call.setTargetEndpointAddress( new java.net.URL(endpoint) );

Object ret = call.invoke("sayHelloTo", new Object [] {});
System.out.println(ret);

/*****************************************************/

But I can't run it:

Exception in thread "main" java.lang.ExceptionInInitializerError
at org.apache.axis.client.Service.getAxisClient(Service.java:103)
at org.apache.axis.client.Service.<init>(Service.java:112)
at ejercicio1.ClienteWSDD_2.main(ClienteWSDD_2.java:26)
Caused by: java.lang.NullPointerException
at java.util.Hashtable.get(Unknown Source)
at org.apache.commons.logging.LogFactory.getCachedFactory(LogFactory.java:495)
at org.apache.commons.logging.LogFactory.getFactory(LogFactory.java:264)
at org.apache.commons.logging.LogFactory.getLog(LogFactory.java:394)
at org.apache.axis.components.logger.LogFactory.getLog(LogFactory.java:37)
at org.apache.axis.handlers.BasicHandler.<clinit>(BasicHandler.java:43)
... 3 more

- The service is very simple...

/***********Server****Hola_D.java*****************/
package deploy_1;
public class Hola_D{
public static void main(String[] args)
{
System.out.println("Hoolaaaaaaaaaaaaa");
}
public String sayHelloTo()
{
return "Hello";
}
}
/**********************************/
And to deploy the service:

<deployment xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<service name="Hola_D" provider="java:RPC">
<parameter name="className" value="deploy_1.Hola_D"/>
<parameter name="allowedMethods" value="*"/>
</service>
</deployment>

I can see "http://localhost:8080/axis/services/Hola_D?wsdl" without any problem.

Thanks in advance!
