Newbie: SOAP Client

[Mitchell Shiller]

Just starting to write a web service client and I'm having trouble with  
the 1st example.

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import javax.xml.namespace.QName;

public class TestClient
{
   public static void main(String [] args) {
       try {
           String endpoint =
                    "http://nagoya.apache.org:5049/axis/services/echo";;
           Service  service = new Service();
           Call     call    = (Call) service.createCall();
           call.setTargetEndpointAddress( new java.net.URL(endpoint) );
           call.setOperationName(new QName("http://soapinterop.org/";,  
"echoString") );

           String ret = (String) call.invoke( new Object[] { "Hello!" }  
);

           System.out.println("Sent 'Hello!', got '" + ret + "'");
       } catch (Exception e) {
           System.err.println(e.toString());
       }
   }
}
This code compiles successfully.
When I run it in the command line I get the following;
java.lang.ExceptionInInitializerError:
  at org.apache.axis.client.Service.getAxisClient(Service.java:143)
  at org.apache.axis.client.Service.<init>(Service.java:152)
  at TestClient.main(TestClient.java:13)

a:39)
  at  
sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessor 
Impl.java:25)
  at java.lang.reflect.Method.invoke(Method.java:324)

Any help would be appreciated.

TIA
