element must contain a: 'faultcode' element

[Tibeau Jacques <j_...@hotmail.com>]

Hi

I'm testing a very simple SOAP test program.
But the very same program that once worked perfectly on 
SOAP 2.0 now returns the following error message with SOAP
2.2.

[Error message]
Exception in thread "main" [SOAPException: faultCode=SOAP-ENV:Client; msg=A 'htt
p://schemas.xmlsoap.org/soap/envelope/:Fault' element must contain a: 'faultcode
' element.; targetException=java.lang.IllegalArgumentException: A 'http://schema
s.xmlsoap.org/soap/envelope/:Fault' element must contain a: 'faultcode' element.
]
        at org.apache.soap.rpc.Call.invoke(Call.java:181)
        at TestClient.main(TestClient.java:20)

Is there any change I have to take into consideration in order to
migrate SOAP 2.0 source code to 2.2? Here's my test program.

/*******[My test web service]*********/
public class TestService {
   public int add(int num1, int num2) {
 return num1 + num2;
   }
}

/*******[My test client]************/
import org.apache.soap.*;
import org.apache.soap.encoding.*;
import org.apache.soap.encoding.soapenc.*;
import org.apache.soap.rpc.*;
import java.net.URL;
import java.util.Vector;

public class TestClient {

   public static void main(String[] args) throws Exception {

 Call call = new Call ();
 call.setTargetObjectURI("urn:testservice");
 call.setMethodName ("add");
 call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);

 Vector params = new Vector ();
 params.addElement (new Parameter("num1", Integer.class, args[1], null));
 params.addElement (new Parameter("num2", Integer.class, args[2], null));
 call.setParams (params);

 Response resp = call.invoke (new URL(args[0]), "");

 Parameter result = resp.getReturnValue ();
 System.out.println (result.getValue ());

   }
}

Any suggestion would be highly appreciated.

TIA,

j
