Axis call strange behavior

[angeloimm <an...@libero.it>]

Hi all; i have a strain behavior in Axis Call; well if i use this client:

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.message.SOAPBodyElement;
import org.apache.axis.message.SOAPBody;
import org.apache.axis.utils.XMLUtils;
import javax.xml.rpc.ServiceException;

import java.util.Vector;
import org.w3c.dom.Document;
import javax.xml.namespace.QName;

import org.apache.log4j.Logger;
import java.net.URL;
import java.net.MalformedURLException;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
public class SimpleAxisClient {

    private static final Logger LOG = Logger.getLogger(SimpleAxisClient.class.
            getName());

    private Call getCall(String endpoint, String operation) throws
            ServiceException {

        if (LOG.isDebugEnabled()) {

            LOG.debug("Creating call.....");
        }
        Call result = (Call) (new Service()).createCall();
        try {
            result.setTargetEndpointAddress(new URL(endpoint));

        } catch (MalformedURLException ex) {

            LOG.error(ex);
        }

        result.setOperation(new QName(endpoint, operation), operation);
        if (LOG.isDebugEnabled()) {

            LOG.debug("Done!!");
        }
        return result;
    }
    public Document getDocument(Document doc, String endpoint,
                                String operation) throws Exception {
        Call call = getCall(endpoint, operation);
        Vector result = (Vector) call.invoke(new Object[] {doc});
        //Vector result = (Vector) call.invoke(new SOAPBodyElement[] { new SOAPBodyElement( doc.getDocumentElement() )});
        SOAPBodyElement sbe = (SOAPBodyElement) result.get(0);

        if (LOG.isDebugEnabled()) {

            LOG.debug("Body ricevuto: " +
                      XMLUtils.DocumentToString(sbe.getAsDocument()));
        }
        return sbe.getAsDocument();
    }

    public static void main(String args[]) throws Exception {
        SimpleAxisClient client = new SimpleAxisClient();
        Call miaCall = client.getCall(
                "http://localhost:8082/ServicePublisher/services/Searcher",
                "byFiscalCode");

        DocumentBuilderFactory fac = DocumentBuilderFactory.newInstance();
        fac.setValidating(false);
        DocumentBuilder builder = fac.newDocumentBuilder(); 
        Document doc = builder.parse(new java.io.ByteArrayInputStream("<?xml version='1.0' encoding='UTF-8' standalone='yes'?><ricercaIndividuo><codiceFiscale>XXXXXXXXXXXXXXXX</codiceFiscale></ricercaIndividuo>".getBytes()));
        Vector result =(Vector) miaCall.invoke(new SOAPBodyElement[] {new SOAPBodyElement(doc.getDocumentElement())});
        //System.out.println( "Ho preso: "+ miaCall.invoke(new Object[] {doc}) );
        System.out.println(XMLUtils.DocumentToString((Document) result.get(0)));
    }
}


I'm not able to do the call... infact i have an error that says:

java.lang.IllegalArgumentException: localPart cannot be null
	at javax.xml.namespace.QName.<init>(QName.java:106)
	at javax.xml.namespace.QName.<init>(QName.java:81)
	at org.apache.axis.message.PrefixedQName.<init>(PrefixedQName.java:30)
	at org.apache.axis.message.MessageElement.copyNode(MessageElement.java:2045)
	at org.apache.axis.message.MessageElement.copyNode(MessageElement.java:1997)
	at org.apache.axis.message.MessageElement.<init>(MessageElement.java:197)
	at org.apache.axis.message.SOAPBodyElement.<init>(SOAPBodyElement.java:70)
	at it.eng.test.client.util.SimpleAxisClient.main(SimpleAxisClient.java:110)
Exception in thread "main" 

If i use the string:
Vector result =(Vector) miaCall.invoke(new Object[] {doc});
instead of:
Vector result =(Vector) miaCall.invoke(new SOAPBodyElement[] {new SOAPBodyElement(doc.getDocumentElement())});

I can do the call; in the request i have:

            </ricercaIndividuo>
         </arg0>
      </byFiscalCode>
   </soapenv:Body></soapenv:Envelope>

Why have i the arg0 tag?

In the response i have:

HTTP/1.1 200 OK

   </soapenv:Body></soapenv:Envelope>

Well.... in the output i have:

java.lang.NullPointerException
	at it.eng.test.client.util.SimpleAxisClient.main(SimpleAxisClient.java:112)
Exception in thread "main" 


Can anybody explain to me why this behavior? Thanks
