Hi all.I'm newbie to web service and Axis; i have a problem.... i have written
a very simple Web Service; it's code is:
import java.io.Serializable;
import org.w3c.dom.Document;
public class PersonHandler implements Serializable {
/**
* Web service esposto. Invocato esso accetta un document e lo restituisce
in uscita.
* @param doc Document -il document .
* @return Document -il document.
*/
public Document getUserProfile(Document doc) {
return doc;
}
}
Well, i use Axis1.2RC2, JBuilder 2005, Windows XP Home Ed SP2, JBoss 3.2.6; i
want ot create a web service not style RPC but Message.... JBuilder creates
this files:

I have written a simple class that creates the document; its code is:
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.FactoryConfigurationError;
import javax.xml.parsers.ParserConfigurationException;
public class Parser {
/**
* Mi genero il document da passare al web service.
* @param queryString String -come deve essere il documento
* @return Document -il documento creato
* @exception FactoryConfigurationError -se ci sono problemi nella
creazione della Factory
* @exception ParserConfigurationException -se ci sono problemi nel
parserizzare il documento
*/
public Document generateDocument(String queryString) throws
FactoryConfigurationError, ParserConfigurationException {
DocumentBuilder builder =
DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = builder.newDocument();
Element root = doc.createElement("queries");
root.setAttribute("tipoServizio", "testPMM");
doc.appendChild( root );
Element tag = doc.createElement( "query" );
root.appendChild( tag );
tag.appendChild( doc.createTextNode( queryString ) );
return doc;
}
}
Then i have created a simple client:
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.message.SOAPBodyElement;
import org.apache.axis.utils.XMLUtils;
import org.apache.axis.MessageContext;
import org.apache.axis.Message;
import javax.xml.rpc.ServiceException;
import java.util.Vector;

import java.io.Reader;
import java.io.StringReader;
import javax.xml.namespace.QName;
import org.apache.log4j.Logger;
import java.net.URL;
import java.net.MalformedURLException;
public class SimpleAxisClient {
/**
* Il logger
*/
private static final Logger LOG = Logger.getLogger(SimpleAxisClient.class.
getName());
/**
* Preparo il l'oggetto Call da utilizzare
* @param endpoint String -l'endpoint da utilizzare
* @param operation String -l'operazione da invocare
* @return Call -il Call generato.
* @throws ServiceException -Se ci sono problemi col servizio
*/
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;
}
/**
* Invoco il web service passandogli il Document generato
* @param doc Document -il Document generato.
* @param endpoint String -l'endpoint del servizio.
* @param operation String -l'operazione da invocare.
* @return Document -il document in uscita al webService
* @throws Exception
*/
public Document passDocument(Document doc, String endpoint,
String operation) throws Exception {
Call call = getCall(endpoint, operation);
Vector result = (Vector) call.invoke
(new SOAPBodyElement[] {new SOAPBodyElement(doc.
getDocumentElement())});
SOAPBodyElement sbe = (SOAPBodyElement) result.get(0);
MessageContext mc = call.getMessageContext();
Message m = mc.getRequestMessage();
Document docreq = m.getSOAPEnvelope().getAsDocument();
if( LOG.isDebugEnabled() ){
LOG.debug("Body trasmesso: " +
XMLUtils.DocumentToString(docreq));
}
return docreq;
}
}
Well when i try this client (i have created 2 web app one that contains the web
service and one that contains the client), i have this error(i have printed the
full stacktrace):
