Parsing error when running a SOAP client

Question

New to SOAP. Tring to get get it up an running using some of the Oreilly examples from Java and XML. Anyone with any suggestions to fix the error I am getting. Thanx in advance.
1>This is my simple SAX client:
package xml;
import java.net.URL;
import java.util.Vector;
import org.apache.soap.Constants;
import org.apache.soap.Fault;
import org.apache.soap.rpc.Call;
import org.apache.soap.SOAPException;
import org.apache.soap.rpc.Parameter;
import org.apache.soap.rpc.Response;
public class CDAdder {
public void add(URL url, String title, String artist) throws SOAPException {
System.out.println("Adding CD titled '" + title + "' by '" + artist + "'");
//Build the call object
Call call = new Call();
call.setEncodingStyleURI("urn:cd-catalog");
call.setMethodName("addCD");
call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
//Setup the parameters
Vector params = new Vector();
params.addElement(new Parameter("title",String.class,title,null));
params.addElement(new Parameter("artist",String.class,artist,null));
call.setParams(params);
//Invoke the call
Response response;
response = call.invoke(url,"");
if(!response.generatedFault()) {
System.out.println("Successful CD Addition");
} else {
Fault fault = response.getFault();
System.out.println("Error encountered: " + fault.getFaultString());
public static void main(String[] args) {
try {
URL url = new URL("http://localhost:8081/soap/servlet/rpcrouter");
String title = "Riding the Midnight Train";
String artist = "Doc Watson";
CDAdder adder = new CDAdder();
adder.add(url, title, artist);
} catch(Exception e) {
e.printStackTrace();
2>My service:
package javaxml2;
import java.util.Hashtable;
public class CDCatalog {
private Hashtable catalog;
public CDCatalog() {
catalog = new Hashtable();
catalog.put("Nickel Creek", "Nickel Creek");
catalog.put("Let it Fall", "Sean Watkins");
catalog.put("Aerial Boundaries", "Michael Hedges");
catalog.put("Taproot", "Michael Hedges");
public void addCD(String title, String artist) {
if ((title == null) || (artist==null)) {
throw new IllegalArgumentException("Title or Artist cannot be null.");
catalog.put(title, artist);
public String getArtist(String title) {
if (title == null) {
throw new IllegalArgumentException("Title cannot be null.");
return (String)catalog.get(title);
public Hashtable list() {
return catalog;
3>My deployement descriptor:
<isd:service xmlns:isd="http://xml.apache.org/xml-soap/deployment"
id="urn:cd-catalog"
>
<isd:provider type="java"
scope="Application"
methods="addCD getCD list"
>
<isd:java class="javaxml2.CDCatalog" static="false" />
</isd:provider>
<isd:faultListener>org.apache.soap.server.DOMFaultListener</isd:faultListener>
</isd:service>
4>I have deployed the SOAP Service:
D:\XML-RPC\javaxml2>java org.apache.soap.server.ServiceManagerClient http://loca
lhost:8081/soap/servlet/rpcrouter deploy xml/CDCatalogDD.xml
D:\XML-RPC\javaxml2>java org.apache.soap.server.ServiceManagerClient http://loca
lhost:8081/soap/servlet/rpcrouter list
Deployed Services:
urn:cd-catalog
D:\XML-RPC\javaxml2>
Error when I try using the service:FYI: I am running the client with JBuilder 2005
Adding CD titled 'Riding the Midnight Train' by 'Doc Watson'
Error encountered: parsing error: org.xml.sax.SAXParseException: The value of the attribute "prefix="xmlns",localpart="ns1",rawname="xmlns:ns1"" is invalid. Prefixed namespace bindings may not be empty.

Answer 1

call.setEncodingStyleURI("urn:cd-catalog");
in the SOAP client has to be
call.setTargetObjectURI("urn:cd-catalog");
