>From the service WSDL, you should do
call.setTargetObjectURI("http://www.webserviceX.NET/";);
This will lead to another error, however, since the service uses
document/literal encoding. Apache SOAP only supports rpc/encoded directly.
You can write a client to talk to the service with Apache SOAP, but you have
to create the SOAP envelope manually. Microsoft has a HOW TO on this at
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q308466.

Subject: need your help for trying to understand the error while invoking a
webservice method from a client
Hi!
I am writing an Apache SOAP client to acces a webservice.
I was able to execute a sample client provided for a CurrencyExchange
webservice available on www.xmethods.com <http://www.xmethods.com>. But have
some problems coding & executing a client for the CurrencyConvertor
available on the same site.
Below are the lines coded to invoke a method on it:
URL url = new URL("<http://www.webservicex.net/CurrencyConvertor.asmx>");
Call call = new Call ();

SOAPHTTPConnection con = new SOAPHTTPConnection();
con.setProxyHost("10.9.64.9");
con.setProxyPort(8080);
call.setSOAPTransport(con);
call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
call.setTargetObjectURI("urn:webserviceX-CurrencyConvertor");
call.setMethodName("ConversionRate");
Vector params = new Vector ();
params.addElement (new Parameter("fromCurrency", String.class, fromCurrency
, null));
params.addElement (new Parameter("toCurrency", String.class, toCurrency,
null));
call.setParams (params);
SOAPMappingRegistry smr = new SOAPMappingRegistry ();
Deserializer sd1 = new XMLParameterSerializer();
smr.mapTypes (Constants.NS_URI_SOAP_ENC,
new QName ("", "fromCurrency"), String.class, null, sd1);
smr.mapTypes (Constants.NS_URI_SOAP_ENC,
new QName ("", "toCurrency"), String.class, null, sd1);
call.setSOAPMappingRegistry(smr);
System.out.println("invoke the method call");
Response resp =
call.invoke(url,"<http://www.webserviceX.NET/ConversionRate>");
System.out.println("response received");
if (resp.generatedFault()) {
Fault fault=resp.getFault();
System.out.println(" Fault code: " + fault.getFaultCode());
System.out.println(" Fault string: "+fault.getFaultString());
} else {
Parameter result=resp.getReturnValue();
Double value = (Double)result.getValue();
rate = value.doubleValue();
}
Following is the stack trace for the exception thrown when i try to invoke
the method on the webservice:
Fault string: System.Web.Services.Protocols.SoapException: Server was unable
to read request. ---> System.InvalidOperationException: There is an error in
XML document (5, 2). ---> System.Xml.XmlException: Invalid namespace

Can you kindly let me know what is it that I am missing out or doing wrong.
