Accessing web service from standalone Java client

[guptah]

Hi,

I am trying to access a web service using standalone Java client and I get below mentioned exception. The same service works from a JSP page.

AxisFault

Any help is appreciated.

Here is the client class code.

package client;

import javax.xml.rpc.Service;
import javax.xml.rpc.JAXRPCException;
import javax.xml.namespace.QName;
import javax.xml.rpc.Call;
import javax.xml.rpc.ServiceFactory;
import javax.xml.rpc.ParameterMode;

public class CPRWebServiceClient {


private static String qnameService = "CPRWebServices";
private static String qnamePort = "CPRWSIF";

private static String BODY_NAMESPACE_VALUE =
"urn:foo";
private static String ENCODING_STYLE_PROPERTY =
"javax.xml.rpc.encodingstyle.namespace.uri";
private static String NS_XSD =
"http://www.w3.org/2001/XMLSchema";
private static String URI_ENCODING =
"http://schemas.xmlsoap.org/soap/encoding/";

public static void main(String[] args) {

String endpointAddress = "http://gupta:8080/cprwebservices/cprws";

try {
ServiceFactory factory = ServiceFactory.newInstance();
Service service = factory.createService(new QName(qnameService));

QName port = new QName(qnamePort);

Call call = service.createCall(port);
call.setTargetEndpointAddress(endpointAddress);

call.setProperty(Call.SOAPACTION_USE_PROPERTY,
new Boolean(true));
call.setProperty(Call.SOAPACTION_URI_PROPERTY,
"");
call.setProperty(ENCODING_STYLE_PROPERTY,
URI_ENCODING);
QName QNAME_TYPE_STRING =
new QName(NS_XSD, "string");
call.setReturnType(QNAME_TYPE_STRING);

call.setOperationName(
new QName(BODY_NAMESPACE_VALUE,"sayHello"));
call.addParameter("String_1", QNAME_TYPE_STRING,
ParameterMode.IN);
String[] params = { "Himanshu!" };

String result = (String)call.invoke(params);
System.out.println(result);

} catch (Exception ex) {
ex.printStackTrace();
}
}

Again, you need to provide a sample deployment in JIRA that allows me to reproduce what you are seeing? Ideally the client would be a Servlet, so that I only have to click on a link.
