I just love these crystal ball questions!

The prolog is everything that comes before the root element of your XML document. This can include the XML declaration, comments, internal DTD, and maybe other stuff, but not document content.

You might have more than one root element (a no-no) or stray text or Zeus knows what. We're never going to be able to figure it out for you if you don't show us the code.

hi harebrain,
Thanks for your reply.I will be gratefull to you if you will be able to solve my problem.Here is the code:

for client:

// The Axis package is used to generate and handle the SOAP call
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;

// The rpc package is used to create the RPC call
import javax.xml.namespace.QName;
import javax.xml.rpc.NamespaceConstants;

// The java.net package gives us a URL class
import java.net.URL;

public class HelloWorldClient {
/**
* Test main.
*/
public static void main(String args[]) {
System.out.println("HelloWorld.main: Entering..."

try {
String url = "

http://localhost:8080/axis/HelloWorld.jws";

String sender = "Reader";
Service service = new Service();
Call call = (Call) service.createCall();

call.setTargetEndpointAddress(new URL(url));
call.setSOAPActionURI("sayHello"
call.setEncodingStyle(NamespaceConstants.NSURI_SOAP_ENCODING);
call.setOperationName(new QName("urn:helloworld", "sayHello&quot);
//call.setReturnType(XMLType.XSD_STRING);

String hello = (String)call.invoke(new Object[] { sender } );

System.out.println("The Web Service returned: " + hello);
System.out.println ("HelloWorld.main: All done!"

} catch (Exception exception) {
System.err.println("Caught an exception: " + exception);
}
}
}


For web service:

public class HelloWorld {
/**
* Returns &quot;Hello <sender>!&quot;.
*/
public String sayHello(String sender) {
return &quot;Hello &quot; + sender + &quot;!&quot;;
}
}

Me and my big mouth! I'm afraid I can't help you with this code, but now maybe somebody else can.
