Web Service Method Returns null

[Michael]

Recently I've posted several issues I've been having using Eclipse Helios 
(3.6), CXF runtime (2.3.0), Tomcat (6.0) and Java (1.6.0_22).  As is often the 
case the cause of the problem was user error and quite simple to remedy.

Simply, my WSDL soap:address was pointing to my deployed WSDL location not my 
service location.  The was the cause of the content type error I was getting in 
my client.

I found a good description of the CXF Servlet functionality and the 
cxf-servlet.xml and was able to provide the correct soap:address in my WSDL.

The only problem I have remaining is my web service is returning a null value 
when it should be returning a string saying hello from the web service.  I'm 
posting some code and my WSDL below.

Can someone take a look at this and see if you can tell me what I might be 
doing wrong?  If you need more information just let me know what to post.

package org.self;

import javax.jws.WebService;

@WebService(targetNamespace = "http://self.org/";, 
            portName = "HelloWorldWebServicePort",
            serviceName = "HelloWorldWebServiceService")
public class HelloWorldWebService
{
 public String SayHello( )
 {
  return "Hello World  From HelloWorldWebService On Tomcat";
 }
}

package org.self;

public final class Client
{
    public static void main(String args[])
    {
        HelloWorldWebService hwws = new HelloWorldWebService( );
        HelloWorldWebServicePortType hwwsPortType = 
                                        hwws.getHelloWorldWebServicePort( );
        System.out.println( hwwsPortType.sayHello( ) );
    }
}
