Thanks, I'll take a look at this.
But, after giving this problem some thought I have another question:
Does the class that implements the web service have to be a Java Bean or can
in be a POJO?

Subject: Re: Web Service Method Returns null
Hi,
My comment inline

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";
// when you call hwwsPortType.sayHello( ), this method not get invoked.
}
}
There should be a class implements HelloWorldWebServicePortType
interface have sayHello method and return whatever you want to return,
but not the one in HelloWorldWebService.

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( ) );
}
}
