I've created my projects since my first post so come class and

To respond to your comment, my client side code does have an
implementation
of the "port type" interface. See the code below (remember the name
changes):
The impl class should be used on server side, which is deployed into
tomcat server in your case
I'm sure that the problem is on the client side since the Tomcat
console shows the
SOAP messages for the call to the server; the sayHello( ) called
message is mine. See
the console message text below the source code.
I'm a little bit confused here, in the impl class you appended here,
the log is
Executing operation sayHello
but the printed log is
SayHello( ) in the HelloWorld Web Service was called!
Is there another impl class in tomcat printed out this log?
You should have only one impl class.
I also just noticed a comment in the HelloWorldPortTypeImpl class.
It says the
class is not complete. Can you provide some info on what I need to
complete it?
Thanks

I believe the impl class is auto-generated using wsdl2java tool, it's
just a skeleton, so you should put your business logic in the
method(sayHello) to complete it.
But seeems this impl class isn't the one get invoked from tomcat.

Subject: Re: Web Service Method Returns null
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?

Hi,

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.
