axis2 wsdl2java client can invoke the generated class

axis2 the faithful know , I encountered this problem , hope to solve :
First, I wrote a simple server-side java class , just a plain java class , as follows:

package com.webservice.server;
  
  import java.util.Random;
  
  
  public class WebServiceServer {
  	
  	public String sayHello(String name){
  		return name + "COME ON!!";
  	}
  	
  	public int getAge(){
  		return new Random().nextInt(30);
  	}
  	
  
  }
  

, and then through the eclipse plugin axis2 generated services.wsdl file , and then I want to pass this wsdl file automatically generated stub classes , the generated class or into the current project, the project directory structure is as follows , the yellow part is I most original writing service side java class :

WebServiceServerStub.java class has generated an error , because the beginning of the program code is written like this :

 public class WebServiceServerStub extends org.apache.axis2.client.Stub
          implements WebServiceServer{
  

It put WebServiceServer this class as an interface , but I most primitive defined service -side code is just a regular java class ah ! So I do not understand why this place !
The next problem is that I want to write client code , and want to apply this auto- generated class to write, to see some of the online wording is:

  WebServiceServerStub wsss = new WebServiceServerStub();//----1
  WebServiceServerStub.SayHello sh = WebServiceServerStub.SayHello();//-----2
  sh.setName("小明"); 
  System.out.println(wsss.sayHello().get_return());
  

This should output in the console : Xiao Ming COME ON! !
But the two can not write , WebServiceServerStub. then simply do not find this SayHello class ( the original sayHello method automatically generates a class ) , so please help solve ! Since learning ! Implore help , ()
------ Solution ------------------------------- -------------
LZ, you try to put sayhello that class in your package posted below look okay class class

By the way . LZ try to package with MAVEN AXIS2 look , AAR packages do not generate their own , and direct MVAEN own generated WAR package can be accessed directly , \
