[jboss-user] [EJB 3.0 Users] - Problem of polymorphism Web Service in EJB

[xiangyingbing]

Dear friends,
    I can use pure polymorphism Web Service in Glassfish and JBoss correctly.
    But, after annotated with @Stateless, my codes does NOT work.
    Namely, i can not make my code work in EJB3 environment.

My environment:
    JDK, lates.
    jboss-5.1.0.GA-jdk6
    Windows XP.

My java files:
    
package com.ybxiang.ejbws;
  | 
  | import javax.xml.bind.annotation.XmlSeeAlso;
  | 
  | @XmlSeeAlso({Human.class})
  | public class Animal implements java.io.Serializable{
  | 	private String name;
  | 	private Long age;
  | 	public String getName() {
  | 		return name;
  | 	}
  | 	public void setName(String name) {
  | 		this.name = name;
  | 	}
  | 
  | 	public Long getAge() {
  | 		return age;
  | 	}
  | 	public void setAge(Long age) {
  | 		this.age = age;
  | 	}	
  | 
  | 	public String toString(){
  | 		return "Animal-->name:"+this.getName()+",age:"+this.getAge();
  | 	}
  | }
  | 
  | 
  | 
  | 
  | 
  | 
  | package com.ybxiang.ejbws;
  | 
  | public class Human extends Animal implements java.io.Serializable{
  | 	private String email;
  | 
  | 	public void setEmail(String email) {
  | 		this.email = email;
  | 	}
  | 
  | 	public String getEmail() {
  | 		return email;
  | 	}
  | 	
  | 	public String toString(){
  | 		return "Human-->name:"+this.getName()+",age:"+this.getAge()+","+"email:"+email;
  | 	}
  | 	
  | }
  | 
  | 
  | 
  | 
  | 
  | 
  | 
  | package com.ybxiang.ejbws;

  | public class EJBWebServiceBean implements EJBWebServiceInterface{
  | 	 @WebMethod
  | 	 public void passParameter1(String s){
  | 		 System.out.println("------------String is got:"+s);
  | 	 }
  | 	 @WebMethod
  | 	 public void passParameter2(Animal a){

  | 		 }else{
  | 			 System.out.println("------------List is null.");
