[jboss-user] [JBoss Web Services Users] - Problem of polymorphism of JBoss WebService

[xiangyingbing]

Dear JBoss developers,
      I spent several days to solve the problem of  polymorphism in JBoss WebService, but failed.
      I googled many articles, Only "http://forums.sun.com/thread.jspa?threadID=5225941" is usefull to me. But it just does NOT work!!

      Please help me. Great Thanks to any tips.

My envirionment:
          jboss-5.1.0.GA-jdk6.
          jdk1.6.0_14_Windows
          Eclipse 3.2

My code:
Server:
--------------------------------------------------------------------------------------------------------------------
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;
	}
	
}
