     }

 }

package com.awp.test.form;

import org.apache.struts.action.ActionForm;

public class FirstForm extends ActionForm {

	private String	name;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

}

 

 package  com.awp.test.form;

 import  org.apache.struts.action.ActionForm;

 public   class  SecondForm  extends  ActionForm {

     private  String  name;

     public  String getName() {
         return  name;
     }

     public   void  setName(String name) {

Action必须继承DispatchAction，感觉其实一个action还是只能对应一个form

这里的方法其实是利用action的path 多个path可以指向同一个action。
