    <body>
    动态结果 一定不要忘了为动态结果的保存值设置set get方法
    <ol>
    	<li><a href="user/user?type=1">返回success</li>
    	<li><a href="user/user?type=2">返回error</li>	
    </ol>
    </body>

    2.struts.xml

    <struts> 
     <constant name="struts.devMode" value="true" /> 
     <package name="user" namespace="/user" extends="struts-default">        
            <action name="user" class="com.wxh.action.UserAction">
                <result >${r}</result>
            </action>    
        </package>
    </struts>

    3.UserAction.java

    package com.wxh.action;
    import com.opensymphony.xwork2.ActionSupport;
    public class UserAction extends ActionSupport{
    	/**
    	 * 
    	 */
    	private static final long serialVersionUID = 1L;
    	private int type;	
    	private String r;
    	public String getR() {
    		return r;
    	}
    	public void setR(String r) {
    		this.r = r;
    	}
    	public int getType() {
    		return type;
    	}
    	public void setType(int type) {
    		this.type = type;
    	}
    	//动态确定r的值
    	public String execute() throws Exception{
    		if(type==1) r="/userSuccess.jsp";
    		else if(type==2) r="/userError.jsp";
    	    return "success";
