请大家耐心看完

package com.ssh.common.bean;

import java.util.Map;

import com.opensymphony.xwork2.ActionContext;
import com.ssh.entity.user.service.IUserService;

public class ValidateName {
	private IUserService userService;
	public String valid(String username){//用来检查用户名是否存在
		String result=null;
		if("".equals(username)||username==null) {
			result="请填写用户名";	
		}
		else if(!userService.validateName(username)){
			result="恭喜，"+username+" 可以使用";
		}else{

    public String checkValiCode(String vercode){
    	String result = "";
		Map session = ActionContext.getContext().getSession();
		String ver2 = (String) session.get("rand");
		if(!vercode.equals(ver2)){
			result="验证码不正确";
		}else{
			result = "验证码正确";
		}
		return result; 
    }
	public IUserService getUserService() {
		return userService;
	}
	public void setUserService(IUserService userService) {
		this.userService = userService;
	}
	
	
	
}

其中valid方法可以用，但checkValiCode不行，是哪里出问题了？
问题补充：
ValidateName.checkValiCode(valicode,checkCode);
checkCode是回调

ValidateName.checkValiCode(valicode,checkCode);

 public String checkValiCode(String vercode){  
         String result = "";  
         Map session = ActionContext.getContext().getSession();  
         String ver2 = (String) session.get("rand");  
         if(!vercode.equals(ver2)){  
             result="验证码不正确";  
         }else{  
             result = "验证码正确";  
         }  
         return result;   
     }

函数声明只有1个参数,你传入2个参数了.
