关于struts的验证问题！！

我i点提交后，。，会进入一个action执行查询。。同时还要服务器去验证。。文本框为不为空
。。
这种情况。。该怎么办呢。？不用js验证、。。
我写了个，但是点提交后。
它直接没有验证就只想了action中的方法执行查询了。没有经过服务器验证。。有什么方法让它先经过服务器验证，在执行方法呢？|

你写的验证方法是validate吗？那是不是你的action没有继承ActionSupport
用validate
action继承ActionSupport
不是得··我用的struts1.2在action中写的是自己定义的方法、package com.foods.web.action;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.DynaActionForm;
import org.apache.struts.actions.DispatchAction;import com.foods.bizI.UsersBizI;
import com.foods.bizImpl.UsersBizImpl;
import com.foods.entity.Users;public class LoginAction extends DispatchAction{ public ActionForward loginUser(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
DynaActionForm loginForm = (DynaActionForm)form;
Users us = new Users();
us.setUserName(loginForm.getString("username"));
us.setUserPass(loginForm.getString("userpass"));
UsersBizI ub = new UsersBizImpl();
Users u = (Users)ub.selUser(us);
if(u!=null){

return mapping.findForward("loginSuccess");
}else{

return mapping.findForward("loginError");
}

}
