*/
public class LiziForm extends ActionForm{
private String userName=null;
private String passWord=null;
public String getUserName(){
return userName;
}
public void setUserName(String userName){
this.userName=userName;
}
public String getPassWord(){
return passWord;
}
public void setPassWord(String passWord){
this.passWord=passWord;
}
public void reset(ActionMapping mapping,HttpServletRequest request){
this.userName=null;
this.passWord=null;
}
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request){
ActionErrors errors=new ActionErrors();
