各位大哥哥麻烦你们进来一下!关于struts的问题

Question

这是我的一个struts的longin界面!
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<html:form action="register.do">
 your name:<html:text property="username"/><br >
 passowrd: <html:password property="password1"/><br >
  reenter password:<html:password property="password2"/><br >
  <html:submit value="Regist"/>
</html:form>
这是我的struts-config.xml的文件<?xml version="1.0" encoding="ISO-8859-1" ?> 
<!DOCTYPE struts-config PUBLIC

public void setpassword1(String password1)
{
this.password1=password1;
}public void setpassword2(String password2)
{

}
}
RestistAction .java
package tes;
import org.apache.struts.action.*;

import java.io.*;public class RestistAction extends Action
{
public ActionForward perform (ActionMapping mapping,ActionForm form,HttpServletRequest req,HttpServletResponse res) { 
//  ①Cast the form to the RegisterForm 
TestActionFrom rf = (TestActionFrom) form; 
//String username = rf.getname() ;
String password1 = rf.getpassword1() ;
String password2 = rf.getpassword2(); 
//  ②Apply business logic 
if (password1.equals(password2)) 
{ 
return mapping.findForward("sucess.jsp"); 
} 
else{

//  ④Return ActionForward for failure 
return mapping.findForward("failed.jsp"); 

} 
}
}
为什么运行register.jsp老出错啊!为什么啊?

Answer 1

找不到类org.apache.struts.taglib.html.MessagesTei,是不是包没倒进来啊.

Answer 2

把Action中负责转向的代码改成这样if (password1.equals(password2)) 
{ 
  return mapping.findForward("sucess"); 
} 
else
{
  return mapping.findForward("failed"); 
}

Answer 3

没有用啊! 我试过了啊!是不是不要配置web.xml啊?晕了!

供参考:

注: 在Struts.config.xml中
<forward name="failed" path="/index.jsp" />
<forward name="success" path="/ShowPage.jsp" />
path后面的转向页面要改成你项目中有的页面
