A question encountered in struts !! Please take a look and help me solve it!

What I did was the login interface of the test system, and the following problems occurred:
Please take a look at some of my interception code first:
1. Login interface (main.jsp)
...............
<html: form action = "/ login1.do" focus = "username">
<html: hidden property = "usertype" value = "1" />
<table width = "100%" height = "1002%" border = "0" bgcolor = "# FFFFFF" class = "Xsmall">
<tr>
<td height = "60">
<div align = "center">
<strong> Examination system data management login window </ strong>
</ div>
<div align = "center">
<strong> <html: errors property = "error" /> </ strong>
</ div>
</ td>

</ tr>
<tr>
<td height = "26">
<div align = "center">
<img src = "/ exam / img / stu_1.gif" width = "16" height = "16" align = "absmiddle">
Manage account:
<html: text property = "username" styleClass = "Sborder" styleId = "saname" size = "12" maxlength = "20" /> <strong> <html: errors property = "username" /> </ strong>
</ div>
</ td>
</ tr>
<tr>
<td height = "26">
<div align = "center">
<img src = "/ exam / img / useronline.gif" width = "16" height = "16" align = "absmiddle">
Management password:
<html: password property = "password" styleClass = "Sborder" styleId = "saps" size = "12" maxlength = "20" redisplay = "false" /> <strong> <html: errors property = "password" /> </ strong>
</ div>
</ td>
</ tr>
<tr>
<td height = "26">
<div align = "center">
<html: submit property = "submit" value = "OK" styleClass = "Sborder"> </ html: submit>
<html: reset property = "reset" styleClass = "Sborder" value = "rewrite"> </ html: reset>
</ div>
</ td>
</ tr>
</ table>
</ html: form>
..............................
2. Specific verification action (loginaction):
..............................
public ActionForward execute (ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
Login1Form login1Form = (Login1Form) form; // TODO Auto-generated
// method stub\
String username = login1Form.getUsername ();
String password = login1Form.getPassword ();
String usertype = login1Form.getUsertype ();

// call the method of the model
LoginDAO dao = new LoginDAO ();
Bean_admin admin = dao.getAdmin (username);
ActionErrors errors = new ActionErrors ();
// get a reference to the session object
HttpSession session = request.getSession ();

if (admin == null) {
ActionError error = new ActionError ("login.error");
errors.add ("error", error);
this.saveErrors (request, errors);
return mapping.findForward (mapping.getInput ());
} else {
if (admin.getPassword (). equals (password)) {
session.setAttribute ("user", username);
return mapping.findForward ("suc");
} else {
ActionError error = new ActionError ("login.password.error");
errors.add ("password", error);
this.saveErrors (request, errors);
return new ActionForward (mapping.getInput ());
}

}
3.property file
# Resources for parameter 'com.neusoft.struts.ApplicationResources'
# Project P / exam


# Login1Form
username.null = <li> username is null </ li>
password.null = <li> password is null </ li>
#LoginAction
login.username.error = <li> username is error </ li>
login.password.error = <li> password is error </ li>

## struts-config.xml
#LoginAction ------ ExamException
login.error = <li> login is error! please try again </ li>
#Exception error
error.key = <li> error try again </ li>
#QuestionAction ------ ExamException
questionlist.query.error = <li> query is error </ li>
#QuestionDelAction ------ ExamException
questionlist.delete.error = <li> delete is error </ li>



#ExamRequestProcessor ------- processPreprocess
no.login = <li> please login now </ li>
The problem now is that when the user name and password are both wrong, there is no error message, but a blank interface is transferred ...
What do you think is wrong with me ???????????

Do your web.xml and struts-config.xml indicate the location of this resource file? Or do you declare that you want to use this resource file?

Can you be more specific? upstairs

return new ActionForward (mapping.getInput ());
Did you set up the input page
