I would create a constructor in the action, and place a
breakpoint/logging statement in there to make sure the correct action is
beng called. In the HTML you have:
<s:form action="Logon" name="login_form" >
So the action should be /Logon.action, but your configuration is:
<action name="Logon_*" method="{1}" class="packagename.Logon">
Which would seen to imply that the action attribute in the form should
be "Logon_login".

======================================================
and my jsp is
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%@ taglib prefix="s" uri="/struts-tags" %>

<s:textfield label="%{getText('username')}" name="username"/>
<s:password label="%{getText('password')}" name="password" />
<s:submit />
</s:form>
</body>
</html>
======================================================
and struts.xml is
<package name="login" extends="struts-default">
<action name="index" class="packagename.IndexAction">
<result name="success">index.jsp</result>
</action>
<action name="Logon_*" method="{1}" class="packagename.Logon">
<result name="success">result.jsp</result>
<result name="input">login.jsp</result>
</action>
</package>
=======================================================
and Logon.java is
public class Logon extends ActionSupport {
private static final long serialVersionUID = -178540847931051617L;
public static final String loggedIn = "You have loggedin successfully ...";
public static final String notLoggedIn = "Login failed ...";
public static final String _userName = "admin";
public static final String _password = "admin";
public String execute() throws Exception {

setMessage(this.login(getUsername(),getPassword()));
return SUCCESS;
}
private boolean isInvalid(String value) {
return (value == null || value.length() == 0);
}
private String login(String _username,String _password){
if(_username.equalsIgnoreCase(Logon._userName) &&
_password.equalsIgnoreCase(Logon._password))
return loggedIn;
else
return notLoggedIn;
}
private String message;
private String username;
private String password;
public void setMessage(String message){
this.message = message;
}
public String getMessage() {
return message;
}
private String getPassword() {
return password;
}
private void setPassword(String password) {
this.password = password;
}
private String getUsername() {
return username;
}
private void setUsername(String username) {
this.username = username;
}
}
=================================================
Is there any problem in jars or any configuration problem? If somebody has developed a sample application using struts2 j4 version ,Can he/she send me source codes
