I am having some issues running a Struts web app since few days. I tried several solutions from StackOverflow relating to my problem but none of them works.
web.xml:
<display-name>Struts2 Application</display-name>
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>Login.jsp</welcome-file>
</welcome-file-list>
struts.xml:
<struts>
<constant name="struts.enable.DynamicMethodInvocation"
value="false" />
<constant name="struts.devMode" value="false" />
<constant name="struts.custom.i18n.resources"
value="ApplicationResources" />
<package name="default" extends="struts-default" namespace="/">
<action name="login"
class="net.viralpatel.struts2.LoginAction">
<result name="success">Welcome.jsp</result>
<result name="error">Login.jsp</result>
</action>
</package>
</struts>
Login.jsp:
<%@ page contentType="text/html; charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<html>
<head>
<title>Struts 2 - Login Application | ViralPatel.net</title>
</head>
<body>
<h2>Struts 2 - Login Application</h2>
<s:actionerror />
<s:form action="login.action" method="post">
<s:textfield name="username" key="label.username" size="20" />
<s:password name="password" key="label.password" size="20" />
<s:submit method="execute" key="label.login" align="center" />
</s:form>
</body>
</html>
LoginAction.java:
package net.viralpatel.struts2;
public class LoginAction {
private String username;
private String password;
public String execute() {
if (this.username.equals("admin")
&& this.password.equals("admin123")) {
return "success";
} else {
return "error";
}
}
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;
}
}
Libs I have added:
- commons-logging-1.1.3.jar
- freemarker-2.3.19.jar
- ognl-3.0.6.jar
- struts2-core-2.3.15.1.jar
- xwork-core-2.3.15.1.jar
Error accessing URL:

HTTP Status 404 - /StrutsHelloWorld/
type Status report

I tried this tutorial.
There are no errors on my console, problem view.
The error 404 means that resource you have requested is not available, the same referred to the action that is didn't map to the request URL.
FilterDispatcheris deprecated and may not work with the current Struts version, useStrutsPrepareAndExcecuteFilterinstead.in the
struts.xmladd the followingthis will forward you to the login page. Also consider to use absolute paths to the JSP resources.
In the JSP use the form that needs to rewrite to
In the
actionattribute use the action name and providenamespaceas you did in the package configuration.Using
method="execute"is useless in thes:submittag, the methodexecuteused by default, and it will not work because you have turned off DMI in the Struts configuration.Adding libraries over the old libraries in the
WEB-INF/libdoesn't help so much and your application probably would not work, until you remove and replace all lower version libraries with higher version and add new libraries needed by the current version of Struts framework.
