[org.apache.struts2.dispatcher.Dispatcher] Could not find action or result Error

Hello to all, i tried to code the following simple struts but encounter this error during run time.

index.jsp

LoginAction.java

/**

package com.peter.action;

//import org.apache.struts2.convention.annotation.Namespace;
import org.apache.struts2.convention.annotation.ResultPath;

import com.opensymphony.xwork2.ActionSupport;

/**

//@Namespace("/") To define URL namespace
@ResultPath("/") // To instruct Struts where to search result page(jsp)
public class LoginAction extends ActionSupport {
	
	private String username, password;
	/**

	 */
	private static final long serialVersionUID = -8992836566328180883L;

/**

	public LoginAction() {
		// TODO Auto-generated constructor stub
	}

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;
	}
	
	@Override
	@Action(value = "login", results = 
		{@Result(name="success", location="welcome.jsp")})
	public String execute() {
		return SUCCESS;
	}
}

AFAIK, the scanning methodology of struts will scan the default packages named struts2 for any annotated class but i have instructed struts2 to scan in com.peter.action using init-param but still unable to find the class. It is pretty weird.

Please help.

Hi,I think you should add a file named "struts.xml" in the path of "WEB-INF/classes"

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <constant name="struts.enable.DynamicMethodInvocation" value="false" /> <constant name="struts.devMode" value="true" /> <package name="index" extends="struts-default"> <action name="loginpage" class="com.peter.action.LoginAction"> <result>index.jsp</result> </action> </package> </struts>

I using annotation approach rather than xml mapping approach.
