Hi ,
I am getting following exception while processing my login application.

HTTP Status 404 - No result defined for action fms.ngo.action.LoginAction and result success

login.jsp:

LoginAction.java:

package fms.ngo.action;

import com.opensymphony.xwork2.ActionSupport;
import fms.ngo.dao.LoginDao;
import java.sql.SQLException;
import java.util.Map;

import org.apache.struts2.dispatcher.SessionMap;
import org.apache.struts2.interceptor.SessionAware;

public class LoginAction  extends ActionSupport implements SessionAware{
    
    private String username;
    private String password;
    SessionMap<String,String> smap;
    
    public void setUsername(String username){
        this.username=username;
    }
    public String getUsername(){
        return username;
    }
    
    public void setPassword(String password){
        this.password=password;
    }
    public String getPassword(){
        return password;
    }
    public LoginAction() {
    }
    
    public String execute() throws SQLException{
        
       
        if(LoginDao.validate(username, password)){
              return "success";
         }else{
              return "error";
        }
    }

@Override
    public void setSession(Map map) {
       smap = (SessionMap)map;
       smap.put("login", "true");
    }
    
    public String logout(){
        smap.invalidate();
        return "success";
    }
}

I added Code Tags to your post. They preserver your formatting and make your code easier to read.
I don't see anything obviously wrong with your code. Are you certain the version you posted is the version that is running on your server?
By the way, don' t do this:

It breaks the MVC model of the application and will not work if you use Struts tags in your page. All URL's in a Struts application should go to an action. Struts can send a request directly to a JSP if you don't want to use an action class.

How are you building and deploying the application?
What tutorial are you following?

I don't see any code in that tutorial that resembles the code above. Have you made your own modifications?
Are you rebuilding the application and redeploying the WAR to Eclipse every time you make changes and go to test?
Are there any errors in the Tomcat log?
