Question

You may find this as duplicate but I'm not getting what is wrong with my code, so please help me out

I'm switching from using struts.xml to struts 2 convention-plugin and having problem with mapping action

there is no action mapped for namespace [/] and action name [login] associated with context path [/eCensus]

LoginAction class

import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.Preparable;

public class LoginAction extends ActionSupport implements Preparable {

    private static final long serialVersionUID = 1L;

    @Override
    public void prepare() throws Exception {
        // TODO Auto-generated method stub
        System.out.println("prepare Login Action");
    }

    @Override
    public String execute() throws Exception {
        // TODO Auto-generated method stub
        return super.execute();
    }

}
