Servlet no me redirije

[elpre]

Pero y eso no lo consigo con el ServletBase que tengo??? el ServletLogin extiende de ServletBase que a su vez extiende de HttpServlet. Este es el código de ServletBase:

Código:

package Servlet;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


public abstract class ServletBase extends HttpServlet {
	
	Error[] errors;
	
	abstract void execute(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException;
	//egin behar duena
	abstract Error[] validate(HttpServletRequest req, HttpServletResponse resp);
	//formularioko kontuak ondo idatzita dauden, Error[]-en jartzen ditu validapenen bat gaizki dagon
	abstract void forwardErrors(HttpServletRequest req, HttpServletResponse resp,Error[] errors) throws ServletException, IOException;
	//erroreak detektatzen ditu eta dispatch egiten du error pagina batera 
	//errors arrayan idazten ditu dauden erroreak
	public abstract  boolean securityRedirect(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException;  
	//segurtasun kontuak. bakarrik sartu al dira logeatuta daudenak...
	abstract void forwardSecurity(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException;
	//zer egin segurtasun barrera pasatzen ez badu
	
	
	protected void doGet(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {process(req,resp);}

	protected void doPost(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {process(req,resp);}
	protected void process (HttpServletRequest req, HttpServletResponse resp) 
			throws ServletException, IOException{
		
		if(securityRedirect(req,resp) == true){
			System.out.println("security");
			errors = validate(req,resp);
		/*	for(int i=0;i<errors.length;i++)
			{
				if(errors[i]!=null)System.out.println("name: "+errors[i].name+"  value: "+errors[i].value);
			}*/
			
			if(errors!=null){
				System.out.println("forward errors");
				forwardErrors(req,resp,errors);//setAttribute de mensaje de error y redireccionar
			}else{
				System.out.println("execute");
				execute(req, resp);
			}
		}else{
			forwardSecurity(req,resp);
		}
		
	}
}
