Hola,
Resulta que tengo lo siguiente:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib uri="struts-html" prefix="html" %>
<%@ taglib uri="struts-bean" prefix="bean" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

Utilizo Tomcat 6 con la versión de struts 1.3.9.
Hay algo que no esté bien configurado o hay alguna incompatibilidad la última versión de tomcat con dicha versión de struts?.
Llevo todo el día y soy incapaz de solucionarlo.
Por favor, alguien me puede echar una mano?.
Gracias y saludos!!
