El filtro es mío, y el código del filtro es el siguiente:

package glucoweb;

import javax.naming.*;

public class LoginFilter implements Filter
{
private ServletContext context = null;
private DataSource dataSource = null;

protected FilterConfig filterConfig;

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException
{
/* org.apache.log4j.BasicConfigurator.configure(); */
String userID = null;

HttpSession session = ((HttpServletRequest)request).getSession();

//check if object userbean is present in session
if (session.getAttribute("user") == null)
{
//if not, get user data and load it as a session bean
userID = ((HttpServletRequest)request).getRemoteUser();

User user = new User();

//CONSULTO LA BASE DE DATOS PARA PONER LOS DATOS QUE ME INTERESAN
//EN EL ONJETO USUARIO EN EL SCOPE SESSION

//Ojo!! no podemos utilizar el método getDatasource(HttpServletRequest)
//porque esto no es un Action, hay que conseguir un DataSource de otra manera.
//Globals.DATA_SOURCE_KEY : The context attribute key under which our default configured data
//source (which must implement javax.sql.DataSource) is stored, if one is configured for this module.
//al poner un datasource en struts_config.xml, el atributo keyes...
//key: Once created, the DataSource will be stored under an attribute on the application servlet context.
//This attribute holds the name to be used for the context's attribute.
//The default attribute name is specified by the Globals.DATA_SOURCE_KEY String.
context = filterConfig.getServletContext();
dataSource = (DataSource) context.getAttribute(Globals.DATA_SOURCE_KEY);

try {
user = GlucoWebData.getUser(userID,dataSource);
System.err.println("LoginFilter: " + user.getUserID());
System.err.println("LoginFilter: " + user.getRole());
} catch( Exception e ) {

System.err.println("LoginFilter - Setting target to error");

}
session.setAttribute("user", user);

//si existe el objeto en la sesion pero sus atributos son nulos...
} else if (((User)session.getAttribute("user")).getUserID() == null)
{
//if not, get user data and load it as a session bean
userID = ((HttpServletRequest)request).getRemoteUser();

User user = new User();

context = filterConfig.getServletContext();
dataSource = (DataSource) context.getAttribute(Globals.DATA_SOURCE_KEY);

try {
user = GlucoWebData.getUser(userID,dataSource);
System.err.println("LoginFilter: " + user.getUserID());
System.err.println("LoginFilter: " + user.getRole());
} catch( Exception e ) {

System.err.println("LoginFilter - Setting target to error");

}
session.setAttribute("user", user);

}

// pass the request on
chain.doFilter(request, response);
}

public void init(FilterConfig config) throws ServletException
{
this.filterConfig = config;
}

public void destroy()
{
}

}

muchas gracias!
