ayuda: SecurityFilter.doFilter(SecurityFilter.java:120)

[jaime_zgz]

Tenías razón GreenEyed estaba juntando 2 problemas... el del login y el del filter...

Ya he resuelto lo de JDBC Realm era un problema en la base de datos, ahora hace el login sin problemas, pero falla el LoginFilter al cargar el datasource.

Lanza la siguiente excepción:

El problema está en la línea 99 del filtro:


chain.doFilter(request, response);


el código del filtro es el siguiente:


package glucoweb;

public class LoginFilter implements Filter

private ServletContext context = null;
private DataSource dataSource = null;

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException
{

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

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

User user = new User();

//CONSULTO LA BASE DE DATOS PARA PONER LOS DATOS QUE ME INTERESAN
//EN EL OBJETO 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

//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 {

} catch( Exception e ) {

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

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

System.err.println("LoginFilter: " + user.getRole());
} catch( Exception e ) {

}

}

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