Problemas con bean y tomcat
Hola he hecho un bean y lo he compilado pero a la hora de que se ejecute en las páginas de jsp me da un error de que el tomcat no puede resolverlo.
Yo he colocado el class en la carpeta /mi proyecto/Web-inf/classes/
Tengo que hacer algo más? Sabes porque me da el siguiente error?
