<mvc:annotation-driven />

funciona la jsp pero no me realiza las redirecciones de páginas.
¿A alguien se le ocurre cual puede ser el error?

Answer 1

Parece que se queje de que un paràmetro que espera tiene que ser un numérico y está recibiendo un nulo...

Yo repasaría los paràmetros de entrada a alguna función que llama Spring automàticamente, por eso no da error al quitar las anotaciones (dejan de funcionar esas funciones con lo que no llega nunca a producirse).
