Buenas, tengo un Servlet que crea un Thread para que se ejecute diariamente. Esto sólo quiero que lo cree cuando arranco el servidor. El tema es que al arrancar el servidor, entra 2 veces por el servlet y programa el Thread 2 veces.. No tengo ni idea de porqué entra 2 veces, os pongo el codigo del Servlet y del web.xml a ver si me podeis echar una mano.
Muchas gracias!
