jasper reports

[aydsae]

Hola,
Espero que podáis ayudarme.

El problema es que estoy probando un sitio diseñado por un amigo para aprender el uso de los Jasper Reports. Tengo problemas a la hora de mostrar los reportes. Es algo que no he configurado bien en mi PC porque lo he probado en otra y funciona perfectamente.

Agradezco ayuda para saber si me falta algún driver, librería, o qué?

El error que saqué del log:

Si alguien conoce un link con info para aprender a interpretar estos errores también lo agradezco.

Un saludo cordial.
