Hola amigos, primero que todo Feliz Año 2008 para todos, los mejores deseo

Bueno recurro a Ud por un pequeño problemita que se me esta presentando a la
hora de llamar a una funcion desde java, estoy revisando la funcion varias
veces para dar con el problema pero la verdad no puedo dar con el error
quizas algunos de Uds que me pueda apoyar.
Esta es mi funcion:

a la hora de llamarlo desde mi codigo en java, enviando los parametros me
arroja el siguiente error:

select * from
sp_insert_cabezera_sbs(?,,0045275213,2007-11-30,,,1,07087112,1,002,0.0,0.0,

segun lo que entiendo quizas algun parametro este mal tipado o no esten
correctos el numero de parametros pero como les dije ya revise varias veces
y aparentemente tego los parametro correctos.

Quizas alguno de Uds me pudiera ayudar. De antemano les agradezco la ayuda
prestada.

Saludos.
